Evaluation of the Anaheim Advanced Traffic Control System Field Operational Test: Introduction and Task A - Evaluation of SCOOT Performance

Summary Information

Anaheim, California is an urban area with a population of 300,000. Within a 3 square mile area of the city there are 4 major event centers having a combined maximum attendance of 200,000 people. This study evaluated the implementation of the Split Cycle Offset Optimization Techniques (SCOOT) adaptive signal control system on a traffic signal network surrounding two of these event centers. The study used a before and after approach, with 10 observations before the implementation and 10 after. Travel times were determined using the floating-car technique on 5 routes before and after implementation. The study evaluated the ability of SCOOT to function using existing mid-block loop detectors rather than standard upstream intersection detection.

The change in travel times for the routes in the study ranged from a decrease of 10 percent to an increase of 15 percent. More circuitous routes involving more of the SCOOT system saw travel time changes ranging from a 2 percent reduction to a 6 percent increase. The relative performance against the baseline system was better when there were no events at the centers being studied.
