政府已制订各种交通管理策略，以纾缓高速公路的挤塞情况。公平问题一直被认为是一些交通控制策略实施的主要挑战之一，特别是匝道计量。本文对固定时间匝道计量（FTRM）交通控制策略的效率和公平性进行了比较评价。本文不关注单一的公平措施和/或指标，而是讨论了公平概念的不同方法，并检查了各种公平措施。并结合模拟廊道，对交通管制策略的公平性和效率性能进行了比较和评价。以土耳其伊斯坦布尔O-1高速公路博斯普鲁斯大桥作为仿真模型的试验台，通过微观交通流仿真软件VISSIM AG采用控制策略。仿真结果表明，网络的公平性和效率特性随着所考虑的度量和指标的不同而变化。结果还表明，公平和效率之间的权衡可以在某些措施中观察到，而关于其他措施的权衡没有得到验证。
Various traffic management strategies have been developed to alleviate the congestion on freeways. The equity issue has been considered as one of the major challenges for the implementation of some traffic control strategies, especially ramp metering. This paper presents a comparative evaluation of the efficiency and equity performance of a traffic control strategies namely Fixed Time Ramp Metering (FTRM). Instead of focusing on a single equity measure and/or indicator, different approaches to the equity concept are discussed and various equity measures are examined. The equity and efficiency performance of traffic control strategies are compared and evaluated by incorporating them into the simulated corridor. The Bosporus Bridge of Istanbul O-1 Freeway, Turkey is used as a test-bed for the simulation model and the control strategy is employed through microscopic traffic flow simulation software, VISSIM AG. The findings from the simulations show that the equity and efficiency properties of the network vary with the measures and indicators taken into account. The results also suggest that the trade-off between equity and efficiency can be observed for some measures, whereas regarding to other measures the trade-off is not validated.
