| Summary: | 碩士 === 中央警察大學 === 交通管理研究所 === 87 === Bus preemption system offers the potential for great improvements not only in the person-carrying capacity and travel time incentive to users, but also in reducing energy consumption and pollution. Though "exclusive bus lane", it can increase 10% to 20% bus traveling speed. However, the "intersection signal" is always the major resource of its travel delay. Furthermore, on-going researchers still remain their study on the subject of fixed-time signal system about the intersection bus preemption model without considering the arterial bus priority strategies for progression control.
This paper focuses on developing a progression signal control model for arterial bus preemption. Based on the applying of the conventional arterial progression signal functions and facilities, the proposed model has been constructed for the exclusive bus lane with near-side stops under fixed-time signal control environment. Both the global optimum bus progression model (GOBPM) and the tuning bus progression model (TBPM) have been developed to satisfy different bus demand during peak and off-peak periods. In order to evaluate the system, we can use the softwares "PASSER IV-96" and "TRANSYT 7F" to provide the measure-of-effectiveness. Finally, the traffic simulation program is employed in testing the system performance under various traffic scenarios. The testing results show that both GOBPM and TBPM can respectively enhance 4.7% and 8.9% green band. In addition, they can also reduce 0.8% delay within the testing system. Thus, it is expected that the proposed arterial control system can outperform the existing intersection preemption model and enhance overall system control performance.
