Active Traffic Management Study

completed

This project determined both the comprehension of the active traffic management (ATM) signs as well as the legibility distance of these signs, and determined how motorists respond to these signs in a simulated driving environment. This final report describes a series of experiments that developed alternative signs focusing on dynamic lane assignment and variable speed limits and used the deployments in Minnesota and Washington as one of the inputs to sign development. Laboratory and field studies determined both the comprehension of the ATM signs as well as their respective legibility distances. Two driving simulator studies helped determine how motorists respond to these signs in a simulated driving environment.
