Abstract

The increasing activity in controlling access to freeways for the purpose of improving traffic flow has focused on the need to develop control policies for treating the entire corridor network system. This system comprises freeway, servicing ramps, frontage road, and parallel and feeder arterials. It has been observed that ramp metering, while improving conditions on the freeway, can precipitate congestion on the grade roadways. The SCOT model was developed as an evaluative and design tool to predict the performance of alternative control policies and freeway configurations prior to field implementation. A dynamic representation of traffic flow is produced by the model. This paper described the capabilities and prominent features of the model and some of its representative results.
