A unique instrumentation system termed the TRADAC System has been developed to be used in conjunction with the test-car method for traffic data collection. This system measures travel time, stopped time, number of stops, and number of brake applications. Traffic performance data can be collected in a more cost/effective way with the TRADAC System than with other existing data collection systems, effecting tremendous savings in time due chiefly to the expeditious reduction of the collected data. The system was extensively tested and demonstrated to produce accurate and reliable measurements of the traffic performance variables.
