Trying out uDig, a free, multi-platform GIS application

ArcGIS is the standard in geographic information system applications. I don’t like that it’s expensive, unwieldy to install and update, and its user interface is stymying and slow*. I also use Mac OS X most of the time and ArcGIS is not available for Mac. It doesn’t have to be the standard.

I’ve tried my hand at Cartographica and QGIS. I really like QGIS because there’re many plugins, it’s open source, there’s a diverse community supporting it, and best of all, it’s free. I’ve written about Cartographica once – I’m not a fan right now.

My project

  • The data: Bicycle crashes in the City of Chicago as reported to IDOT for 2007-2009
  • Goal: Publish an interactive map of this data using Google Fusion Tables and its instant mapping feature.
  • Visualizing it: Added streets (prepared beforehand to exclude highways), water features, and city boundary (get that here)
  • Process: Combine bike crash data; reproject to WGS84 for Google; remove extraneous information; add latitude/longitude coordinates; export as CSV; upload to Google Fusion Tables; map it!
  • View the final product

Trying out uDig

In reaching my goal I had a task that I couldn’t figure out how to complete with QGIS: I needed to combine three shapefiles with identical table schemes into one shapefile – this one shapefile would eventually be published as one map. The join feature in fTools wasn’t working so I looked for a new solution, uDig, or “User-friendly Desktop Internet GIS.”

The solution was very easy. Highlight all the records in the attribute table of one shapefile, click Edit>Copy, then select the destination table and click Edit>Paste. The new records were added within a couple seconds. I could then bring this data back into QGIS to finish the process (outlined above under Project). I did use fTools later in the process to add lat/long coordinates to my single shapefile.

After adding more data to better visualize the crashes in Chicago, I noticed that uDig renders maps to look smoother and slightly prettier than QGIS or ArcGIS. See the screenshot below.

A screenshot of the three bicycle crash datasets (2007, 2008, 2009) with the visualization data added.

The end product: three years of police reported bicycle crashes in the City of Chicago on an interactive map powered by Google Fusion Tables, another product in Google’s arsenal of GIS for the poor man. View the final product.

*I haven’t used ArcGIS version 10 yet, which I see and read has an improved user interface; it’s unclear to me and other users if the program’s been updated to take advantage of multi-core processors. ESRI has a roundabout way of describing their support.

High-speed rail in Illinois, February 2011 edition

View a map of the places described in this article.

A friend of mine traveled by Amtrak’s Lincoln Service from Chicago to St. Louis in January 2011. He reported, “It’s extremely smooth north of Alton and south of Lincoln. You can barely even hear or feel that you’re on a train.” Track replacement as part of President Obama’s economic stimulus and high-speed rail plan is complete between Alton and Lincoln, Illinois.

The next track replacement phase will take place between Lincoln and Dwight, scheduled to be completed in Fall 2011. A December 2010 press release from the Illinois Department of Transportation (IDOT) explains the next steps for the first state to begin construction on high-speed rail grants provided by American Reinvestment and Recovery Act (ARRA):

  1. Installation of new, enhanced grade crossing warning protection
  2. New cars and locomotives
  3. Station upgrades

Like all press releases, this one also seems to ooze idealistic endeavors by adding that the “public can expect to enjoy its first taste of 110 mile-per-hour train service when a 20-mile segment between Dwight and Pontiac is completed in 2012.” But this project has a high likelihood of being completed as described.

A better way for bike storage on trains

UPDATED: How BART (Bay Area Rapid Transit, San Francisco region) treats bikes on board. Simple signage and a bike graphic tell all passengers where bikes belong. Photo by Jim Dyer. More photos.

Look at the photo below and take in all the details about the bicycle’s position and orientation in relation to the vestibule, modesty panel, doors, seating, and aisle. Accommodating bicycles on many of the Chicago Transit Authority’s ‘L’ cars can be a hassle, not only for the bicycle-toting customer, but for the other passengers as well.

This photo shows what I see as the only appropriate location for a bicycle on the Red Line’s 2600-series car.

The passengers may be hit by wheels or handlebars, or have their personal space intruded upon or reduced.

The bicycle owner has the responsibility to ensure they don’t hit or disturb other passengers – to be successful with this on every trip is nearly impossible. Additionally, according to the platform position, the owner will have to move their bicycle to the other side of vestibule to allow access to the doors and aisle. Sometimes other passengers are already standing there, not paying attention, and it can be almost embarrassing to ask them to excuse you and your bicycle.

The 2600-series car in which I rode and took these photographs was built in the 1980s. I think it’s safe to say that the designers and engineers at CTA and Budd Manufacturing didn’t consider the spatial needs of bicycles in the plans. And retrofitting train cars is expensive. Bicycle riders in Chicago “get by” with the current rolling stock. (The train cars with the butterfly doors cannot accommodate wheelchairs or bicycles – there are 2 of these cars on many Blue Line runs.)

But there’s an opportunity to change things because the CTA will be asking Bombardier Transportation for some refinements on the 5000-series cars that the transit agency has been testing on all lines. Now’s our chance to request changes!

If you don’t know of the differences beforehand, you can’t recognize that this is a brand new car with a slightly different exterior design. The interior, however, differs wildly.

The most striking distance is the longitudinal or aisle-facing seats.

The new train car now provides two spaces for passengers in wheelchairs (look in the middle for the wide seat backs facing you). The seats flip up and there’s a seatbelt to hold the wheelchair in place. Photo by Kevin Zolkiewicz.

Based on the design we’ve all seen, I suggest the CTA and Bombardier make the following changes to better hold bicycles on board:

  1. With signage and markings (on the interior walls and floor), indicate that the space for wheelchairs is a shared space and that passengers with bicycles may also use it. The signage would mention that customers with disabilities always have priority as well as mention the times bicycles are allowed on-board. This change would send a stronger message to all other passengers that bicycle owners also have a priority to use this space and they may be asked to move so a bicycle can fit here.
  2. In an educational and marketing campaign, teach customers about bike-on-board rules, where to place bicycles on the ‘L’, and where and when customers can expect passengers with bicycles.
  3. On or near the train door exterior, use markings to indicate where passengers with bicycles should board. The current system has a sign on one entrance saying, “Limit 2 bicycles this car” (see photo below). The other entrance has no sign. The confusion lies here: Should two bicycles occupy the same space, at one end of the car and only enter through the door with the sign? Or should two bicycles occupy opposite ends of the car and enter through either door? If the former is preferred, the second door could have a sign that says one should enter with their bicycle through the other door.
  4. Install a method or mechanism that can hold a bicycle still. This could be with a hook, a seatbelt, or a “groove” in the floor. In Minneapolis, passengers with bicycles can hang them (see photo below).
  5. Install a light at each door in the car that would pulse to indicate which doors will open at the next platform (left or right). This can help passengers with bicycles know where other customers will be alighting and boarding.

I have some other ideas for the 5000-series cars but not related to bicycling.

More transportation analysis:

I should note that contrary to the belief of many Chicagoans (and perpetuated by the implications of at least one candidate), the Chicago Transit Authority is a quasi-governmental agency (or “municipal corporation”) created by the Illinois state legislature. A detailed description from Chicago-L.org:

The governing body of the CTA is the Chicago Transit Board consisting of seven members, of which four are appointed by the mayor of Chicago and three by the governor of Illinois. Each’s appointment must be approved by the other. Each board member serves a seven year term, staggered to minimize abrupt changes in policy. The board chooses a General Manager (changed to “Executive Director” in 1976 and now called “President” since March 1992) to oversee day-to-day operations. The first board took their oath of office September 1, 1945, with the first Executive Director, Walter J. McCarter, taking office in 1947.

The board, at least since Frank Kreusi, has always hired the president that Mayor Richard M. Daley chose, although it is not the mayor’s responsibility.

Emanuel releases plan for safe bicycling in Chicago. I reconsider.

UPDATE: I forgot to mention in the original post that Rahm gave a press conference on Sunday at Rapid Transit Cycleshop in Wicker Park (the bike shop doesn’t endorse any candidate for mayor). More photos from the event here and here.

Before Sunday, January 30th, 2011, when candidate for Chicago mayor Rahm Emanuel released details of his plans for bicycling in Chicago, I was a big fan of Miguel Del Valle (read my earlier posts).

I was excited by what he included and it made me think that someone’s been to New York City recently (or knows someone else who did), or Rahm watched Randy Neufeld talk about ten great ways to make bicycling great in Chicago.

So what does Rahm say? (Specifics in bold.)

  • Chicago lags behind many other cities in the rate of new bike lanes each year and providing bike parking in buildings. – Yep, check San Francisco, Portland, and New York City.
  • He will build 25 miles of new bike lanes each year and prioritize protected bike lanes. Great, Chicago will finally catch up on this sought-after bikeway over 12 years after one was installed in Davis, California. New York City installed several miles of this (“cycletrack”) in Manhattan in 2008 and continue today.

New York City’s first protected bike lane, or cycletrack, on 9th Avenue in Manhattan’s west side. Will Rahm’s administration install something like this in Chicago before 2015?

  • “…initiate a review of [the Bike 2015 Plan’s] goals and timelines to identify opportunities to expand the plan and accelerate the pace of implementation.” Right on. This needs to be done so we know our progress.
  • “…create a bike lane network that allows every Chicagoan – from kids on their first ride to senior citizens on their way to the grocery store – to feel safe on our streets.” Hey, that’s exactly what Randy said: Make bicycling for everyone, “from 8 to 80.”
  • Rahm will have the Bloomingdale Trail open and functional by the end of his term. The abandoned, elevated rail line promises to be an important part of the bikeway network, but also a neat recreational facility.

The Bloomingdale Trail is an elevated railroad viaduct (at 1800 North) running from Lawndale Avenue east to Ashland Avenue (possible to Elston Avenue). It is just under 3 miles of uninterrupted, car-free transportation for people walking and bicycling. Photo by Kasey D.

  • Make an ordinance that says buildings with over 200 workers must install indoor bike parking. More than their desire for workplace showers, people who bicycle to work (or are considering it) want a secure place to store their bike for 8+ hours.
  • Double the number of on-street bike parking, including in neighborhoods. This is another point Randy made – there must be a place to park one’s bike at home!

There are many opportunities in Chicago to install bike parking for neighbors. Not everyone can fit their bike inside or bring it up to the fifth floor. Bike parking could occupy a section of a wide parkway, or be in the street, providing space for 16 bikes where only 1 car can fit. Photo by Jonathan Maus.

So far, no other candidate for mayor has released such a detailed and specific plan to include bicycles as a part of Chicago’s transportation system.
