Due to the convenience brought by the traveling of the electric bicycles, the holding quantity and the traveling quantity of non-motor vehicles (including the electric bicycles) in many cities in China are rapidly increased in recent years, the phenomenon that the non-motor vehicles and the motor vehicles compete for the road is increasingly prominent, and particularly at the road intersection, the traffic accidents are very serious due to the influence of the factors that the passing space of the non-motor vehicles is limited, the riding is random and the like.
At present, the solution measures for the non-motor vehicle passing time and the non-motor vehicle passing space at the intersection are generally two: firstly, the traffic space and traffic signal lamps of the non-motor vehicles and the pedestrians are combined, namely the non-motor vehicles use pedestrian indication signals, pedestrian zebra crossings and pedestrian standing safety islands to pass. And secondly, a special non-motor vehicle passing signal lamp is arranged, a non-motor vehicle passing area with the width of about 4m is arranged between the motor vehicle stop line and the pedestrian zebra crossing, and the space and time separation among pedestrians, non-motor vehicles and motor vehicles is realized. However, both of the above solutions have disadvantages.
The first solution is deficient in that: the non-motor vehicles occupy large space and have high traveling speed, so pedestrian zebra crossings and safety islands often overflow, the normal traffic of the motor vehicles is seriously interfered, and great potential safety hazards exist. Meanwhile, serious conflicts exist between non-motor vehicles passing in two directions and between the non-motor vehicles and pedestrians.
The second solution is deficient in that: the non-motor vehicles are provided with special signals and street-crossing channels, so that the effective passing time of the motor vehicles and pedestrians at the intersection is seriously reduced, the occupied space of the intersection is serious, and the overall running efficiency of the intersection is seriously low. Meanwhile, serious traffic interweaving and conflict still exist among non-motor vehicles passing through the left turn, motor vehicles and pedestrians.
