本发明涉及城市道路技术领域，尤其是涉及一种城市道路十字路口。The invention relates to the technical field of urban roads, in particular to an urban road intersection.
背景技术Background technique
城市道路十字交叉路口的交通拥堵问题和车辆、行人安全问题是一种现代城市通病，也已成为一个世界难题。The problem of traffic congestion at urban road intersections and the safety of vehicles and pedestrians is a common problem in modern cities and has become a worldwide problem.
十字路口车辆拥堵使车辆停留，造成资源浪费和环境污染。为改善拥堵，通过立交桥、高架桥和地下通道等方式分流到各个方向，但是无论哪一种分流方式的造价都十分昂贵，而有些十字路口己形成无法拆迁，特别是具有城市特色的古建筑根本无法动迁，造成不可避免的拥堵的难题。另外，在十字路口的人行通道上，常见到行人在人行红绿灯是红灯时强行过马路现象，十分危险。为此，不少城市聘请了交通协管员在十字路口引导行人过马路，但这无疑造成了人力资源的浪费。Vehicle congestion at intersections causes vehicles to stop, resulting in waste of resources and environmental pollution. In order to improve congestion, divert traffic to various directions through overpasses, viaducts, and underground passages, but the cost of any diversion method is very expensive, and some intersections have been formed and cannot be demolished, especially ancient buildings with urban characteristics. Relocation, resulting in inevitable congestion problems. In addition, on the pedestrian passage at the intersection, it is common to see pedestrians crossing the road forcibly when the pedestrian traffic light is red, which is very dangerous. For this reason, many cities have hired traffic coordinators to guide pedestrians to cross the road at crossroads, but this has undoubtedly caused a waste of human resources.
现有城市道路十字路口主要现状：一种是设有专用左转信号和右转信号，左转和右转通行时间各占一个通行周期的30%左右，影响通行能力30%以上；另一种是左转和直行车辆混合通行，左转车辆首先减速或停车，再穿过对向直行车道时，造成直行车道和对向直行车道的车辆减速停车，影响通行能力30%以上，如左转车辆较多时降低通行能力更多，还经常造成堵车；红灯时右转车辆插入另一个方向直行车道时，直行车辆不得不减速造成另一个直行车道通行能力降低。并且现有的十字路口非机动车通行也存在一些问题，通行不规范。The main status of existing urban road intersections: one is that there are special left-turn signals and right-turn signals, and the left-turn and right-turn traffic time each accounts for about 30% of a traffic cycle, affecting more than 30% of the traffic capacity; the other It is a mixture of left-turning and straight-going vehicles. When the left-turning vehicle first slows down or stops, and then passes through the opposite straight lane, it will cause the vehicles in the straight lane and the opposite straight lane to slow down and stop, affecting more than 30% of the traffic capacity, such as left-turning vehicles. When it is more, the traffic capacity is reduced more, and it often causes traffic jams; when the right-turning vehicle is inserted into the through lane in the other direction at a red light, the straight vehicle has to slow down and the capacity of the other through lane is reduced. And there are also some problems in the existing crossroads for non-motor vehicles, and the traffic is not standardized.
