Estimating the Crash Reduction and Vehicle Dynamics Effects of Flashing LED Stop Signs

Summary:

In a field study, portable video equipment was used to record vehicle approaches at an intersection before and after installation of flashing LED stopsigns. After installing the flashing stop signs, there was no change in the relative proportion of clear stops to clear non-stops when minor approach drivers did not face opposing traffic, but the relative proportion of clear stops increased for drivers who did encounter opposing traffic.
