“Left Turn”作为方向指示的一部分,与许多其他交通指示词汇紧密相关。例如,“intersection”表示交叉口,是左转操作经常发生的地点;“traffic lights”即交通信号灯,是控制左转时机的重要设施;“one-way street”指单行道,对左转操作有着特殊的限制和要求;“turn signal”则是转向灯,是左转前必须...
Left turn phases can be skipped if no traffic is there to use them. This is harder to predict with lagging turns. With leading turns, the signal can make the decision at the beginning of the time for that street. Left turn phases on the same street can be split, with one green arrow...
Because of the limited availability of right-of-way, many transportation agencies have started using unconventional traffic control systems for intersections to improve signal efficiency and reduce overall delays. Common unconventional left-turn control types such as the right-turn followed by a U-turn...

The intersection capacity is generally improved by setting left-turn waiting areas if there are more left-turn traffic flows and the intersection area is large.But setting left-turn waiting areas will also cause vehicles' secondary parking,which will result in increasing fuel consumptions and polluti...
A. Turn left directly B. Wait for a few seconds and then turn left C. Ignore the arrow and go straight D. Reverse and then turn left 相关知识点: 试题来源: 解析 A。解析:当左转交通信号为绿色箭头时,车辆可以直接左转。选项B等待几秒再左转不符合规则。选项C忽视箭头直接直行是错误的。选项D倒...
This paper discusses a method for optimizing the semi-actuated traffic signal control system by adjusting the initial interval according to the number of vehicles waiting for the green light in the actuated phase. We also present a Left-Turn actuated traffic signal control strategy that examines the...
This could have been the universal left turn signal for all left turns from exclusive lanes if allowed. Care must be taken to preventSecond Yellow Trap. This signal face can be changed by a timer or computer among three modes: Exclusively permitted* mode ...
the capacity of heavily congested intersections is presented: this approach opens up exit lanes for left-turn traffic dynamically with the help of an additional traffic light installed at the median opening (the presignal); this situation is referred to as exit lanes for left-turn (EFL) control...
When you turn right, you must keep close to the right-hand roadside or right-hand curb. Moving to the center lane and waiting for traffic to clear would be dangerous and usually illegal. Proper Right Turns For a right turn, you must signal well ahead of the turn, slow down, check blin...
