The invention provides an urban traffic system capacity analysis and optimization method. The method comprises the following steps: S1, inputting basic data; S2, calculating a maneuvering travel totalamount and a mode structure in a peak period; S3, decomposing and calculating the maneuvering travel volume borne by the road traffic network and the rail traffic network, and calculating the statictraffic demand; S4, calculating a saturation state judgment index under a basic condition; S5, judging whether the average travel time and 95% travel time reach the standard or not; S6, judging whether the average travel time ratio of the public traffic to the individual traffic reaches the standard or not; S7, and outputting result data. The method can be applied to urban intelligent traffic system construction, and a quantitative and scientific auxiliary decision-making technology is provided for orderly and reasonable development of urban construction land and traffic control.

    本发明提供一种城市交通系统容量分析优化方法,包括以下步骤:S1、输入基础数据;S2、计算高峰时期机动化出行总量和方式结构;S3、分解计算道路交通网络、轨道交通网络承载的机动化出行量,计算静态交通需求量;S4、计算基本情形下的饱和状态判定指标;S5、判定平均出行时间和95%位出行时间是否达到标准;S6、判定公共交通与个体交通的平均出行时间比值是否达到标准;S7、输出结果数据。本发明可应用于城市智慧交通系统建设,为城市建设用地有序合理开发和交通治理提供定量科学的辅助决策技术。
