The blizzard’s calming effect

February 7, 2011 / / 0 Comments

Last Wednesday night, after the blizzard had stopped and the city had plowed arterial roads, I took two buses to Pilsen in 36 minutes. Transit buses have an average speed lower than bicycling and I don’t think I could have biked there in 36 minutes. (I didn’t want to bike because I didn’t know the condition of roads from my new place in Avondale to dinner in Pilsen.)

I credit the speedy journey to the complete lack of cars on the road and the few people wanting to go out on Wednesday, as well as ride the bus.

The blizzard gave Chicagoans a break. Hundreds of thousands of workers stayed home on Wednesday. Thousands more got the day off on Thursday. Car traffic remained light through Friday and the Chicago Transit Authority trains and buses were packed on Thursday (partially because of mechanical problems on the Blue Line but also because of new riders who couldn’t drive or carpool).

Many people took walking tours around their parks and neighborhoods, or went to see the calamity of Lake Shore Drive. Flickr is loaded with the explorers’ photos. Check out 2,000+ labeled “snomg chicago.”

The blizzard’s effect on traffic and roads

The snow plows inadvertently created a curb extension at the main intersection in Wicker Park, often used as part of a traffic calming project. This was gone on Saturday, but in addition to its removal, the entire corner sidewalk was cleared.

A lot of bike lanes are buried right now and people riding bikes are riding in the middle shared lanes, further calming traffic. I’m not sure how long the civility I noticed between drivers and bicyclists last week will last, even as bike lanes remain “closed” or have been illegally co-opted into backup parking lanes. See next photo.

These drivers have illegally parked their cars in the bike lane. The municipal code does not offer any relevant (i.e. snow-related) exemptions for parking or standing in bike lanes.

Riding and driving through town has been interesting. There’s no room for people riding bikes to share the lane with drivers side by side, so they must share it front to back.

Humboldt Park “do over”

January 27, 2011 / / 0 Comments

Read the story below and the final paragraph to fully understand this drawing.

If you, like Alderman Roberto Maldonado (26th Ward), received complaints about speeding traffic and difficulty crossing Humboldt Drive, how would you respond?

The Chicago Department of Transportation (CDOT) responded by temporarily changing “the four-lane street into two travel lanes with a center lane used as a combination left-turn lane and pedestrian refuge area, using orange traffic barrels to keep moving cars out of the center lane.” (All quotes from Vote With Your Feet / Time Out Chicago, by John Greenfield.)

Narrowing the lane could reduce automobile speed and the refuge island should make it easier to cross the street, even if it has to be done in two movements. “After CDOT analyzes the effects on traffic speed and behavior, [CDOT spokesperson Brian] Steele says, the changes may become permanent next year.”

But bicyclists are not considered in this installation. That seems to be by design.

“He [Alderman Maldonado] told me that he has no intention of adding a bicycle lane or any other accouterments on that stretch because ‘the road is too dangerous for pedestrians,’” she says. Lottes recently posted on the local bike website thechainlink.org, asking members to lobby Maldonado for bike lanes on Humboldt. “To me the road seems too dangerous for pedestrians because there are no sidewalks, crosswalks or bike lanes.”

A local resident, Gin, asked me if I could draw up something for Humboldt Drive and I drew what you saw above. I based it on a bike lane design I saw in New York City: two-way, barrier protected (see photo below). The intersections between the bike lane and the other lanes will need special care – I don’t have any expertise there, but I know some people in Portland and New York City who do.

What else might you propose? Here’s a map of the park (centered on where I drew the bike lane), and a street view of the location.

Mayoral candidate Miguel del Valle’s view on sustainable transportation

January 15, 2011 / / 0 Comments

Active Transportation Alliance executive director Ron Burke wrote a blog on Friday (January 14, 2011) about his meeting with mayoral candidate Miguel del Valle (the current Chicago City Clerk).

Despite those caveats, he talked about his fondness for bicycling, its importance to the city and how his son is an avid cyclist. He also talked about one of the reasons he opposes the city’s parking meter contract, and has joined a lawsuit to overturn it: It’s because it limits the city’s ability to take away parking spaces for building bike lanes and sidewalks, and slowing traffic. We [Active Trans] share these concerns! [emphasis mine]

This meshes with a report Active Transportation Alliance released in June 2009 but recalled parts of the report five months later. But the message that report gave us remains true today and Miguel del Valle is repeating it. Margo O’Hare wrote announcing the report:

This limits any potential projects that use streets with metered spaces: bus rapid transit, bicycle lanes, street festivals, sidewalk expansion, streetscaping, pedestrian bulb-outs, loading zones, rush hour parking control, mid-block crossing, and temporary open spaces. The City’s ability to use streets in fresh, people-centric ways is now dictated, controlled and limited by the arrangements and penalties within the parking meters lease.

In November 2009, the Chicago Reader reported how the Active Transportation Alliance was going to release a new version of the report. Mick Dumke wrote:

Yet Monday night the Active Transportation Alliance inducted Mayor Daley into its “hall of fame,” and the group will soon release a new version of the report—screened beforehand by city officials—that will recant many of the criticisms it made in June.

Said Rob Sadowsky, “On behalf of the Active Transportation Alliance, I would like to simply state that we should not have published this report. I am embarrassed that it not only contains factual errors, but that it also paints an incorrect interpretation of the lease’s overall goals.” Regardless of any errors or misinterpretations, the original report’s essence will prove to be correct and foretelling: The City lost control over its own streets, the most basic and widely used element of neighborhoods and our  transportation system.

I look forward to voting for a mayoral candidate who opposes Mayor Richard M. Daley’s parking meter “lockout” with Morgan Stanley and other investors.

Along with the parking meter lease came the removal of approximately 30,000 high-quality bike parking spaces.

I’ve written a few times about the mayoral election, including the two forums I’ve been to (one at UIC about the economy and higher education, and the second about public school systems at the Chicago Teachers Union).

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.

3D experimentation to improve pedestrian environment

October 28, 2010 / / 0 Comments

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
