Chicago’s first protected bike lane!

November 5, 2010 / / 0 Comments

UPDATE 04-28-11: I’ve written new articles about this subject. The first is “Put the first cycle track somewhere else.” Then there’s my list of proposed protected bike lane locations.

Chicago just got its first two-way protected bike lane! And all because of a construction detour for the next 17 months!

I’m sort of joking, but sort of not.

This detour from the Lakefront Trail onto a street for 100 feet should give Chicagoans a taste for what a protected bike lane looks like, until April 2012. You can see it’s quite simple to build: shift traffic over, install K-rail concrete barriers, paint a dividing line. But what’s simple to build is not always simple to implement.

But how can we get a real one constructed?

It’s not for lack of demand. But it could be that our demand for a safer bike lane is not well known.

The Chicago Bicycle Program has “proposed” a buffered bike lane on Wells Street (by merely displaying a rendering of it on the backside of a “public meeting” handout). They have no released any further information about this. It would most likely be paid for with Alderman Reilly’s Menu Program funding. (Each alderman gets $1.3 million annually to spend at their discretion and he spent some of it on new bike lanes on Grand Avenue and Illinois Street.)

Contact the Alderman to let him know you want to be able to bike more safely on Wells Street into downtown. And make sure he and the entire Department of Transportation (CDOT; contact Commissioner Bobby Ware) know that people who ride bikes want to be involved in its design; when it comes to informing the public, CDOT has a lot of room for improvement. They could do this by being more timely in providing project updates, like the status of awarding contracts or starting construction on streetscape projects (the website lists the names and locations, but no other information). A major project missing is the Lawrence Avenue streetscape and road diet between Ashland and Western.

Other streets in Chicago are ripe for protected bike lane similar treatment. Can you suggest some places? I’ll keep a list here where we can debate the pros and cons of each location. Through an educated and data-supported campaign, we can advocate for the best locations at which protected bike lanes should be installed.

The Sands Street bikeway becomes protected as you ride closer to the Manhattan Bridge ramp. More photos of biking in New York City.

Protected bike lanes are all the rage in New York City. They have several miles of buffer and barrier separated bike lanes. Portland, Oregon, also has a diversity of protected bikeways. Minneapolis has several miles of off-street trails going to and through neighborhoods (which is why they’re key to the overall network).

HOT lanes and equity

November 4, 2010 / / 0 Comments

The following is extracted from a paper I wrote about I-15 Express Lanes (first phase in 1998) and Managed Lanes (second phase, still under construction). Read the paper, Implementing value pricing on a highway in Southern California.

Equity

Political support is necessary for any value pricing application. Mayor Jan Goldsmith’s story of political maneuverings gave that indication. Implementing value pricing is politically difficult to implement because of the high opposition from the public. This is because of the costs borne by the user. In the case of I-15 Express lanes, all users have the opportunity to use the express lanes if they ride the bus, a motorcycle, ride with a friend or coworker, or drive an exempt low-emission vehicle. There are several tollways around the United States and the world which don’t have a free alternative.

Weinstein and Sciara (2006) suggest that we should avoid defining whether or not the HOT lane concept is equitable, but instead how to address perceived equity issues. The pair have written two reports for planners who will potentially work on value pricing projects. Both reports are cited in this section.

It has been found in the I-15 Express lanes application that users who never use the express lanes, and only use the main lanes (free lanes) occasionally benefit from the lane shift of users to the Express lanes. (Supernak, et al. 1998)

Another concern is that low-income drivers, who cannot afford to pay for the express lanes, will disproportionately benefit high-income drivers (Weinstein and Sciara 2006, 179). This debate between rich and poor drivers has emerged under the title of “Lexus lanes”, but the arguments calling HOT lanes a fast lane for the wealthy are unfounded:

a. Users from all income groups use the express lanes on I-15 and find it fair. The final report’s (Supernak 1999) attitudinal survey found that within all income groups, a majority of respondents approved of the FasTrak tolling of solo drivers in the I-15 HOV lanes.

b. As a mitigation measure to this perception, the Express lanes operation is paid for entirely by toll revenue, which also pays for increased express bus service. Oddly, though, Calfee and Winston (1996) found that the way toll revenues are used does not affect commuters’ willingness to pay (WTP), suggesting that these two mitigation measures do not affect public perception.

How many people ride bikes in Minneapolis and St. Paul compared to Chicago?

November 4, 2010 / / 0 Comments

I applied for a job on Tuesday in the Minneapolis/St. Paul area (Twin Cities).

I had heard that more people, as a percentage of all commuters, commute by bike in Minneapolis and St. Paul than in Chicago and many other cities. If you’ve been reading Steven can plan for a while, you know that I visited Minneapolis in September 2009 and rented a bike for 24 hours.

I used the American FactFinder to get the details. And now I know what I heard is true.

Chicago Minneapolis St. Paul
Workers over 16 1,230,809 190,814 131,798
Ride bikes to work 12,755 6,770 1,567
Bike mode share 1.04% 3.55% 1.19%

Permalink to data results. Data from the 2006-2008 3-year American Community Survey estimates, table B08301.

Knowing these figures led me to question the nothing that Chicago is a bicycle-friendly city. If it’s so friendly to riding a bicycle, how come there aren’t more people riding their bikes to work?

One of my ideas: There are many trails criss-crossing Hennepin and Ramsey Counties that go to and through major neighborhoods and employment centers. These are essentially bike highways without the threat of a automobiles.

Take the helicopter to the airport!

October 29, 2010 / / 0 Comments

If you have a lot of money, you can skip the road traffic and take a helicopter from the Downtown Manhattan Heliport to JFK, LaGuardia, or Newark airports. U.S. Helicopter provides shuttle service for $800 one-way and will get you there in 10 minutes or less. HeliNY Charters charges $1,850.

After the helicopter landed, some people got on and one minute later it took off. While I stood here, a couple helicopters came and went. I took video but I accidentally deleted it later.

3D experimentation to improve pedestrian environment

3D experimentation to improve pedestrian environment from Steven Vance on Vimeo.

The movies aren’t the only place where you’ll see in 3D! Go check out Clark and Deming (about 2540 N Clark Street) in the Lincoln Park neighborhood to see a special pedestrian safety marking on the pavement. They were installed on October 18, 2010.

Designed to increase nighttime visibility

Who’s involved?

  • Chicago Department of Transportation (CDOT)
  • National Highway Traffic Safety Administration (NHTSA)
  • Western Michigan University (WMU)

All three entities are involved in the installation of these optical illusion zig-zag markings.

Between and including years 2005 and 2009, there were at least 2 reports of injuries to people walking and at least 9 reports of collisions involving people riding bikes*. With that data in mind, I’m not sure why this location was selected for a pavement marking whose aim is to improve pedestrian safety. The data do indicate that this intersection has a lot of bicycle-related collisions, much more than I’m seeing for other intersections.

Clark and Deming

Curiously, there are no automobile traffic counts for miles in either direction on Clark Street so one cannot compare the number of collisions at the Clark and Deming intersection with other intersections in town. Out of over 1,200 count locations, Clark Street in Lincoln Park was skipped.

Not really stopping for pedestrians
