基于快速公交（BRT）交叉口资源整合的信号优先算法研究

自2004年北京开通了我国首条城市快速公交（BRT）运营线路以来，至2012年底，全国城市快速公交（BRT）运营线路长度达1383公里，运营车辆达3975辆。而由于我国对快速公交（BRT）系统仍缺乏全面系统地了解，导致实际运营中，尤其是交叉口信号优先方面不能实现快速公交（BRT）服务效能最大化，因此有必要对其进行深入的研究。本文研究了基于快速公交（BRT）交叉口资源整合的信号优先算法，提出了建立模型的思想并构建了模型，同时，对建立的模型进行了验证。本研究对提高城市快速公交（BRT）运行效率和服务效能，方便乘客出行，减少环境污染等具有重要意义，从而可引导快速公交（BRT）系统为乘客提供更安全、更便捷地换乘服务。

Based on the study of Bus Rapid Transit signal priority algorithm of intersection resource integration China Academy of Transportation Siences

Since 2004, Beijing opened China＇s first urban Bus Rapid Transit line in operation, to the end of 2012, the National Bus Rapid Transit operated 1383 kilometers in length, operating vehicles up to 3975 vehicles. And because of our country Bus Rapid Transit system is still a lack of a comprehensive and systematic understanding, resulting in actual operation, especially cannot achieve rapid transit signal priority in intersection, and cannot to maximize service performance, so it is necessary to conduct in-depth research. In this paper, based on the study of Bus Rapid Transit signal priority algorithm of intersection resource integration, proposed the idea of establishing a model and build a model, while the establishment of the model is validated. In this study, improve the urban Bus Rapid Transit operating efficiency and service performance, facilitate passenger travel, reduce environmental pollution is of great significance which can guide the Bus Rapid Transit systems to provide passengers with a safer, more convenient transfer service
