Abstract:

Active traffic management (ATM) incorporates a collection of strategies allowing the dynamic management of recurrent and nonrecurrent congestion based on prevailing traffic conditions. These strategies help to increase peak capacity, smooth traffic flows, and enhance safety on busy major highways. This final report describes a series of experiments that developed and tested alternative signs focusing on lane control signs (LCS) and variable speed limit (VSL) signs and used the deployments in Minnesota and Washington as 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 responded to these signs in a simulated driving environment. Research results are discussed for the various studies, including legibility distances, driver behavior, speed selection, and visual clutter with respect to the used of the LCS and VSL signs.
