摘要: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。

Abstract:This is the most extensive empirical evaluation of the effectiveness of California's HOV system based on data collected from traffic sensors. The evaluation leads to four major conclusions. 1) Since it operates as a single lane freeway, an HOV lane suffers a 20% capacity loss compared with multi-lane freeways. 2) HOV lanes are either under-utilized or suffer degraded operations. 3) HOV lanes do not measurably increase car-pooling. 4) HOV lanes do not reduce overall congestion in a reasonably well-managed system.
