深圳541個(gè)路口夜間信號燈完成優(yōu)化！這些變化你發(fā)現了嗎？

2019-12-31 15:22來(lái)源：深圳新聞網(wǎng)

坪山區

蘭竹/翠景路口位于坪山區龍田街道，蘭竹路貫穿坪山大工業(yè)區，是連接深圳坪山中心區和惠州惠陽(yáng)的東西向主干道，路口周邊均為工業(yè)園，夜間20時(shí)至21時(shí)正值路口附近工廠(chǎng)下班時(shí)間，各方向過(guò)街行人流量大。

蜀黍調研發(fā)現，該路口夜間工廠(chǎng)下班時(shí)間段人車(chē)沖突嚴重，存在安全隱患，且22時(shí)后東西方向空放嚴重。

針對上述情況，蜀黍采用了一套組合拳：一是時(shí)間、空間上將行人與機動(dòng)車(chē)進(jìn)行分離，20時(shí)至21時(shí)期間采用南北單放，以消除人車(chē)交織、車(chē)車(chē)交織，保障行人過(guò)街安全。二是精簡(jiǎn)相位，把22時(shí)至次日6時(shí)期間的四相位方案更改為三相位方案，以降低夜間路口周期，減少空放。

優(yōu)化改善后，路口夜間周期由102秒下降至87秒，路口空放明顯減少；人、車(chē)交叉沖突點(diǎn)數由2個(gè)減少至0個(gè)，基本實(shí)現人車(chē)獨立通行路權，行人過(guò)街安全得以保障。
