Identifying the maximum wave velocity , the actual capacity can be calculated . the maximum wave velocity can be determined upon the data in low density 采用本文的公式计算实际通行能力时，只需要根据实测数据确定最大波速，而低密度的数据足以确定最大波速。
Abstract : it is main objective to improve the capac ity of intersections , because the capacity of intersection affects the efficiency of the highway network 文摘:交叉口通行能力的大小直接影响到整个路网效率，提高交叉口的通行能力是目前道路网的重要目标之一。
This paper , with a view to improving city intersection traffic and safety , serves as an attempt to optimize the existing city intersection design 为了提高城市道路平面交叉口通行能力和确保安全的前提下，对现有交叉口优化设计上进行了有益的尝试，取得了良好的效果。
Non - touching 1c is used in the system , the traffic efficiency is improved and cost is lowered . the communication system is composed by fiber , exchanger and way - side telephone 并采用非接触式ic卡，大大提高了车道的通行能力，提高了日常工作效率，降低了营运成本。
This paper discusses the applications of this simulation system in three aspects , including road alignment , capacity of expressway system and simulation of urban artery 并从道路线形预审、高速公路系统通行能力分析、快速路系统仿真三个方面对系统仿真的应用进行了探讨。
Traffic bottleneck is the key point of traffic system . enhancement of the capacity in bottleneck area will improve the integrate operation performance of traffic network effectively 交通瓶颈是交通系统的薄弱环节,瓶颈通行能力的提高能有效改善交通系统的整体运行状况。
Under the condition that transportation condition , road condition and measure standard are given , the capacity of highway means the maximum traffic capability per unit time 公路通行能力是指在特定的交通条件、道路条件及人为度量标准条件下，单位时间内能通过的最大交通量。
Note that the only required network attribute for all - or - nothing assignment is a time field . all the other assignment methods require both time and capacity fields in the network file 注意，全有全无分配法所需的唯一属性为时间字段。其他所有的分配方法都同时需要时间和通行能力两个字段。
Since 80 ' s , many countries have built modern road networks . with the development of economy , the traffic capacity cannot catch up with the traffic raising 80年代以来，世界各国虽然基本建成了现代化道路网，但随着经济的发展，路网通行能力已经满足不了交通量增长的需要，交通拥堵现象日趋严重。
There are some differences in traffic capacity and function of each road line in the urban traffic network , for that reason the urban traffic network is separated into main trunks and branch trunks 本文的主要研究内容如下: 1 .针对区域交通路网中各线路的通行能力和功能的不同,将路网分为主干线和支线。
