In the Fall of 2007, nine problematic intersections throughout the city of Chicago were painted with a green preformed thermoplastic marking to test the effectiveness of the color in alleviating conflict between cyclists and motorists turning right at intersections. In most cases, color was applied between the thru lane and the weaving area, where cyclists most often experience obstruction and discomfort. Video of each intersection has been recorded, though it has yet to be heavily analyzed. Maintenance issues with the material have occurred, such as flaking of the markings following the winter months, though this may be attributed to poor installation.
