山地城市路侧公交优先道通行能力研究

Research on Traffic Capacity of Roadside Public Transport Priority Roads in Mountainous Cities

设置公交优先道是缓解山地城市交通压力的有效措施,构建体现山地城市路侧公交优先道通行能力的计算模型有助于掌握并提升公交优先道的通行效率。分析山地城市路侧公交优先道路段特征,从而根据通行能力主要影响因素分析山地城市特征,提出路侧公交优先道通行能力计算模型思路并基于已有模型进行优化,构建山地城市路侧公交优先道通行能力计算模型。结合实际数据进行验证,得出优化模型计算结果与实际通行能力误差在可接受范围内,即该优化模型能较准确地计算出山地城市路侧公交优先道实际通行能力。

Setting the bus priority lane is the key method to alleviate the traffic pressure in mountainous cities.The project explore a calculation model suitable for the traffic capacity of roadside bus priority lanes in mountainous cities that can help improve the transportation efficiency of bus priority lanes.The main influencing factors of the traffic capacity are selected,and the calculation model of the traffic capacity of the roadside bus priority lane sections characterized by the characteristics of the mountainous cities are proposed,combined with the analysis of the characteristics of it in mountainous cities.The possible capacity calculation model of basic road sections that can reflect the characteristics of mountainous cities,and the capacity calculation model of bus priority lanes in mountainous cities is constructed to analyze the influence coefficient of influencing factors of road opening,based on the summary and analysis of the existing capacity calculation models.The model optimization results are verified,combined with the actual data of mountainous cities,and it is concluded that the error between the calculation results of the optimization model and the actual capacity is within an acceptable range,that is the optimization model can more accurately calculate the actual capacity of roadside bus priority lanes in mountainous cities.
