• Abstract:
  The Driver Information Radio using Experimental Communication Technologies (DIRECT) Operational Field Test (OFT) aims to increase the number of drivers who are aware of traffic incidents on their route by offering affordable route-specific automatic alerting. Both broadcast and roadside localcast delivery methods were tested on a 15-mile segment of 1-75 in the Detroit area. Recruited drivers who used the segment on their commute route drove vehicles equipped with one of the delivery methods. Traffic information was provided by a professional announcer located at the Michigan Intelligent Transportation Systems Center (MITSC). The broadcast method used the Radio Data System (RDS) digital subcarrier of WDTR’s FM signal to control the RDS entertainment radio; the analog traffic information was on another subcarrier. Four roadside localcast transmitter sites in the segment implemented a localized Low Power HAR and an Automatic HAR.
