构建生态人文交通 促进经济跨越发展:第十九届海峡两岸都市交通学术研讨会论文集 2010年台北市号志适应性控制策略实作 林宜达，翁忠川，林俊甫，钟仁杰 摘 要：台北市近年为期有效提升路口号志控制系统之交通变化适应能力，积极进行动态号志控制策略计 划，并于 2009 年试办动态号志之适应性号志策略及支道触动号志策略等，成效良好。2010 年乃扩大适应 性号志策略之试办范围，针对台北市二处瓶颈路口进行适应性控制策略研拟、软硬件建置整合、微观模拟 绩效分析及试办绩效分析等。 为因应试办路口道路线型弯曲视距短之特殊几何特性，及高快速公路下匝道平面路口之特殊管制与交 通特性，个别提出修正之适应性控制策略逻辑，并利用 VISSIM 微观仿真软件之 VAP 动态策略建构模块进 行控制策略建构、路网平台模拟与绩效评估；微观仿真平台结果显示二处试办路口之动态控制策略执行皆 具一定之成效。 关键词：动态号志；适应性号志；VISSIM 微观车流模拟；VAP 动态控制 Strategy Practice of Adaptive Signal Control System in 2010, Taipei Abstract: In order to enhance an ability of signal control system to adapt to traffic flow changes in the intersection in Taipei city, we developed dynamic traffic control strategy in recent years. In 2009, this study developed adaptive traffic signal control strategy and semi-actuated control strategy, which was found that it can reduce stop delay for per vehicle after field tests. In 2010, this study continue developing adaptive signal control strategy, integrates software and hardware developing of adaptive signal control model, and evaluates by both VISSIM micro-simulation and field tests for two traffic bottleneck intersections. Due to sight restrictions on the horizontal curves of the intersection and traffic characteristics of off-ramp from highways, we proposed revised adaptive traffic signal control logic, simulated traffic network ,and evaluated the results by using VAP dynamic strategy module of VISSIM micro-simulation software. The results show that dynamic traffic control model is more effective.
