An Optimization Model for Freeway Stationary Emergency Service Systems

This study is concerned with the analysis of a stationary emergency service system, and includes the application of this analytic procedure to the Los Angeles Freeway Surveillance and Control Project. The stationary emergency service system is interpreted as an ordinary queuing system and is approximated by an M/G/∞ model. In conjunction with queuing theory, dynamic programming is used to determine the best locations for service facilities, the optimal number of service vehicles at each service location, and the service area covered by an individual service location.
