SIMULATION ANALYSIS OF A COMPUTER-CONTROLLED FREEWAY MERGING SYSTEM
In 1970, Raytheon Company conducted preliminary field tests on two types of moving merge control system at a freeway entrance ramp. The tests demonstrated the operational feasibility of both systems, and established a driver preference for the "GREEN BAND SYSTEM " concept, which displayed bands of light moving along the ramp corresponding to acceptable gaps available in the freeway traffic stream for merging vehicles. Operational experience with the Green Band System in Tampa identified occasional problems with band stability which have the potential for reducing driver confidence in the operation of the system. To establish a tool for studying the problem, a simulation model for the on-line control system was developed. The paper presents the structure of the finalized FORTRAN model for the on-line control program and outlines techniques for generating animated movies of system operation from the simulation outputs. Improvements to existing control algorithms made possible through identification and testing with these films are discussed.
