DEVELOPMENT OF AN INTEGRATED MODEL FOR EVALUATING TRAFFIC MANAGEMENT PLAN

It was noted that a well developed traffic management plan (TMP) is very important for any construction conducted in an urban area in order to maintain existing traffic during the construction period. In this study, programs MINUTP and TRANSYT-7F were integrated as a model for evaluating the TMP. The MINUTP handles the traffic assignment of the analyzed network, and the TRANSYT- 7T simulates the traffic delay based on the assigned traffic volumes resulted from MINUTP. The simulated delay was, then, fed back into the MINUTP to improve its rough prediction of intersection delay. The iterative process among MINUTP, TRANSYT-7F, and two interface programs was continued until the convergent stage was reached. The screen-line volume, total travel time, total travel distance, and average travel speed calculated from the last iterative run can be used optionally as the criteria for evaluating the performance of proposed TMPs. Furthermore, this integrated model has the functions of optimizing the traffic signal system and graphically displaying the level of service of the analyzed network. All the features are very useful for users to select and analyze the traffic management alternatives. It was found that the integrated model of MINUTP and TRANSYT-7T provides a simplified but reliable evaluation strategy for TMPs in urban areas.
