针对左转车流影响交叉口通行能力的现象，选取左转视距受限的主干路-次干路“T”型交叉口为研究对象，提出“主路信控左转”、“主路远引左转”两种组织方案，并通过Vissim仿真软件对两种方案中交叉口延误、左转延误、左转运行时间等参数的对比分析，得出“主路远引左转”在T型交叉口的可行性。
針對左轉車流影響交扠口通行能力的現象，選取左轉視距受限的主榦路-次榦路“T”型交扠口為研究對象，提齣“主路信控左轉”、“主路遠引左轉”兩種組織方案，併通過Vissim倣真軟件對兩種方案中交扠口延誤、左轉延誤、左轉運行時間等參數的對比分析，得齣“主路遠引左轉”在T型交扠口的可行性。
침대좌전차류영향교차구통행능력적현상，선취좌전시거수한적주간로-차간로“T”형교차구위연구대상，제출“주로신공좌전”、“주로원인좌전”량충조직방안，병통과Vissim방진연건대량충방안중교차구연오、좌전연오、좌전운행시간등삼수적대비분석，득출“주로원인좌전”재T형교차구적가행성。
Considering the influence of left turn traffic at an intersection, the T-intersection is selected as the research obje-ct including a trunk road and a secondary road, and “the main road signal control left”and“the main road indirect left U-tur-n”two organization methods are put forward. The main road indirect left U-turn is feasible , through comparative analysis of intersection delay、turn-left delay and running time in the two programs based on Vissim simulation.
