为了解加利福尼亚州HOV系统的运行效果,基于交通量检测器收集的数据,对HOV系统进行全面分析、评价。最终得到4个主要结论:1)与多条普通车道构成的高速公路相比,包含1条HOV车道的高速公路损失了20%的通行能力;2)HOV车道通常处于两种运行状态,一种是HOV车道未被充分利用,另一种是HOV车道处于超负荷、降级运行状态;3)HOV车道未显著提高小汽车合乘比例;4)在一个相当出色的交通管理系统中,HOV车道并未从整体上缓解道路交通拥堵状况。
To understand the operational effectiveness of the HOV system in California, a comprehensive analysis and evaluation of the HOV system was conducted based on the data collected by the traffic detector. There are four main conclusions: 1) The highway with one HOV lane loses 20% of the capacity compared to the freeway with multiple lanes; 2) HOV lanes are usually in two operating states, one HOV lanes are underutilized, and HOV lanes are overloaded and downgraded; 3) HOV lanes do not significantly increase car co-ordination; 4) In a fairly good traffic management system, HOV lanes and Overall traffic congestion has not been alleviated.
