I assisted Nabil Nazha in gathering data and developing a methodology for the geographic analysis of bicycle crashes at intersections needed to complete his master’s thesis from the University of Illinois at Chicago’s College of Urban Planning and Public Affairs (CUPPA). I graduated from CUPPA in 2010. We submitted his paper to the Transport Chicago conference and it was accepted; see Session 1 – A Safety Dance. He was out of the country at the time of the conference so I gave this presentation alone.

Bicycle crashes at intersections are the topic of the paper, Safe Cycling in Chicago. Continue reading Bicycle crashes: A presentation at the Transport Chicago conference

This map shows that 58.8% of Chicago streets, excluding highways, are eligible for speed camera enforcement. Open the map.

The Expired Meter has been tracking the speed camera issue very well. (Here’s our coverage.) Along with reporting that an ordinance would be introduced to alderman at tomorrow’s monthly City Council meeting, it reported Monday on an interview with Alderman Waguespack who had been briefed on the city’s speed camera goals:

Originally, city officials claimed existing red light camera locations would be utilized to do double duty and be retrofitted to also do speed enforcement.

But, according to Waguespack’s understanding of the briefing presented by officials from the Mayor’s office, Chicago Police Department and Chicago Department of Transportation, the city’s long range goal is to install speed cameras at 1,800 intersections near school and parks under the auspices of slowing down drivers through $50 to $100 fines for speeding near these intersections. The state law calls for cameras to be used within a 1/8 of a mile safety zone surrounding the schools and parks. [They can be used in those areas, and in no other areas.] Continue reading Speed cameras: There’s more than meets the eye (updated)
