Method for setting road traffic signal and controlling crossing traffic

Abstract

The invention provides a method for road traffic signal setting and crossing traffic control. A stop line is arranged on the left-lane at the position one distance from the stop line at the crossing and a section of a central dividing line is erased to set an exit, the dividing line between a first and a second lanes or the dividing line between a second and a third lanes is changed into a full line to cause an exit lane in the opposite direction to be employed as an entrance lane for forward driving under the circumstance of time separation in each signal period. In addition, according to the status quo of relatively wide road lane in China, the lanes of a two-way road experience a compact design; entrance lanes are added and a bus crossing priority system is established to make full use of the time and space of the crossing traffic to improve the traffic capacity and traffic quantity of crossings, in particular effectively improve the operation effect of buses, thus leading to the free-flowing and speed-raising of the traffic, energy-saving and emission-reducing and safety and order of the traffic and the sustainable development of the traffic transportation of the whole city.

Description

technical field [0001] The invention relates to the setting of road traffic signals and a traffic control method at an intersection, belonging to traffic engineering and a traffic signal control method. Background technique [0002] Traffic lights, traffic signs, and traffic markings are important components of road traffic signals. The setting of the current road traffic signal is unreasonable, the road resources and traffic time are not fully utilized, the delay time of driving at the intersection is long, and the traffic capacity and traffic volume at the intersection are not large, making the intersection a bottleneck of traffic congestion and the cause of traffic accidents. Frequent occurrence, large energy consumption and pollution. It is mainly manifested in that, for example, on a two-way 6-lane road, when the traffic light is green, there are only one lane for going straight, one lane for left and one lane for right turn, while there are three exit lanes, which ser...

Third, according to the different signal schemes at intersections, if the signal scheme is to go straight in one direction, turn left and drive with a green light at the same time, the direction must be rotated counterclockwise. "lane" will conflict with incoming vehicles), so that in the same signal cycle, the time for pedestrians crossing the street in the left direction (pedestrian crossing time is within the green light time of straight vehicles in the same direction) will be relatively short, or pedestrians will encounter pedestrians crossing the street endlessly. The phenomenon of red lights or interlacing with oncoming vehicles poses a great safety hazard; if the signal scheme is to go straight in the opposite direction, turn left and drive with green lights at the same time, pedestrians and non-motor vehicles will not have time to cross the street. This method can only be applied to overpasses or facilities. The intersection of the underground passage; if the signal scheme is to turn left before going straight, the straight vehicles coming from the downstream, which account for the majority of the intersection, will be delayed more

The existing bus-only lanes cover the entire road, occupying a lot of road resources in urban areas, and many road conditions are limited and cannot be set up; bus stops are generally on the right, and you cannot turn left in the bus-only lanes when you reach the intersection. It is inconvenient and affects the overall traffic, and there are also potential safety hazards

At present, the special signal lights for buses at the intersection indicate that the bus passing the intersection is a special phase, which takes up a lot of right-of-way time at the intersection, causing other traffic to delay longer at the intersection, which has a great impact on the overall traffic speed in the urban area and increases traffic consumption. energy and pollution

[0007] The current or published road traffic signal settings and traffic control methods generally result in more delays for driving at intersections, which makes it difficult to fundamentally alleviate the problems of urban road traffic congestion, large energy consumption and pollution, and many accidents
