摘要

在本研究中，在四个试验十字路口将排他左转相位改为允许左转相位。试验安装前后分别进行了交叉口延误和事故研究。此外，还分发了一份调查表，以确定公众对该信号的意见。在这项研究的结果中，发现:在肯塔基州列克星敦的几个地方，与不允许相位相比，允许相位导致左转延迟减少50%(总交叉延迟减少24%);宽松的分阶段导致了事故的增加;问卷调查结果显示，该地区90%的司机赞成允许左转;必须签署以告知驾车人士“允许分阶段”的含义;安装前应进行预先宣传。

AN EVALUATION OF PERMISSIVE LEFT-TURN PHASING

In this study exclusive left-turn phasing was replaced with permissive left-turn phasing at four trial intersections. Intersection delay and accident studies were done before and after the trial installations. Also, a questionnaire was distributed to determine public opinion concerning the signal. Among the results of this study it was found that: permissive phasing at several locations in Lexington, Kentucky resulted in a 50 percent reduction in left-turn delay compared with exclusive phasing (total intersection delay was reduced 24 percent); permissive phasing resulted in an increase in accidents; questionnaire responses showed 90 percent of drivers in the area to be in favor of permissive left-turn phasing; signing to advise motorists of the meaning of permissive phasing is required; and advance publicity should precede installations.
