Can we use location-based services to make urban planning “rise”?

Facebook launched a feature called Places that allows its users to “check in” to Places and to see where their friends are. People can also see where the most popular venue is at any given time (provided they have friends there).

SeeClickFix has mobile apps (and a website) that enables users (in participating locales) to report issues (like graffiti and potholes) in their neighborhoods.

Augmented reality apps for smartphones overlay the virtual world (of yellow pages and restaurant reviews) on the physical world depending on where you point your phone’s camera.

Is there something (an app, a concept, a teaching) that we can develop that uses these apps or the same technology to raise awareness of “urban planning” in all of our cities’ citizens? Such a scheme would attempt to educate and involve more people into the city’s social, cultural and built environments, the urban fabric (buzzword alert!), as well as the history of their surroundings.

Possible scenarios

1. While riding the train through a neighborhood, the new location-based service that encompasses everything about urban planning might aggregate information relevant to the location and activity. Perhaps the application would display to the user information about the history of this particular elevated train’s construction on this branch as well as pull up information on upcoming schedule changes. Lastly, the transit operator may ask the user to take a survey about this particular trip, looking for information on how the user accessed the station (via bike, walking, car, or bus?).

2. My friend Brandon Souba created a proof-of-concept app called Handshake that tells you about nearby app users with similar interests. But this hardly raises civic or urban awareness. Maybe non-profit organizations who need volunteers could create profiles in Handshake and when you’re near a staff member or the headquarters, your phone alerts you to a possible volunteer opportunity.

3. What are your ideas?

I think I finally figured out the purpose of making plans

No, not plans with friends for dinner at Ian’s Pizza in Wrigleyville (which was great last night, by the way).

I graduated in May 2010 and I’m just now figuring out why we should make plans. What did I come up with?

Plans are to give a basis for the future so that the future is shaped from what people collectively need and want. They keep you on track so you focus on what’s most important and not the things that will derail the path to the plan’s stated goals.

(You can quote me on that. But I wouldn’t rely on that statement to stay the same – it’s still a work in progress.)

For example, you go out and survey the bike parking situation at all transit stations in your city. You collect data on how many bike parking spaces are available, how many bikes are present (both on bike racks and other objects), and bike rack type.

You then gather information like ridership, access mode, and surrounding residential density. From this you can list the stations in order of which ones need attention now, which ones need attention later, and which ones won’t need attention. Talking to people who work at the stations, who use the stations, and others will help you fine tune the ranking.

That’s the plan. The plan might also include narratives about the rationale for having high quality, sheltered, upgraded, or copious bike parking at transit stations (hit up the Federal Transit Administration for that).

Then the plan sits. Two years later, someone reads the plan and decides to apply for funding to build bike parking shelters at the transit stations in most need.

What stations are those? Oh, the plan tells us.

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.

Philadelphia Water Department moves away from Deep Tunnel-style water management

West North points out that instead of spending $8 billion to build new sewage holding tanks throughout the city, the Philadelphia Water Department plans to conver impervious surfaces to pervious, natural surfaces. The American Society of Landscape Architects has more information on The Dirt:

The green infrastructure proposal would turn 1/3 of the city’s impervious asphalt surface, or 4,000 acres, into absorptive green spaces. The goal is to move from grey to green infrastructure. Grey infrastructure includes “man-made single purpose systems.” Green infrastructure is defined as “man-made structures that mimic natural systems.” As an example, networks of man-made wetlands, restored flood plains, or infiltration basins would all qualify as green infrastructure. The benefits of such systems include: evaporation, transpiration, enhanced water quality, reduced erosion / sedimentation, and restoration. Some grey / green infrastructure feature integrated systems that create hybrid detention ponds or holding tanks, which are designed to slow water’s release into stormwater management systems.

And, like Portland, Philadelphia is accomplishing more than just better stormwater management.

…the city is calling for a triple-bottom line approach, aiming for: more green spaces, improved public health, and more green jobs. [The Dirt]

Portland is building “Green Streets” that combine bicycle facilities with green infrastructure like bioswales inside curb extensions. This plan did not arise perhaps as altruistically as Philly’s (actually with a little controversy), but more as a way to build bicycle facilities with bioswale funding.

Meanwhile, the Deep Tunnel system in Chicago continues to expand. But it’s not all bad. The City of Chicago will showcase green infrastructure in a new streetscape in the Pilsen neighborhood.

Tribune points out why we need something better than Deep Tunnel

60 billion gallons of rain fell on Cook County on Friday night, according to the Metropolitan Water Reclamation District’s (MWRD) president Terrence O’Brien.

That’s enough to fill 1.2 billion of these Suncast rain barrels*. The rain was too much for the Deep Tunnel – the underground network of  water reservoirs. They hold water runoff during storms before it goes to the water treatment plant for cleaning, after which it will flow into one of the water channels in and around Chicago. But the storms on Friday were too much – the MWRD had to release sewage into Lake Michigan because the reservoirs were full.

This in turn forced the Chicago Park District to close the beaches.

“All 109 miles of the Deep Tunnel system were filled during the storm, O’Brien said.”

We find ourselves in a situation similar to that of traffic congestion. Building new and wider roads doesn’t relieve traffic congestion. The same might be true for Deep Tunnel construction. Longer and wider tubes won’t reduce our water usage or how much stormwater is directed to the sewers (Chicago has a combined sewer, draining sewage from buildings and stormwater from the street). The Chicago Tribune article doesn’t exactly point out the solution, and it only hints at the problem: We get more water in our tunnel than we can handle.

Chicago Harbor Lock

The water at Chicago’s magnificent beaches could have been contaminated so the Park District closed swimming at ALL beaches until at least Monday morning. Photo by Norma Fernandez.

Chicagoland needs a better stormwater management plan that incorporates sustainable best practices. We can start by encouraging landscaping that absorbs stormwater instead of acting like a slope towards the nearest drain. New streetscape projects can have bioswale planters. What other ideas are there to reduce the amount of runoff that has to be stored in hundreds of underground tunnels?

*The MWRD sells rain barrels to the public online for pickup. Rain barrels are just one part of a multi-pronged solution to stormwater management.
