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.
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.
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.
