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.

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.

What the Census says about bicycle commuting

UPDATE 11-08-10: I wrote a post comparing the commuting statistics between Chicago, Minneapolis, and St. Paul.

UPDATE 02-12-11: Added 2009 data.

Prompted by this entry on BikePortland about the rise of bicycle commuting and the bicycle mode share in Portland, Oregon, I decided to research what the American Community Survey says about the mode share of bicycles as part of commuting where I live: Chicago. I’ll also post bicycle’s share of commuting for other locales, as well.

Some definitions, first:

  • Commuting means travel to and from work – the Census Bureau calls this “MEANS OF TRANSPORTATION TO WORK.” The Census Bureau does not collect information on travel to shopping, medical services, and other places in the decennial census or the yearly American Community Survey (which will supposedly replace the decennial census).
  • Block means the smallest area for which the Census Bureau reports statistics. Any smaller and the possibility that someone could personally identify you from the responses increases. Find your block. The American Community Survey reports information for much larger areas: In some cases, researchers can only select data at the county level. The Census Bureau provides information for the City of Chicago and other municipal divisions of many counties in Illinois.
  • Subject definitions. These describe the question asked to participants and include clarifying information in the case the participant doesn’t understand the question, or their answer is complex. Download the subject definitions for the 2008 American Community Survey.
  • Margin of error (MOE) means the high and low end of confidence. Read more about margin of error on the Census Bureau’s website.

For the American Community Survey, I found table S0801, Commuting Characteristics by Sex. In the decennial census, I found table  P30. MEANS OF TRANSPORTATION TO WORK FOR WORKERS 16 YEARS AND OVER. If you want to check my research, look for these tables of sample data.

Chicago:
Margin of error for male and female categories varied. Combined always reported 0.2%.

  • 2009 – 1.1% travel to work by bicycle. 1.8% male (MOE: 0.3%), 0.4% female (MOE: 0.1%). Workers over 16: 1,271,744. Permalink.
  • 2008 – 1.0% travel to work by bicycle. 1.5% male (MOE: 0.3%), 0.5% female (MOE: 0.2%). Workers over 16: 1,260,741. Permalink.
  • 2007 – 1.1% travel to work by bicycle. 1.4% male (MOE: 0.3%), 0.7% female (MOE: 0.2%). Workers over 16: 1,230,933. Permalink.
  • 2006 – 0.9% travel to work by bicycle. 1.2% male (MOE: 0.3%), 0.7% female (MOE: 0.2%). Workers over 16: 1,209,122. Permalink.
  • 2005 – 0.7% travel to work by bicycle. 0.9% male (MOE: 0.1%), 0.4% female (MOE: 0.1%). Workers over 16: 1,162,550. Permalink.

United States:
Margin of error happened to be the same for each reported category (combined, male, female).

  • 2009 – 0.6% travel to work by bicycle. 0.8% male, 0.3% female. MOE: 0.1%. Workers over 16: 138,591,804 (decrease). Permalink.
  • 2008 – 0.5% travel to work by bicycle. 0.8% male, 0.3% female. MOE: 0.1%. Workers over 16: 143,995,967. Permalink.
  • 2007 – 0.5% travel to work by bicycle. 0.7% male, 0.2% female. MOE: 0.1%. Workers over 16: 139,259,684. Permalink.
  • 2006 – 0.5% travel to work by bicycle. 0.6% male, 0.2% female. MOE: 0.1%. Workers over 16: 138,265,905. Permalink.
  • 2005 – 0.4% travel to work by bicycle. 0.6% male, 0.2% female. MOE: 0.1%. Workers over 16: 133,091,043. Permalink.

Read the BikePortland article if you want to know that Portland has a higher share of commuters traveling by bicycle than Chicago has.

And what about my block? As I mentioned above, we can only find information at the block group level in the decennial census. I live in Block Group 1 of Census Tract 6009 in Chicago, Illinois. I didn’t live here in 2000, though, the last time the decennial census occurred. Back then, out of 168 workers over 16, 4 of them rode their bikes to work! That equals .024% of the worker population in my block group. Oddly, though, the Census Bureau reported 946 people living in this Block Group. Looking at table P8 (Sex By Age), I see that 674 have at least 16 years of age. 178 people have at least 55 years. Does this mean a lot of people in the Block Group didn’t work at the time of the survey in 2000? I don’t know. Permalink to data.

By far, though, driving alone won as the most popular way to get to work: 71.423% of the worker population.
