Description

Intersection traffic control system and intersection containing the control system

Technical field

The invention relates to an intersection traffic control system and an intersection containing the control system, in particular to an intersection traffic control system that reduces traffic violations and traffic accidents.

Background technique

The existing intersection traffic control system generally installs a traffic signal light device beside the lane after passing the intersection, as shown in Figure 1. On the one hand, with the increasing traffic congestion in the city, when there are many waiting vehicles at intersections, the vehicles behind them cannot effectively judge the traffic situation at the intersection ahead because they are far from the traffic lights. They start to change lanes at will, resulting in more traffic congestion at the intersection. On the other hand, with the increasing number of myopic drivers nowadays, due to limited vision, myopic drivers cannot see the traffic lights at the intersection ahead, leading to misjudgment of the traffic situation at the intersection ahead, and traffic violations such as red light running. In addition, when the intersection is waiting for a red light, and there are vehicles that block the line of sight such as large trucks or buses in front of the small cars, the small cars behind cannot see the traffic lights in front of the intersection, resulting in the inability to effectively and timely understand the current traffic situation.

At present, the traffic signal lamp is composed of a lamp holder and a lamp pole. The lamp holder includes several lamp holder units arranged side by side. The lamp holder unit includes a wick assembly 11 and a rear housing assembly 12, as shown in Figs. 5-1 to 5-3; The back cover in the back shell assembly is a die-cast aluminum piece with the same structure and the same cross-sectional size, and the back covers are fixedly connected two by two (that is, the side plates of every two adjacent back covers are fixedly connected by bolts).
