Method for determining traffic lane length of crossing inlet road for forbidding lane exchange

Abstract

The invention discloses a determining method for banning changing the length of a lane line in an intersection entrance, which belongs to the field of road traffic marking in traffic engineering. The determining method comprises the steps: firstly the traffic data is acquired through a manual counting or photographic method, and the acquired total traffic volume is converted into equivalent standard car traffic volume; then, by adopting an M / M / N model in the queuing theory, the number of the queuing cars behind the parking line of the intersection entrance is calculated according to a multiple-channel queue system; and finally, the number of the cars is converted into car average queuing length at the unit of meter, and then added with the minimum safety distance among the queuing cars, so that the length of the banned changing lane line can be obtained. The method can avoid traffic jam at the intersection, increases the running efficiency of the intersection, reduces the failure ratecaused at the intersection entrance, and saves resources.

Description

technical field [0001] The invention relates to a method for determining the length of lane-changing prohibited lanes at intersections and entrances in the field of road traffic markings in traffic engineering. Background technique [0002] It is forbidden to change lanes, and it is set on bridges, tunnels, curves, ramps, road sections with gradually changing width of roadways, intersection entrance roads, road sections close to pedestrian crosswalks, or other road sections that are considered to be prohibited due to heavy traffic and multiple lanes in the same direction. The lane-changing section is used to prohibit vehicles from changing lanes and overtaking. It is forbidden to change lanes. The line is a white solid line with the same width as the dividing line, which is 15cm. It is marked on the road section and connected with the white dotted line. When merging or changing lanes, motor vehicles are only allowed to do so at the dotted line. Connecting solid lines are no...

AI Technical Summary

Problems solved by technology

Although this method is simple, on curves, ramps, especially at intersection entrances, if the length of the prohibition lane change line is too long, it will cause inconvenience to vehicles changing lanes, and even cause violations and illegal driving; If the length is too short, it will cause congestion of vehicles at the intersection, increase delays, reduce the efficiency of intersection traffic, and even lead to traffic accidents
