The invention relates to a safe and fast traffic law scheme which has a lower cost and is associated with city
road construction, motor vehicles, non-motor vehicles, pedestrians, animals and the like. The scheme is characterized in that motor vehicle lanes are divided into low-speed lanes at levels 0, 1, 2 and 3, intermediate-speed lanes at levels 4, 5 and 6 and high-speed lanes at levels 7, 8, 9 or higher; and man-vehicle separation guardrails are arranged so that the occurrence of traffic accidents is greatly controlled by means of the man-vehicle separation. The roads at different levels are intersected, the roads at same level are not intersected, the roads at odd-even levels are intersected, the roads at odd levels are not intersected and the roads at even levels are not intersected; and simply constructed flyovers occupy small floor space and have lower height so that the security is enhanced and the construction cost is saved. The junctions are divided into three-road junctions, T-shaped junctions, crossings (with monitoring systems), annular junctions, junctions with five roads, six roads, seven roads, eight roads, nine roads and above, and the like. The traditional motor vehicle
signal lamps, non-motor vehicle
signal lamps and
pedestrian crossing
signal lamps are cancelled so that the time is saved and the efficiency is improved. At the T-shaped junctions and the crossings, the motor vehicles can run according to the
arrival time; the right-turn motor vehicles allow the straight-through motor vehicles to run first; if two motor vehicles going straight arrive at a waiting line at the same time, the motor vehicle on the road at the lower level allows the motor vehicle on the road at the higher level to run first; therefore, the city traffic runs safely, orderly and rapidly. The non-motor vehicles, the pedestrians, the animals and the like advance on the non-motor vehicle lanes and the sidewalks and utilize skywalks and underground passages for crossing roads.
