BRT站台行人交通模拟

摘要

为准确实时评价BRT (bus rapid transit)站台服务水平、探寻行人运动集散规律，提出BRT行人交通模型，包括站台设施模型以及融合宏观网络拓扑路径导航、中观事件决策、微观单步运动三层算法的个体决策与运动模型，并加入闸机与上下车排队算法构建出行候乘行为。通过BRT乘客出行模拟实例对模型进行可靠性与实用性验证，验证结果表明，该模型具备模拟不同模式站台、正常行走和紧急疏散等多模式情景的能力。%To explore passenger movement law and evaluate BRT stations’facility and service quality in real-time,the model of pedestrian traffic in BRT station was proposed.The model including the mechanism of BRT station facility modeling and the model of individual decision and movement in which macro-level topology,middle-level incident decision and micro-level move-ment were combined,and it was concretized with waiting behavior including turnstile system and queue process.BRT passenger data were connected and simulated to verify the reliability and practicability of the model.The results indicate that the model has the ability to simulate pedestrian traffic situation on different station types and different evacuation conditions.
