1 城市道路信号交叉口是城市道路的重要节点，它把城市道路相互连接起来构成道路网，其通行能力直接影响城市道路的通达，交叉口的交通流密度过大，将会造成路口的拥挤与堵塞，影响城市道路的正常运行，而提高信号交叉口通行能力、减少交叉口停车延误是城市道路交通追求的目标，鉴于此，以信号交叉口为研究对象，通过典型交叉口的调查，探究其通行能力，并分析信号交叉口的运行状况。 对石家庄市体育南大街与槐安路交叉口的通行能力及延误进行交通调查，计算交叉口的通行能力，分析交叉口的运行状况，分析其存在的问题，在此基础上提出提高了信号交叉口通行能力的建议。 关键词 城市道路；信号交叉口；通行能力；混合交通流 毕 业 论 文 外 文 摘 要
2 Title Sports and Huai an Road South Street intersection Capacity Analysis Abstract Signalized intersection is the important component of the urban road. It connects urban road up a road network, and its capacity directly affect the running efficiency of the urban road. Urban road will not work normally if the traffic congestion or jam when the traffic flow desity of the intersection is too large. To improve the traffic capacity and reduce parking and delaying in the intersection are the goals of urban road traffic. For reason above, the signal intersection is studied as a research object, and the traffic capacity of intersection is explored. The running status of the signal intersection is analyzed in this paper. South Street, Shijiazhuang City Sports Huai An Road intersection with the traffic capacity and delay traffic surveys, calculated Intersection ability to analyze the operation of the intersection, and to analyze its problems, on this basis, proposed to increase the signal crossing capacity mouth recommendations.
