Road pricing is more fair than other funding schemes

August 13, 2010 / / 0 Comments

I’ve written several papers on congestion and road pricing*. The most common type seen in the United States is HOT (high occupancy tolling) lanes. This is where drivers can pay to use uncongested lanes; drivers who carpool may use the lane for free or at a discount. Transit buses can always use the lane for free.

From the University of California Transportation Center comes new research on paying for roads with congestion versus paying for roads with sales taxes and their respective burden on poor residents.

Will research show that more people will benefit from paying sales tax to support a transit system than from paying (all kinds of) taxes to support a highway?

Their finding is that funding transportation with sales tax is less fair than funding with congestion pricing. In the latest issue of Access, Lisa Schweitzer and Brian Taylor write:

This analysis has focused on one side of the ledger: the question of who pays. But transportation systems have both costs and benefits. Indeed, the access benefits of travel are transportation’s raison d’être. So while regressivity can be viewed as a cost of road pricing (and of most other ways of paying for roads), pricing confers transportation benefits that other transportation finance mechanisms do not. Tolls and taxes can both pay to build a road. But congestion pricing can also reduce traffic delays, fuel consumption, and vehicle emissions, often to a surprising degree. Sales tax finance for transportation, by comparison, does none of these things.

I think the appropriate direction of this research should next discuss and examine the fairness of using sales taxes to provide operational and capital funding for transit. In Chicagoland, the Regional Transportation Authority is partially supported by a local sales tax. While sales tax financing for road building may not reduce traffic delays, fuel consumption, or vehicle emissions, supporting a reliable, robust and expansive transit network can do all of those things by reducing the number of single occupant vehicles on the road.

*Here’s one I’ve written: Implementing value pricing on a highway in Southern California, which I excerpted in HOT lanes and equity.

Video: Bicycling next to Phoenix Valley light rail train

December 23, 2009 / / 0 Comments

UPDATE: View overhead photos of all of the bicycling treatments on Jefferson and Washington streets (the one-way couplet) between 7th and 24th Streets in Phoenix, Arizona, courtesy of the Coalition of Arizona Bicyclists.

My dad and I rode our bikes in the inside left-hand bike lane on eastbound, one-way, Washington Street in Phoenix, Arizona (purely to take this video).

The left-hand travel lane is for home and business access while the one-way light rail track (and its stations) run in the middle of the street. The lane is here so that there aren’t gobs of driveways and track crossings – it’s a safety feature. I think the bike lane is here instead of on the right side of the street (and next to the curb) because less traffic drives here. Also, there are few opportunities for right turns in front of the bicyclists.

Eventually, though, going east, the bike lane moves over to the right side through the use of a “perpendicular bike lane” adjacent to a crosswalk in a signalized intersection. The perpendicular bike lane looks like a bike box. This happens at 24th Street because the left-hand access lane disappears and Jefferson Street merges into Washington Street, between 25th and 27th Streets, which becomes a two-way street with the light rail tracks dividing the travel directions. (I would add links to Google Maps, but the imagery is outdated and doesn’t show the 1-year old train line; it does show some construction.)

I would call all of these features innovative designs and good solutions. I think tomorrow I will ride the area again (probably alone) to get a better feel for how it works and how safe bicyclists would perceive the design.

The video is sped up by 20% to be less droll. The audio drops out a few times because I was talking (giving my dad directions like a movie producer), but you can still hear the electronic sounds of the train as it approaches and departs the station. I didn’t have my camera’s bike mount so I held it in my hand. I want to come back to take photos instead of video. It was fun to make this video!

The snow debate: Who should clear sidewalks?

December 23, 2009 / / 0 Comments

A couple of days ago (I think it was Friday night, December 18, 2009), a storm dumped several feet of snow in the northeast United States, covering New York City, Washington, D.C., and Philadelphia, Pennsylvania. The storm was so eventful that Metro (Washington, D.C.) stored many of its trains in the subway tunnels to avoid getting them covered in heavy snow, and applied “heater tape” to the third rails to keep them from getting new ice after two passes from plows and deicing trains. [This information comes from the linked Metro press release on December 19, 2009.]

Now Streetsblog NYC is hosting the debate about snow removal from sidewalks. Why doesn’t anyone do it, and who should do it? Images of unplowed sidewalks and pedestrians walking in clean and clear streets bring up issues about priorities in street design and maintenance.

Many municipalities have ordinances requiring the property owner to remove snow from the sidewalk (Chicago even specifies a time frame in which the work must be completed; at my last apartment, I shoveled the snow from the sidewalk and porches for a deduction in rent). Many people report how these laws pass through the winter without enforcement.

My bike waits for me on unplowed sidewalk in front of my school. I live in Chicago, Illinois, not the east coast.

A plow removes snow from a bike lane in Copenhagen, Denmark. Is this something we can bring to our bike lanes and sidewalks in the United States?

Motoring is triple threat to bicycling and the environment

November 13, 2009 / / 0 Comments

Location: Northwest corner of Clark Street and Congress Parkway.

This photo shows the damage that automobiles inflict on our cities, environment, and, closest to my heart, bikes and bike parking.

An errant motorist jumped the curb and crashed first into the tree, then the bike rack, and finally the bike parked here. The LaSalle Blue Line station entrance is just steps away (in the background). Imagine the fate of a bicyclist who might have been locking their red Schwinn road bike to the bike rack only to find a 2-ton metal box hurtling in their direction. This photo makes clear how driving is a threat to so many aspects of our streets.

The collision had a direct monetary cost. The city will most likely pick up the tab for everything except replacing the bike. Here’s what I surmise from the photographed scene:

  • Tree removal and replacement: >$1,000
  • Bike rack removal and replacement: $450 ($300 for a new one, $150 to remove)
  • Vintage Schwinn: $200
  • Bike removal: $50
  • Cleanup: $150
  • Total: At least $1,850

Please drive carefully. Send me your photos of the automobile imposition – reader updates are here. But wait, I’ve encountered this again and again:

Location: Northwest corner of Elton Avenue and Cicero Avenue.

Location: Northwest corner of Lawrence Avenue and Kostner Avenue in front of Chicago Public Library, Mayfair branch.

UPDATE: Thanks for the mention, BikePortland.

Pollution fighting bike lane, coming soon to Pilsen

October 27, 2009 / / 0 Comments

Rendering of the project by CDOT. See all photos about this project.

A planner from the Streetscape and Sustainable Design Program in the Chicago Department of Transportation (CDOT) came to speak to my Sustainable Development Techniques class at UIC about adding “green” to urban design.

Among other topics, he talked about CDOT’s streetscape project for Cermak and Blue Island in Pilsen, a near southwest side neighborhood a couple miles outside of downtown Chicago. The project, like all streetscapes, is one of economic development. But this project is unique in that the goal was to look at every element and make each as green and sustainable as possible.

You can read about the project through the Program’s presentation here (Flash slideshow). Please note there are many versions of the same presentation on the web and each my be different depending on their intended audience.

I will be discussing a single showcase element from the project: A bike lane on Blue Island between Ashland and Western where currently one does not exist. The bike lane and the adjacent parking lane (on the bike lane’s right side, as normal in Chicago) will be constructed with permeable pavers mixed with smog eating concrete. Wait? Smog eating concrete? Keep reading!

The bike lane will begin at Ashland/Cermak/Blue Island, a well-traveled intersection for heavy trucks, three bus routes, and many passenger cars. The bike lane will connect Pilsen to Little Village and extend the existing bike lane on Blue Island in Pilsen’s central shopping area. This segment is also a designated truck route and to safely accommodate the parking lane, bike lane, and travel lane, the road will be widened by reducing the width of the sidewalks. The sidewalks here are 20 feet wide, double the standard width, and four times wider than sidewalks in many parts of Chicago. There’s very low pedestrian volume here and very little residential use so the plan is to have 8 foot wide sidewalks, and a 5.5 foot planter, breaking occasionally for bus stop shelters.

The bike lane will be 5 feet wide (including striping) and the parking lane will be 8 feet wide. The novel part of the two lanes is that they will be made with permeable pavers.

This will be the first paver bike lane in the City of Chicago. The blocks will be oriented so that bicyclists feel the least amount of bumps and won’t get their tire stuck in a groove that could harm.

The smog eating concrete’s trade name is TX Active, invented by Italcementi Group, a large, multinational corporation founded and based in Italy. Since the original installation of TX Active cement on the Dives in Misericordia Church in Rome (designed by Richard Meier), Italcementi has developed two lines of photocatalytic cement, only one of which reduces pollutants in the area (TX Arca). The other cement is for architectural uses helps keep the concrete surface clean from dirt and particulate matter.

CDOT will use the second line, TX Aria, in the top half inch of the pavers. The company has tested the product to demonstrate its effectiveness at reducing the presence of Nitrogen Oxides (commonly written as NOx, a family of toxic substances emitted by internal combustion engines) and published its laboratory results in an easy to follow report on its website (PDF). The technical report goes into more details and explains how the process works (through photocatalysis) and what substances their product can be designed to diminish. The technical report is unclear on whether or not all forms of the TX Active product abate all substances. It may be that the maker only tested its effects on Nitrogen Oxides levels.

I look forward to watching the construction progress and to breathing the cleaner air while bicycling to a new destination in Pilsen.
