DMS Travel Time Pilot Project Evaluation: Executive Summary and Research Acknowledgements

"In January 2008, ADOT initiated a pilot project to display freeway travel times on selected dynamic message signs (DMS) in the Phoenix metropolitan area. The Travel Time Pilot Project included travel time messages being displayed on 12 DMS ... An evaluation ... was conducted to identify if there were any impacts to freeway speed, mobility, or crash rates ... also ... to obtain user feedback ... The goals of the DMS Travel Time Pilot Program evaluation were to: evaluate impacts to freeway operations and freeway mobility as a result of posting travel time messages on DMS during peak hour travel; evaluate and document customer response to freeway travel time messages for use in development enhancements or recommended modifications to the DMS Travel Time Pilot Program; and, compare the accuracy of travel time messages being displayed with actual travel times" --Executive summary
