Embodiment Construction
[0025] In order to illustrate the technical solutions of the embodiments of the present invention more clearly, the following briefly introduces the accompanying drawings used in the description of the embodiments. Obviously, the drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, other drawings can also be obtained from these drawings without any creative effort.
[0026] The purpose of the present invention is to make the bus not decelerate when it arrives at the signalized intersection, and to take priority over the social vehicles to exit the intersection. To achieve this purpose, a harbor-type bus stop must be set up, and a bus stop signal lamp should be set up at the platform. When the bus arrives at the harbor-style bus stop, the signal light of the bus stop is red, and the bus needs to stop at the station. When the signal light turns green, the bus leaves the harbor-style bus stop. When it rea...

The invention discloses a speed detection-based priority control method for bus line jumping at intersections, giving priority to buses in passing "space" and "time", giving priority to the right of way at intersections by using right-turn lanes in space, and giving priority in time Use the signal timing to guide the bus to leave the upstream bus station and leave the intersection without stopping. For signalized intersections with uncontrolled right turns, the bus enters the harbor-style bus platform from the upstream, and the bus platform signal light controls whether the bus drives out of the platform. If the signal light is green, the bus drives out of the platform. Turn right at the intersection and share the bus lane with the speed difference, and leave the signalized intersection before social vehicles. If the speed difference is insufficient, use the bus signal lights at the intersection to enter the intersection ahead of time and leave the intersection. The invention solves the problem of secondary parking of buses at intersections, reduces vehicle delays and parking times, reduces exhaust emissions of motor vehicles, and protects the environment.
Description
technical field [0001] The invention belongs to the field of urban road traffic signal control, and relates to methods for signal timing at intersections, bus priority and the like. Background technique [0002] At present, the main problem facing urban transportation is traffic congestion, and the main way to solve this problem is to give priority to the development of public transportation. The limited urban road resources and the rapid increase in the number of motor vehicles have seriously affected the development of public transportation. In many cities, the proportion of public transportation trips is very low, the service level cannot meet the needs of passengers, and the convenience of urban transportation has not been fully exerted. Especially at the node signal intersection of urban traffic, bus vehicles and social vehicles have the common driving right. Since the characteristics of high passenger load rate of bus vehicles are not taken into account, the total dela...
