The invention discloses a method and device for improving road safety through an adaptive traffic signal lamp. The method comprises the steps of obtaining traffic flows in four directions of a crossroad; adding the traffic flow in the first direction and the traffic flow in the third direction in one lamp time to obtain a first traffic flow, wherein one lamp time is the time when the color of the traffic light is kept unchanged; adding the traffic flow in the second direction and the traffic flow in the fourth direction within one lamp time to obtain a second traffic flow; and according to the first traffic flow and the second traffic flow, adjusting the lamp time in the first road direction and/or the lamp time in the second road direction. According to the invention, the problem that the traffic flow in a certain direction cannot be increased suddenly due to the fixed arrangement of the traffic signal lamp in the prior art is solved, the adaptability of the traffic signal lamp is improved, and the traffic jam is relieved to a certain extent.
本申请公开了一种自适应交通信号灯提高道路安全的方法和装置,该方法包括:获取十字路口四个方向的车流量;将一个灯时内的第一方向和第三方向的车流量相加得到第一车流量,其中,一个灯时是红绿灯维持颜色不变的时间;将一个灯时内的第二方向和第四方向的车流量相加得到第二车流量;根据第一车流量和第二车流量,对第一道路方向上的灯时和/或对第二道路方向上的灯时进行调整。通过本申请解决了现有技术中交通信号灯固定设置无法解决某个方向车流量突发增大的问题,提高了交通信号灯的自适应性,在一定程度上缓解了交通拥堵。
