Embodiment

[0028] Take the intersection of Taiping North Road and Zhujiang Road in Nanjing as an example. The cycle time of this intersection is 160s, and the entrance road has 4 lanes, which are two dedicated left-turn lanes, one straight lane and one straight right lane. The steps for determining the length of the lane change prohibition on the entrance road of the intersection are as follows:

[0029] 1. The first survey point is 100 meters away from the parking line on the entrance road. During the off-duty peak (5:00-6:00 pm), the traffic of large vehicles and small cars passing through this point is surveyed at 5-minute intervals. Quantity V 1 and V 2 , and the number of vehicles Q when the car follows the car in consecutive time periods 1 , the obtained raw data are shown in Table 1, and the sorted data are shown in Table 2.

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 rate caused at the intersection entrance, and saves resources.

Description

technical field [0001] The invention relates to a method for determining the length of lane lines forbidding changing lanes at the entrance of an intersection in the field of road traffic marking in traffic engineering. Background technique [0002] It is forbidden to change lane lines, and it is set on bridges, tunnels, curves, ramps, road width gradient sections, intersection entrance roads, sections close to pedestrian crossing lines or other sections that are considered to be prohibited Lane changing section, its function is to prohibit vehicles from changing lanes and overtaking. The line that is prohibited from changing lanes is a solid white line. The width of the line is the same as the dividing line, which is 15cm. It is marked on the road section and connected to the white dotted line. When a motor vehicle is merging or changing lanes, it is only allowed at the dotted line. Connecting solid lines are not allowed. [0003] At present, in the traffic control system...
