摘要：	This paper describes a procedure for testing the accuracy of travel times displayed on dynamic message signs (DMSs) using global positioning system (GPS) technology. The procedure relies on the capability of GPS receivers to time tag position observations automatically. It also relies on the capability of a traffic management center to generate electronic logs documenting DMS message updates throughout the day. The paper documents the use of the procedure to evaluate the accuracy of travel time information displayed on DMSs in San Antonio, Texas. The paper describes the data collection approach, the synchronization procedure used to match the GPS data with DMS travel time readings, and analysis of the results obtained.
