为改善城市道路交叉口处的过街组织方式,保障过街安全,提出一体化行人流的概念。采用实地调查及数据统计与分析的方法,以呼和浩特市鄂尔多斯大街与昭君路平面4相位交叉口为例研究一体化行人流。通过实地调查,将一体化行人的过街行为进行方式分类,在分析交叉口现状的基础上探讨该交叉口一体化行人二次过街的必要性与可行性,最后提出改善方案。结果表明,安全岛的设置、专用信号灯的配置及适当的信号相位的设计,能在一定程度上保障一体化行人在交叉口处过街的安全和便利,减少机动车流与一体化行人流的直接接触,避免交通事故的发生。
In order to improve the way of crossing the street at the intersection of urban roads and ensure the safety of crossing streets, the concept of integrated pedestrian flow is put forward. Using the method of field investigation and data statistics and analysis, this paper studies the integrated pedestrian flow with the example of 4-phase intersection of Erdos Avenue and Zhaojun Road in Hohhot. Based on the field survey, the pedestrian crossing behaviors of the integrated pedestrian are categorized by way of classification. Based on the analysis of the current status of the pedestrian crossing, the necessity and feasibility of crossing the pedestrian crossing at the intersection are discussed. Finally, the improvement plan is proposed. The results show that the design of the safety island, the configuration of the special signal lights and the proper signal phase can ensure the safety and convenience of the integrated pedestrians crossing the intersection to a certain extent, reduce the direct contact between the motor vehicle flow and the integrated pedestrian flow, Avoid traffic accidents.
