EVALUATION OF UTAH TRANSIT AUTHORITY'S CONNECTION PROTECTION SYSTEM

The Utah Transit Authority (UTA) implemented a Connection Protection (CP) system to improve the reliability of transfers from the higher frequency light rail TRAX trains to the lower frequency bus services. The CP system examines the status of TRAX trains and issues a "hold at {station name} until {time}" message to buses waiting at the connecting rail stations via the bus' onboard Mobile Data Terminal (MDT), if the lateness of train is within a pre-determined threshold (e.g., 3 minutes). The system was completed and tested in January 2002 prior to the Winter Olympic Games in Salt Lake City. The successful implementation and operation of the CP system has received attention from the Federal Transit Administration (FTA) and the U.S. Department of Transportation (USDOT) Intelligent Transportation System (ITS) Joint Program Office (JPO) to warrant a national evaluation study. The objectives of the evaluation are to assess and document the performance of the CP system and share the experiences and lessons learned with other agencies that may be considering a similar system.
