A GENERALIZED STREET NETWORK SIMULATION MODEL

This paper describes a microscopic simulation model that reproduces traffic flow on a signalized street network under laboratory conditions. The input format and structure of the program facilitate application to any moderate-sized network. The program is economical to use, achieving a 6.5-to-1 real-time to simulation-time ratio for an 85-link network. The model has undergone a testing and validation procedure in which simulated vehicular travel times have been compared with actual travel times recorded on the test network to evaluate overall model accuracy. An analysis of individual model segments has been conducted to test their sensitivity to changes in key parameters. Results of these tests indicate that the model accurately and realistically simulates traffic flow through the street network.
