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

October Chicago roundup

As much as I try to write about national or international news and events, I can’t keep the Chicago in me suppressed.

Pedestrian safety at Grant Park

Award winning Chicago Tribune writer, Blair Kamin, takes up a cause leading to construction (he won a journalism award from ASCE Wednesday night – not his first engineering award). In 2009, after the Modern Wing at the Art Institute of Chicago opened, along with Renzo Piano’s bridge over Monroe, people started jaywalking more frequently. Blair pointed out how the bridge made the walk across Monroe too distant and inconvenient (agreed) and how the crest of the small hill on Monroe made it so car drivers (naturally driving fast on a four lane street) would not see pedestrians crossing here. CDOT spokesperson Brian Steele said they would investigate it and come up with some options. Eventually some signs and curb cuts were installed, but that wasn’t good enough.

Now, Blair reports, CDOT has installed a pedestrian refuge island and push button-activated flashing lights. Even still, it’s not the best. Blair is advocating for a clear and simple sign that says, according to new state law, “Stop for pedestrians.”

Here’s to hoping that Blair will take up some new causes, like bicycling perhaps. I wrote to him asking him to help me with the Dominick’s bike parking issue, but a well-worded email and letter to the CEO solved that. But I support Blair’s continued case for this street, including making this block car-free. It carries 13,500 cars per day, while Jackson Boulevard to the south carries 7,900. I think the surrounding streets can absorb the additional traffic while some of it will just disappear.

Medill reports that there are now 2,500 vacant condos and apartments (rental condos) downtown. (Does that seem like a lot to you?) The Chicago Spire is the “big deal” building that’s not going to happen.

All that remains is a very large (and deep) hole. Photo by Duane Rapp.

Getting into real estate

I’m loving Curbed Chicago. It’s all about real estate, but it’s not just about transactions or what’s for sale. They post a lot of good links about neighborhood drama and events, and even link back to Steven can plan.

I’m not a “real estate person” but I didn’t know how exciting it can be. And real estate has EVERYTHING to do with transportation. The existing of buildings and the need to go from one to another causes transportation. A UIC professor told the class, “Nowhere does transportation happen for transportation’s sake.” – Professor Joe DiJohn.

And I’ve been dealing with property owners to arrange for the installation of bike parking. The zoning code requires bike parking at new developments but only when car parking is required. I want to change that.

Apple adding Genius Bar capacity to Chicago

Speaking of new developments… The “Apple Store Lincoln Park” opens on Saturday, October 23, 2010, at 10 AM. In the most congested shopping district of Chicago I can think of – it truly sucks to bike on North Avenue through here, but people do it. (North Michigan Avenue is only pedestrian congested – car and bus traffic actually does move most of the time.) There’s no Apple Store parking garage, but I imagine they could have secured the always empty spaces in the parking garage connected to the Borders across the street. Even so, I don’t believe the zoning code would then require bike parking.

I’m hoping that Apple says, “there’s one more thing,” and provides well-designed bike racks (by Jonathan Ive, fingers crossed!) in the new plaza they built between the store and the CTA Red Line station they paid to have renovated.

For a fair division of commuting space

UPDATE: Transportation writer Jon Hilkevitch (“Hilkie”) published an article today about crosswalk enforcement in Chicago based on a new state law the Active Transportation Alliance helped pass that removes ambiguity about what drivers must do when a person wants to cross the street (they must STOP).

But I’m updating this post because he also writes about the crazy pedestrian situation I describe below at Adams and Riverside. I’ve quoted the key parts here:

The situation can be even worse downtown, where a vehicles-versus-pedestrians culture seems to flourish unchecked. Simply walking across Adams Street outside Chicago Union Station at rush hour can feel like you’re taking a big risk, as pedestrians dodge cars, buses and cabs and then must maneuver around the panhandlers and assorted vendors clogging the sidewalks near the curb.

It’s a mystery why such mayhem is tolerated by city or Amtrak police. The highest volume of pedestrian traffic downtown is right there at Adams and the Chicago River outside the station, according to a study conducted for the city.

“The cabdrivers have no concern with pedestrians trying to cross Adams in the crosswalk,” said Richard Sakowski, who commutes downtown daily on Metra from his home in Oswego. “They cut in front of other drivers cursing and yelling, pull from the center lane to the curb and stop in the crosswalk, not caring who they might hit. It is a very dangerous situation that the city does not care about.”

Chicago officials disagree, yet they have for years studied the problems around the downtown commuter rail stations without taking major action.

The city has received more than $10 million in grants to develop an off-street terminal on the south side of Jackson Boulevard just south of Union Station to address traffic safety issues and the crush of taxis and buses vying for limited curb space, according to the Chicago Department of Transportation.

“No timetable yet, but construction could begin in the next few years,” CDOT spokesman Brian Steele said.

Read the full article.


Every weekday afternoon in Chicago, over 100,000 people need to get to Union Station and Ogilvie Transportation Center to get on their Metra trains and go home. If you’re watching them walk, it seems like they don’t have enough room. The multitude of private automobiles with a single occupant and the hundreds of taxicabs also traveling towards these train terminals block the tens of buses that are trying to get commuters to the stations or to their neighborhoods.

Let’s look at Adams Street between Wacker Drive and Riverside Plaza. Riverside Plaza is a pedestrian-only thoroughfare (privately owned) alongside the west bank of the Chicago River and connects both train stations.

People “wait” to cross to the south sidewalk on Adams Street at Wacker Drive because they want to get to the entrance of Union Station. I use wait lightly – they creep out into the street and jog across whenever there’s the slightest opening (against the crosswalk signal).

Those who didn’t cross Adams Street at Wacker Drive now have to cross at Riverside Plaza. Thankfully, there’s a timed signal here for the crosswalk that stops traffic on Adams Street. It doesn’t always work because taxi drivers park their cabs on all segments of Adams Street here, sometimes on top of the crosswalk stripes themselves.

Take a look at the data (from the City of Chicago Traffic Information website):

  • 41,700 pedestrians, walking in both directions, were counted on Adams Street immediately west of Wacker Drive in one 10 hour segment, between 7:45 and 17:45, in 2007.
  • 14,300 vehicles, westbound only, were counted on Adams Street immediately east of Wacker Drive in one 24 hour segment, on September 20, 2006.

For simplicity, divide the number of pedestrians in half to get the actual number of people walking toward the train station in the afternoon. 20,850 commuters walk on Adams Street to get to Union Station. But trains don’t stop at 17:45. There are several more leaving every 5-10 minutes until 19:00. So add a couple more thousand pedestrians. Imagine that a couple hundred of them will be walking in the street because the sidewalk is crammed (I haven’t photographed this yet).

Now for vehicles. We don’t know how many are delivery trucks, taxicabs, or buses were counted. Only two bus routes come through here. (On Madison Street, in front of the Ogilvie Transportation Center, there are twelve bus routes and fewer walkers.) Some of the vehicles are turning right or left onto Wacker, so we can probably decrease the quantity that’s actually passing by the same count location as the pedestrian count.

Spatial mismatch

So now we know a little bit more about how many people, and by what mode, travel on Adams Street between Wacker Drive and Riverside Plaza. Walking commuters have little room (so little that some choose to walk in the street) on their standard 10-14 feet wide sidewalks and motorized vehicles get lots of room in four travel lanes. Then, the vehicles that achieve the highest efficiency and economic productivity are delayed by the congestion, in part caused by the least efficient vehicles.

Is the space divided fairly? What should change? What examples of “transportation spatial mismatch” can you give for where you live?

Is Chicago ready for Tokyo-inspired elevated pedestrian bridges at intersections? Las Vegas has several of these, as well as every Asian city with a few million residents. I first brought this up in the post, World photographic tour. Photo by Yuzi Kanazawa.

Bikes and streetcar tracks

UPDATE 12-11-10: Someone recently searched for rubber in tracks and I wanted to provide some additional resources on the topic of protecting people who ride bikes from the dangers of open streetcar tracks. It is possible, in some situations, to fill the track flangeway (where the wheel goes) with rubber that the train depresses as it rolls over but people riding bikes ride over a level surface. Resource one input from people around the world, and two, a column in The Oregonian newspaper of Portland.

UPDATE 12-14-10: BikePortland has a story about an activism and advocacy group (AROW) that will demand better accommodations for bicycling around new streetcar tracks in Portland, Oregon.

UPDATE 08-13-13: Zurich, Switzerland, will be testing a flangeway filler on their tram tracks. I believe this will be the first transit system to test the rubber fill. 

Bicycle riders in Seattle are suing the City of Seattle for not providing enough warnings about streetcar tracks in the South Lake Union neighborhood. They allege the City installed warning signs only after several bike-track crashes.

Photo: A sign on Stewart Street in Seattle, Washington, advises bicycle riders to use EXTREME CAUTION when crossing the streetcar tracks. These signs are coming under question in a lawsuit this week.

Mixing bicycles and transit is one of the most sensible matches of transportation modes. The Federal Transit Administration has been promoting a positive union since at least 1999 (see the booklet they produced). The publication includes case studies and good examples of integration, including a story about how King County Metro (the primary bus operator in Seattle) installed bike racks on its buses in 1993, following the footsteps of Phoenix.

Photo: A resident rides their bike on the street while a Portland Streetcar rolls by.

So how is it now, 17 years later, we’re still deliberating how streetcars, light rails, and bicycles can safely share the road? Why this is a problem:

  • People are getting hurt. Concerns about personal safety demotivate people to ride their bikes.
  • The Federal government is funding many new streetcar projects across the country, including in Tucson, Arizona, two hours south of Phoenix, which has its own light rail system.
  • Bicycle riders have been navigating tram and streetcar tracks in Europe for 100 years. What knowledge can European riders and planners share with us?

Photo: A rubber-filled flangeway in the gap between rail and deck on the Cherry Avenue Bridge in Chicago, Illinois. This bridge serves a 1-car train a few times a week.

Could a rubber-filled flangeway be used on a medium-frequency streetcar line?

Street safety is also a user issue

Street safety is based in part on the right infrastructure design, but also user behavior.

Keep off the tracks. Sometimes a train seems to appear out of nowhere (this seems to be especially true for motorists). I hope Operation Lifesaver is still being taught in schools. I remember someone coming to my school to talk about train safety.

I think trains to many Americans are still a new concept. To best understand what I mean, read the newspaper articles in the two months following any new light rail opening in the United States. There’s a collision every week. Unlike Europe, we ripped out all of our streetcars, light rail, and trams, and we’re still in the beginning stages of returning to rail.

Bicycling and buses: Their large size and unwieldy maneuvering can make it harder to predict movements. Don’t play leapfrog and wait for the bus operator to make the first move (video) – the second move is now yours and safer.

Recognize stop bars, crosswalks, signals. The stop bar isn’t at the bicyclist’s position for a very good reason.
