Description
BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to an intersection traffic control system and an intersection having the control system, and in particular, to an intersection traffic control system which can reduce traffic violations and traffic accidents. Description of Related Art In an existing intersection traffic control system, a traffic signal light device 1s installed by the side of the lane after an intersection, as shown in FIG. 1. On one hand, as traffic congestion becomes increasingly serious in the city, when there are a lot of vehicles waiting at the intersection, the vehicles behind are far away from the traffic signal light; therefore, the drivers cannot effectively judge the traffic situation at the intersection ahead and thus are likely to change lanes at will, resulting in more serious congestion at the intersection. On the other hand, with the increasing number of near-sighted drivers nowadays, they cannot see clearly the traffic signal light at the intersection ahead due to their limited vision, and may misjudge the traffic situation at the intersection ahead, easily making a traffic violation such as running a red light. In addition, during waiting at a red light at the intersection, in a case where a vehicle, such as a large truck or a bus, that blocks the line of sight is in front of a small car, the driver in the small car cannot see the traffic signal light ahead of the intersection, resulting in the inability to effectively and timely know the current traffic situation. At present, the traffic signal light is composed of a light holder and a light pole, where the light holder includes a plurality of light holder units arranged in parallel, and each light holder unit includes a lamp assembly 11 and a back casing assembly 12, as shown in FIGs. 5-1 to 5-3. The back casings in the back casing assemblies are aluminum die-castings having identical structures and sectional dimensions, and are mutually fixedly connected (that is, contacting lateral plates of every two adjacent back casings are fixedly connected via bolts). The assembly of the back casing assemblies is complicated and a manual hole-making process is requited200002 resulting in a poor waterproof effect. The structure after assembly is complex and has a heavy weight, resulting in high production and mounting costs.
