Vote “no” on the proposed constitutional amendment to create a “transportation lockbox”

Updated Oct. 10 with more examples of why this could be a problem. Updated Oct. 13 to include CMAP’s review of the amendment. I also posted an alternative version on my new Medium account

Illinois voters are being asked in the current election – early voting has started – to support or opposed a constitutional amendment that would restrict spending of certain revenue sources.

The amendment to the Illinois constitution says that revenues derived from transportation sources – gas and related taxes, license and registration fees, sales taxes for transit, airport fees – can only be used to fund transportation initiatives. (see full text below).

The problem this amendment intends to solve is that sometimes Illinois legislators spend transportation funds on non-transportation projects, people, and services, depending on their priorities at the time – even when existing laws says they can’t.

Your ballot says: “The proposed amendment adds a new section to the Revenue Article of the Illinois Constitution. The proposed amendment provides that no moneys derived from taxes, fees, excises, or license taxes, relating to registration, titles, operation, or use of vehicles or public highways, roads, streets, bridges, mass transit, intercity passenger rail, ports, or airports, or motor fuels, including bond proceeds, shall be expended for other than costs of administering laws related to vehicles and transportation, costs for construction, reconstruction, maintenance, repair, and betterment of public highways, roads, streets, bridges, mass transit, intercity passenger rail, ports, airports, or other forms of transportation, and other statutory highway purposes, including the State or local share to match federal aid highway funds.”

A “yes” vote means you want the Illinois Constitution to have this amendment.

A ChiHackNight member asked the #transportation channel in our Slack about this amendment.

Just got my copy of Proposed Amendment to the Illinois Constitution and bicycle and pedestrian paths are perhaps intentionally not listed as possible places to spend transportation tax revenue. Thoughts?

Very little (oh, so little) money is spent on bike and pedestrian things. Despite what you’ve read, there’s no way to guarantee that the recovered money – the small portion that’s being diverted – would be used to enlarge the pot spent on bike, pedestrian, or transit projects.

Existing laws dictate how the money is supposed to be spent

Many of the money categories in the amendment are already protected by either state or federal law. For example, the Passenger Facility Charge that each airline traveler pays to each airport on their itinerary can only be used on certain capital improvement and maintenance projects at that airport. The PFC differs by airport.

And just so we’re clear, there is no such thing as a “road tax” or “driving tax” in any part of Illinois. There is no fee for anyone to use the roads. What gas taxes are supposed to be spent on, first, and then allowed to be spent on, second, are defined in 35 ILCS 505/8 (from Ch. 120, par. 424). 

Bike lanes and sidewalks are rarely called out separately because they are part of streets and roads, which are funded, and I don’t think it’s significant that the constitutional amendment doesn’t list “bicycles” and “pedestrians”.

It’s up to IDOT and other agencies that have jurisdiction over a road to choose to include those things as part of larger road changes. This constitutional amendment won’t change any policies, which are already mildly supportive of bike and pedestrian infrastructure.

Priorities and policy makers are the problem

I oppose this on the grounds that it restricts setting state priorities while it doesn’t actually prioritize anything within transportation.

Sometimes there are things that are more important than what the state buys with transportation money.

I have a huge problem with those things it buys, though. The priorities that Illinois legislators have for spending transportation moneys isn’t going to improve.

The state built the MidAmerica-St. Louis airport in Mascoutah for $313 million to serve as a “secondary” airport to the St. Louis airport. It opened in 2000. There are only flights to tourist destinations in Florida; the St. Louis airport never had a capacity problem.

The Illinois Department of Transportation wants to extend the St. Louis light rail through rural areas for 5.3 miles, but is still obtaining funding. However, they are spending about $300,000 annually on something for this project.

Illinois budget line item screenshot

A screenshot of the Illinois FY17 enacted appropriations showing spending $330,010 annually for a project to extend a light rail station to an underused airport that cost the public $313 million.

That is exactly the kind of thing that has to stop and this amendment doesn’t do it. That money can still be spent on bad projects. There’s no shortage of bad projects, but there’s also no shortage of good projects that don’t get funded. States are already spending most of their money on new roads instead of maintaining existing ones.

Since projects are often selected and prioritized to serve political needs, and politicians oversee specific geographies, good projects will still linger in some geographies while bad projects are implemented in others.

In other words, the $300,000 on spending for the light rail extension to the underused airport can’t go to build pedestrian overpasses along well-used multi-purpose trails in DuPage County. It’s going to stay in that downstate legislator’s district because “economic development”.

Staff at the Chicago Metropolitan Agency for Planning, Chicagoland’s designated regional planning organization, issued a memo to the board a few days before I wrote this describing that the amendment is “unclear” on so many topics. They cite their discussions with unnamed amendment proponents who explain how the lack of clarity won’t be a problem because the General Assembly can pass laws clarifying that bike lanes won’t need a dedicated user fee if the amendment passes and that it doesn’t impinge on the rights of home rule cities to use gas taxes as they need to.

Spending is based on politics, not performance or need

With the amendment, the state will have to dream up some other transportation project in that district – I see a highway widening in their future. Without the amendment, the state could use that money for an important project in that area, but even that isn’t supposed to happen because the state already has laws dictating how project-specific bond funds can be spent.

This is also the problem with the Illiana Tollway that Governor Quinn so much wanted to build to gain favor with Southland legislators.

Whatever the case is, adhering more to performance (merit) measures on transportation spending – rather than political and district appeasement – is the most important change we can make.

It makes us inflexible

Finally, I question the amendment text. It’s hardly possible or easy for us non-legislators to know if the text covers everything that transportation funds are currently allowed to be spent on. What if there’s some project that turns out not to be an eligible recipient for these funds? Do we wait for the next election when we can get another constitutional amendment on the ballot, or hope that the Illinois Supreme Court will interpret the amendment to favor that project?

In fact, we already have a lot of laws that say how transportation-derived moneys are to be spent. The amendment, then, is a solution to the problem of trusting our state legislators.

The Civic Federation says that money is transferred from the various transportation funds to close budget gaps. “Limiting access to transportation-related revenues such as motor fuel taxes and motorist user fees could put additional strain on the State’s general operating resources” and “similarly affect local governments”. They also said that year-to-year figures of transfers and diversions have been calculated differently.

Additionally, DOT workers’ pensions may be paid for by transportation funds. Does this amendment cover that provision? If not, where else in the state’s budget would their pensions be funded?

Some of the work done by staff at other state departments is funded by some transportation user fees. Would the lockbox cut off their funding supply? A little of the work each department can be considered transportation related, but will the road lobby proponents of this amendment see it that way?

I dislike the inflexibility the amendment creates. Constitutions are meant to protect our rights. I don’t think that there’s a right that gas taxes must be used to pay for roads, while a sliver goes to build new CTA stations.

My writing partner at Streetsblog Chicago, John Greenfield, wrote an article that interviewed leaders at three transportation advocacy groups who were all in favor of the proposed amendment. The Tribune editorial he responded to is against it because it seems like a scam that the road lobby is promoting.

I am not in favor of the amendment.

Playing around with Chicago data: who’s running red lights?

Range Rover with Illinois license plate "0"

A Range Rover with Illinois license plate “0” is seen moving 40 MPH in a 30 MPH zone through a red light at Ashland and Cortland.

I’m just seeing who’s driving around Chicago one night, using the Tribune-published dataset of over 4.1 million tickets issued from red light cameras.

The City of Chicago has installed at least 340 red light cameras since the mid-2000s to reduce the number of people running red lights and crashing. They’re supposed to be installed at intersections where there’s a higher-than-average rate of right angle (“T-bone”) crashes, which are more injurious than other typical intersection crash types.

Assessing safety wasn’t the Tribune’s story angle, though. It was about showing spikes in the number of tickets issued, which I verified to some extent. The article called the tickets issued during these spikes “undeserved” and “unfair”. The data doesn’t have enough information to say whether or not that is the case; a video or extensive photo review is necessary to rule out rolling right turns while the light was red (a much less dangerous maneuver unless people are trying to cross the street).

The first query I ran assessed the number of people who get more than one ticket from a red light camera. Since I was tired my query was a little sloppy and it missed a lot of more useful order choices and didn’t select the right fields. I fell asleep and started again in the morning. This time, I got it right in just two tries – I needed to try again because I mistakenly put HAVING before the GROUP BY clause.

Here’s the first query, in its final form, to retrieve the number of tickets for each license plate in each state (I assumed there may be identical license plates among states).

select max(ticket_number), max(timestamp), license_plate, state, count(*) AS count FROM rlc_tickets group by license_plate, state HAVING count(*) > 1 order by count DESC NULLS LAST

It resulted in 851,538 rows, with each row representing a unique license plate-state combination and the number of red light violations that combination received. You can reasonably assert that cars don’t change license plates more than a couple times in a single person’s ownership, meaning you can also assert that each row represents one automobile.

851,538 vehicles, which make up 35.1% of all violators, have received 2,601,608, or 62.3%, of the 4,174,770 tickets. (There are 2,424,700 license plate-state combinations, using the query below.)

select count(ticket_number) from rlc_tickets group by license_plate, state

Here’re the top 10 vehicles that have received the most violations:

  1. SCHLARS, IL, 78
  2. 9720428, IL, 59
  3. 8919589, IL, 57
  4. A633520, IL, 52
  5. 3252TX, IL, 45
  6. A209445, IL, 44
  7. N339079, IL, 44
  8. X870991, IL, 41
  9. 239099, IL, 41
  10. 4552985, IL, 40

The next step would be to design a chart to show these vehicles’ activity over the months – did the vehicles’ drivers’ behavior change, decreasing the number of red light violations they received? Did the vehicle owner, perhaps a parent, tell their child to stop running red lights? Or has the vehicle owner appealed erroneously-issued tickets?

When I ran one of the first, mistaken, queries, I got results that put license plate “0” at the top of the list, with only nine tickets (license plates with two or more zeros were listed next).

I googled “license plate 0” and found a 2009 Tribune article which interviewed the Range Rover-driving owner of license plate “0” and the problems he encountered because of it. The City of Chicago parking meter enforcement staff were testing new equipment and used “0” as a test license plate not knowing such that license plate exists. Tom Feddor received real tickets, though.

I then looked up on PhotoNotice the license plate and ticket violation number to find, indeed, the license plate belonged to someone driving a Range Rover at Ashland Avenue and Cortland Street on July 17, 2008. An added bonus was Feddor’s speed in that Range Rover: the camera recorded the car going 40 MPH in a 30 MPH zone.

I was done browsing around for the biggest offenders so next I wondered how many tickets were issued to vehicles licensed in Arizona, where U-Haul registers all of its nationwide vehicles. Arizona plates came in 29th place for the greatest number of tickets.

select count(*) AS count, state from rlc_tickets group by state order by count DESC NULLS LAST

As you may have expected, four surrounding Midwest states, and Ohio, rounded up the top five states after Illinois – but this isn’t notable because most visitors come from there and they each only comprise less than 1.3% of the total tickets. The next state was Florida.

  • 3,986,739, IL
  • 51,104, WI
  • 40,737, MI
  • 27,539, IN
  • 8,550, OH
  • 7,684, MN
  • 7,139, FL

What’s next: I’m working on finding a correlation between the number of reported crashes, and type, at intersections with red light cameras and the number of tickets they issued. I started doing that before running the numbers behind this blog post but it got complicated and it takes a long time to geospatially compare over 500,000 crash reports with over 4.1 million red light tickets.

What else do you want to know?

I will delete all comments that don’t discuss the content of this post, including comments that call red light cameras, or this program, a “money grab”.

Compiling and mapping Chicago-area campgrounds

I’m adding Chicago-area campgrounds to the Chicago Bike Guide to entice new users and to espouse the enjoyment of medium-distance bike camping (which I’ve now done officially once, earlier this year).

<The Chicago Bike Guide is available for Android and iOS.>

I’m taking a systematic approach to finding all the publicly-owned campgrounds in the area by looking at primary sources.

First, though, I’ve used Overpass Turbo to create a list of all existing campgrounds in OpenStreetMap. You can see a gist of these places.

Camp sites at Greene Valley forest preserve I mapped.

Camp sites at Greene Valley forest preserve I mapped.

The next method is to find out which campgrounds are operated by the county forest preserves, which are usually well-documented on their respective websites. Then I will look at state parks in Illinois, Indiana, and Wisconsin, operated by states’ respective Departments of Natural Resources (DNR). Next I will look at national parks and finally commercial campgrounds.

The app will display campground information such as alcohol rules, if cabins or lodging is available, and how you can get there (which trails or train lines).

I’ve so far mapped the campgrounds in two ways, as nodes and as areas. At the Greene Valley forest preserve in DuPage County, for example, I’ve mapped the 11 individual camp sites (see map), but at Blackwell forest preserve in the same county, I’ve mapped the area as the camp site (see map).

Blackwell has over 50 sites in a discrete area and it’s more efficient to map them as a single node, while Greene Valley had far fewer sites but scattered over a couple areas.

A new freeway depreciates itself and the city as fast as your new car

A Metra train bypasses congested automobile traffic on the free-to-use Kennedy Expressway. 

Elly Blue wrote about automobile depreciation last week. Depreciation is the value of the automobile that disappears because it’s not as valuable anymore, for reasons of mechanical decay and the “used” factor.

Depreciation is, for many individual consumers a hidden cost. But any responsible accounting of the costs of driving includes it as one of the largest associated with car ownership. The fact that such a large and unprofitable investment is necessary to living and working in most areas of this country is a major source of poverty and failure to get ahead for people and families, and is a hidden source of poverty on a national scale.

The same exact principle is at work in our road system.

It’s depreciation at the societal level. It’s irresponsible not to plan for it, but we do not. A freeway, once built, immediately begins to deteriorate and become congested, it loses its ability to provide the jobs that often were much of the argument for building it in the first place.

Think about the Circle Interchange project the Illinois Department of Transportation is bent on building. For 10 minutes I monitored the “public forum” room at the late June – and final – public meeting about the project to rebuild and increase capacity at the intersection of I-290, I-90/94, and Congress Parkway. I heard seven people speak and at least five of them focused their two minute speeches on the “good jobs” that this project would provide. These are the same “good jobs” that $470 million spent on any other transportation project would generate, like the underfunded but highly beneficial CREATE project that reduces congestion and travel times for freight, Metra, and Amtrak trains in the region.

The Circle Interchange will add an imposing flyover to Greektown and residents and workers on Van Buren Street. 

Building something for jobs is the worst reason to build something. At least with transit (or tollways, for this matter) there is a recurring funding stream, with every use. Oregon is slowly moving in the direction of taxing drivers by mile instead of by gallon, but starting only with electric vehicles. Illinois is issuing bonds for its freeways with the country’s worst credit rating.

Elly’s article had me thinking of other ways cities lose. One of the commenters mentioned there is a loss in property taxes, when properties are demolished to make way for the highway. As Rick Risemberg wrote, “Roads themselves do not pay property tax, of course.” The revenue from those razed properties is eliminated, permanently.

This train flyover represents what the Circle Interchange flyover, over Halsted, will look like. At least this flyover has a revenue stream.

Another way cities lose property tax because of highways is that it makes properties around highways less valuable. It also makes existing, now vacant properties less desirable to developers. So, we have less revenue and then a lowered desire to develop there. Seems like a Catch-22.

However, urban rail stations and bikeways are now known to raise property values and thus government incomes, though this money generated by them is usually not allocated to the infrastructure that created it. (Some places are beginning to use “value capture” mechanisms to do so.)

Risemberg makes sure to point out that gas taxes hardly cover the costs of building highways. I would add that, at least in this state, more and more is being spent on debt service.

And this is all slightly relevant to the article I posted Tuesday on Streetsblog Chicago about transit-oriented development. It’s the third of three articles on the topic based on a report by the Center for Neighborhood Technology that essentially says that Chicagoland, compared to San Francisco, Boston, New York, and Philadelphia, are not experiencing the same benefits of them as adding housing to the transit shed (within 1/2 mile of a train station) and that driving is up in the transit shed of Chicagoland while transportation costs, as a portion of household income, are rising faster in the transit shed than outside. These were surprising to CNT, where the expectation was, in brief, that living near a train station provides more mobility, closer retail and services opportunities, and thus would reduce dependence on expensive automobile ownership.

Current madness of the week: investigating car crashes

Gravity should have prevented this car crash, as would not placing buildings near roadways. But we’ve figured out how to defy gravity. Photo by Katherine Hodges.

“Police closed the street to investigate”.

What a waste of time. The investigation will conclude the same way as any other, with one or more of the following contributing factors: exceeding the speed limit, alcohol, a deficiency in someone’s driving skills or knowledge, or some defect in the road (I’m excluding poor road design as it could almost always be better, designed in such a way to reduce the occurrence of poor quality driving).

The story: a person driving an SUV side swipes another SUV. The driver loses control and then hits the center concrete barrier. The SUV flips over and the driver dies. (Yes, this is in relation to an incident on I-294 in Glenview this weekend.)

We already know how to fix all of these issues.

How I created a map of Illinois Amtrak routes in TileMill in less than 30 minutes

This interactive map was created for a Grid Chicago article to show the cities and Amtrak routes mentioned. Click and drag it around or hover your mouse on the red train station markers. 

Want to create a map like that and publish it on your own website? It’s easy. I’ll show you how to do it in less than 30 minutes. First, download the following files:

All shapefiles are from the United States Department of Transportation, Bureau of Transportation Statistics’s National Transportation Atlas 2012 edition except for Illinois places, which comes from the Census Bureau’s TIGER project.

At the end of this tutorial, you’ll have a good introduction on how to find geographic data, build a map with TileMill, style the map, and publish it for the public. Your map will not look like mine as this tutorial doesn’t describe how to add labels or use the hover/info feature.

Tutorial to make Amtrak Illinois map

  1. Unzip the four ZIP files you downloaded and move their contents into a folder, like /Documents/GIS/Amtrak Illinois/shapefiles. This is your project folder.
  2. Install TileMill and open it.
  3. Set up a project. In the Projects pane, click “New Project”. In the filename field, title it “amtrak_illinois”. Ensure that the checkbox next to “Default data” is checked – this shows a world map and helps you get your bearings (but it’s not absolutely necessary).
  4. Get familiar with TileMill’s layout. Your new project will open with the map on the left side and your Carto style code on the right side. There are four buttons aligning the left edge of your map. From top to bottom they are: Templates, Font list, Carto guide, and Layers.
  5. Add a layer. We’re going to add the four shapefile layers you downloaded. Click the “Layers” button and then click “Add layer”. In the ID field, type in “amtrak_routes”. For Datasource, browse to your project folder and find “amtrak.shp” – this file has the Amtrak route lines. Then click “Done”. Click “Save & Style”.
  6. Style that layer. When you click “Save & Style” after adding a layer, your attention will be called to the Carto style code on the right side of TileMill. A section of code with the “amtrak_routes” #selector will have been inserted with some default colors and styles. If you know CSS, you will be familiar with how to change the Amtrak routes line styles. Change the “line-color” to “#000”. After “line-color”, add a new line and insert “line-opacity: 0.5;”. This will add some transparency to the line. Press the “Save” button above the code.
  7. Add remaining layers. Repeat Step 5 and add 3 more layers: “amtrk_sta.shp” (ID field: “amtrak_stations”), “state.shp” (ID field: “states”), and “tl_2012_17_place.shp” (ID field: “illinois_cities”).
  8. Hide bus stations. The Amtrak stations layer shows bus and ferry stations as part of Amtrak’s Thruway connections. You probably don’t want to show these. In your Carto style code, rename the #selector from “#amtrak_stations” to “#amtrak_stations[STNTYPE=’RAIL’]”. That makes the following style code only apply to stations with the “rail” type. Since there’s no style definition for things that aren’t of that type, they won’t appear.

Prepare your map for uploading

TileMill has many exporting options. You can save it as MBTiles and publish the map for free using MapBox (TileMill’s parent), or you can export it as image files (but it won’t be interactive), or you can display the map using the Leaflet JavaScript map library (which I use for the Chicago Bike Map app). This tutorial will explain how to export MBTiles and upload to MapBox, the server I’m using to display the map at the top of this page.

  1. Change project settings. To upload to MapBox, you’ll have to export your project as MBTiles, a proprietary format. Click the “Export” button above your Carto style code and click “MBTiles”. You’ll be asked to provide a name, description, attribution, and version. Input appropriate text for all but version.
  2. Adjust the zoom levels. Adjust the number of zoom levels you want (the more you have the longer it takes to export and upload your project, and you might exceed MapBox’s free 50 MB account limit). My map has zoom levels 8-11.
  3. Adjust the bounds. You’ll then want to draw your bounds: how much of the map’s geographic extents you want to export. Zoom to a level where you can see the entire state of Illinois in your map. Hold down the Shift key and drag a box around the state, plus a buffer (so viewers don’t fall of your map when they pan to the edges).
  4. Export your map. Click Export and watch the progress! On a four-year-old MacBook it took less than one minute to export the project.
  5. Bring the export to your project folder. When export finishes, click the “Save” button and browse to your project folder. Click the file browser’s save button.
  6. Upload to MapBox. Login to MapBox’s website and click “Upload Layer”. Browse to your project folder, select the .mbtiles folder, and click “Upload file”. Upon a successful upload, your map will display.
  7. Embed it in your website. Click the “Share” button in the upper left corner of your map and copy the embed code. Paste this into the HTML source code of a webpage (or in a WordPress post) and save that (I’m not going to provide instructions on how to do that).

Now you know how to find geographic data, build a custom map using the TileMill application, begin to understand how to style it, and embed your map for the public on a website or blog.

N.B. I was originally going to use QGIS to build a map and then publish a static image before I realized that TileMill + MapBox (the website) can build a map but publish an interactive feature instead of a static image. I’m happy I went that route. However, I did use QGIS to verify the data and even create a new shapefile of just a few of the key train stations on the Lincoln Service (the centerpiece of my Grid Chicago article).

Finding data about traffic and roads in Illinois

There are two good websites that provide information about roads, traffic, and their many attributes. One is provided by the Illinois Department of Transportation (IDOT) called Getting Around Illinois (GAI). The second is the Traffic Count Database System (TCDS).

Both provide Average Daily Traffic (ADT) counts with TCDS making the information easier to find and presents more of it.

The GAI map has an important layer: jurisdiction. With that information you can determine who has “ownership” of a road. Jurisdiction has been an important factor in the nearly year-long delay of the Jackson Boulevard protected bike lane segment from Ogden Avenue to Halsted Street. IDOT has jurisdiction over this segment (which continues east to Lake Shore Drive; the road is also known as Route 66) and is requiring that the Chicago Department of Transportation do more analysis and revise their designs.

If you are looking for ADT counts, I highly recommend TCDS as it uses the more familiar Google Maps and doesn’t require the Microsoft Silverlight plugin (which is slow and often denigrated with poor usability applications).

GAI has truck routes and crash information as well.

Slicing the crash data into interesting visualizations

The Chicago Crash Browser as it looks now. This only exists on my laptop and no place else. I can’t put it online because it’s so inefficient it would kill the server. 

I presented my Chicago Crash Browser to attendees of an OpenGov Hack Night three weeks ago and gathered a lot of feedback and some interest from designers and programmers there.

We collaboratively came up with a new direction: instead of focusing on creating a huge web application that I proposed, we (anyone who wants to help) would start small with a website and a couple of crash data visualizations. The visualizations would serve two purposes:

  • attract attention to the project
  • start building a gallery of data-oriented graphics that describes the breadth and extent of the crash data

Figuring out how many CMAQ projects are for roads

Simplified, the purpose of Congestion Mitigation and Air Quality (CMAQ) grant is to fund projects that reduce congestion and improve air quality. This usually means bicycle, pedestrian, and transit facilities and vehicles. But it also means road projects. Like intersection widening, new signals, changes to signal programming, and “signal interconnect” (timing the signals to cooperate with each other to have some free flowing traffic). It can also mean making grade separations at railroad tracks to eliminate backups when trains cross. However, not everything is infrastructure: there’s also marketing, encouragement, analysis, bike sharing, and education.

In a conversation I was having last night with some transportation advocate friends, one joked that most of CMAQ funds road projects. I agreed (probably because the irony of reducing congestion by making higher capacity roads was funny to me), and we moved on to other topics. I set out verify the actual distribution share for the six-county region in Northeastern Illinois.

I spent almost an hour converting the Chicago Metropolitan Agency for Planning’s CMAQ 2012-2016 projects list from PDF to Excel and then quickly identified every project as being “road” or “not road”. I tallied the amount of proposed CMAQ funding for the projects to get the answer: road projects take up 25.7% of CMAQ funding.

But I can’t stop there! Now that I have CMAP’s data in a spreadsheet, I can get the average of Daily VOC eliminated for road and non-road projects, as well as the estimated cost per VOC kilogram eliminated.

On average, non-road projects have a lower cost per VOC kilogram eliminated ($4,109.37 versus $9,472.90). And non-road projects on average eliminate 19.7 times more kilograms of VOC daily (5.918 kg versus 0.301 kg for road projects).

There are some disclaimers! These are all estimates and not every project has received funding. Also, projects are not selected solely on cost per kilogram of VOC eliminated, or daily VOC eliminated. I’d also like to see estimates on the number of people affected by each project.

You can check my math by downloading my modified projects list (XLS).

The first raised crosswalk I’ve seen in Illinois

The raised crosswalk, a view looking northeast, from the sidewalk. 

Forest Park was a client of mine in 2012 via my work for Active Transportation Alliance; they’re a technical consultant for cities that had grants from the Communities Putting Prevention to Work program. I visited the village with one of their staffers to identify great locations for bike racks (that also included advice on their existing rack inventory, and suggestions for exactly which models to buy).

We would drive around town and then stop and walk a lot. One place where we did a lot of walking was in their downtown, on Madison Street (the same Madison Street as in Chicago). I was pleasantly surprised that their signage reflected the “stop for pedestrians in crosswalk” law, replacing the now-irrelevant “yield for pedestrians in crosswalk” signs. And to top it off, they had talking and lighted signals at some of the crosswalks. I do not support any widespread installation of these: I think they help move our culture in a direction that perpetuates the low respect we have for pedestrians. I believe there are other ways to enforce driver compliance that do not require this kind of equipment.

Forest Park has installed one of those ways: it’s a raised crosswalk (also known as a speed table). It looks like a speed hump, but is much wider, has a flat top, and carries a marked crosswalk (see my article on Grid Chicago “What is an unmarked crosswalk?“). It causes drivers to slow down and has an added – subjective – benefit of intimating that the driver is entering a “protected space”, one for people on foot and that it should be respected. They bring the roadway up to the pedestrian’s level instead of dipping the sidewalk down to the driver’s level.

I don’t know of one in Chicago, but three guys are working to get several installed in a Logan Square traffic circle redesign.

Note: If you are interested in knowing exactly which models of bike racks to buy, learn more at Simple Bike Parking, or contact me directly. I may charge a fee.
