Abstract

Abstract: The mathematical model about the road capacity was built based on the driving behavior mode of the conservative pattern，moderate pattern and venturesome pattern. According to the acquired mathematical formulas，the influence of automobile dynamics performance and handling stability on road capacity was analyzed. That is reliable mechanism design and extensive application of advanced technologies，just like ABS and automatic transmission，which are beneficial to minish distance headway and improve road capacity. Saturated traffic capacity of departing from intersection will also have an increment with the improvement of automobiles’acceleration. The realization of Cruise Control System and Formation of Navigation in future may cause an essential augment of traffic capacity. The increment of road capacity will become an inevitable trend.

Key words: road capacity, mathematical model, automobile performance, automobile technology

摘要： 基于保守型、稳健型及冒险型3种驾驶行为模式，建立了道路通行能力数学模型;以所得数学模型为依据，分析了汽车动力学性能以及操纵稳定性对道路通行能力的影响，结果表明:可靠的机构设计、ABS、自动变速等先进技术广泛应用有利于减小行车间隙，提高通行能力;交叉口的驶离流率也会随着汽车加速性能提高而有所增加;未来自动驾驶及编队行驶技术的实现更可能引起通行能力本质性的提升。
