Figuring out how many CMAQ projects are for roads

March 19, 2012 / / 0 Comments

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.

Google Maps is annoying sometimes

March 11, 2012 / / 0 Comments

I was looking up traffic counts on the Chicago Traffic Tracker website and saw that the Halsted Street bridge over the Chicago River just north of Chicago Avenue is missing. It’s shown as a gray line with the text “Halsted Street (planned)”.

This is not the most accurate message. The west side sidewalk is still open to foot and bicycle transportation, as I pointed out in my Grid Chicago article, The Halsted Passage. I wonder how it got in there.

I’ll report this as a problem, but I’m wary of it actually being updated to show that people on foot can still cross the river here. I’ve used Google Maps’s Map Maker tool once, and I didn’t like the experience. My correctly-made adjustment of a street was questioned and I was asked to revert my change. I refused and eventually my change was approved… because it was correct. I guess that someone used Map Maker to (incorrectly) modify the street at this part. This street segment in Map Maker should be designated something close to a “pedestrian walkway” instead of a bridge for automobile, bus, and bicycle traffic.

The Google Maps walking directions for walking from Division Street to Chicago Avenue don’t show the option of using the sidewalk, which is entirely possible (I did it again this week).

Dealing with the four-wheeled foe

February 23, 2012 / / 0 Comments

My comment on the Streetfilms post. 

First, Streetfilms’s Clarence Eckerson posts a video showing Mazda’s support for the movie “Lorax”, which is based on the Dr. Seuss book about destroying the environment.

Then, I commented on Bikes Belong’s partnership with Volkswagen that was announced almost a month ago but I had just found the news yesterday.

It’s about as crappy as Bikes Belong partnering with Volkswagen.
In January 2012 they announced a “two-year partnership to help develop biking-friendly communities, foster healthy lifestyles and create a cleaner environment.”
I thought Volkswagen’s job was to market its cars, but it seems now it will market its goodwill which must have a calculable impact on increased car sales.

Bike Portland and road.cc both wrote about it. One commenter, Hart Noecker, wrote on Bike Portland:

Agreed. They recognize their oncoming irrelevance and are trying to re-image their brand while still promoting unsustainable automobiles that incentivize McStripmall sprawl.

And “9watts” replied:

As someone who has long felt that VW offered some of the most fuel efficient cars available, and was therefore to be lauded, patronized, etc. I’m inclined to agree with Hart. VW is really good at selling cars, and their commitment to fuel economy (which is a far cry from what we need now: a phaseout of car-dom, which isn’t going to come from the car industry anymore than a phaseout of coal consumption is going to come from the electric utilities) is only skin deep.

Crumbs for bikes, and a slick PR move that might even help them sell more cars. Never underestimate the middle class’s eagerness to swallow feel-good nostrums.

Today it seems the pact is getting attention again, brought to the forefront by the Mazda + Lorax (Universal films) deal – at least among a few people I follow on Twitter. Hopefully for its inanity. Car manufacturers, the bull in the china shop as Mikael of Copenhagenize talks about it, have been shutting down bicycles as a mode of transportation for decades. They’ve even thrown support behind making jaywalking criminal.

The Volkswagen deal with Bikes Belong is nothing more than buying goodwill. If there was a store for companies looking to improve their environmentally friendly image, partnerships with cycling advocacy organizations would be in aisle one.

As they are a company interested in making money by selling cars, I’d like someone to help me understand if there are any other reasons they should promote cycling (which they admit reduces congestion and lowers a traveler’s impact on the environment). Maybe they want to start selling bikes?

Car culture is carnage culture. The way out is a balanced transportation system that focuses the highest investments into sustainable and efficient modes, and one that educates system users on the costs and benefits of each mode, for every trip. Photo by ATOMIC Hot Links.

How high (and low) expectations can make traffic safer

February 20, 2012 / / 0 Comments

I have low expectations of fellow Chicagoans who are moving their vehicles on the same roads I cycle on. I expect that every door will fling open in my path, causing me to be doored. I also expect to be cut off at any moment, and especially in certain places like at intersections (where the majority of crashes occur), bus stops, or in places with lots of parallel parking activity. Because of these expectations I feel that my journeys have been pretty safe. My low expectations cause me to ride slower, ride out of the door zone, and pay attention to everyone’s maneuvers.

This is another post inspired by Traffic: Why we drive the way we do (and what it says about us) by Tom Vanderbilt. From page 227 of “Traffic”, about expectations :

Max Hall, a physics teacher in Massachusetts who often rides his collection of classic Vespas and Lambrettas in Rome, says that he finds it safer to ride in Rome than in Boston. Not only are American drivers unfamiliar with scooters, he maintains, but they resent being passed by them: “In Rome car and truck divers ‘know’ they are expect not to make sudden moves in traffic for fear of surprising, and hurting, two-wheeler drivers. And two-wheeler drivers drive, by and large, expecting not to be cut off.”

The scooter drivers have high expectations, and it seems that they’re being met.

This all plays nicely with the “safety in numbers” theory about cycling: the more people who are riding bicycles, the more visible bicycling is, and the more aware a driver will be around people who are bicycling, and the more they will expect someone on a bicycle. Awareness means caution.

It’s difficult to gauge the safety of cycling in Chicago as we’ve no exposure rate: we don’t know how many people are cycling how many miles (nor where).

A cyclist waits for the light to change at Milwaukee Avenue and Ashland Avenue. 

Exposure rate

Exposure rate in the sense I’m using it here means the number of times someone is in a crash or injury for each mile they ride. We know how many crashes and injuries are reported each year (in the Illinois Motorist Crash reports), but we don’t know how many miles people ride (neither individually nor an estimated average).

There was a limited household survey of Cook County residents in 2008 from CMAP, called Travel Tracker, that collected trip distance information for all trips members of a household made on all trip modes – I haven’t looked into this yet.

It would be highly useful if the Chicago Department of Transportation conducted ridership counts at the 10 intersections with the highest crash rates. And if the 10 intersections changed the following year, the new intersections would just be added to the initial 10 to track the changes of the initial 10. This would be one step closer to being able to determine a “crash rate” for each intersection.
