路段通行能力的理论探讨

回顾了现行路段通行能力的计算方法，剖析了其在理论体系和实际应用方面存在的问题，在全面分析行车间距特性的基础上，提出了路段通行能力分析的理论体系和新定义，从而实现了交通流理论和通行能力分析折协调统一。这些内容对于完善交通工程学基础，改进通行能力分析方法和指导通行能力手册的编制都具有重要的理论和实用价值。

Theoretical Study about Road Section Capacity

After reviewing the present computing methods for road section capacity, the existing problems of the present computing methods in their theory and actual application are analyzed, and a new theoretical system and its concept for the analysis of road section capacity are put forward on the basis of comprehensive analysis of the gap characteristics so as to achieve a good coordination between traffic flow theory and capacity analysis.The above research contents are valuable to the perfection of traffic engineerig, the bettering of the methods of capacity analysis and the guidence for compiling Highway Capacity Manual.
