Problems solved by technology

[0003] Trams run on urban roads, and their punctuality and reliability are not easy to guarantee compared to subways and light rails with closed lanes
Although generally trams operate on dedicated lanes, enjoy space priority, and are less disturbed by social vehicles and non-motorized vehicles, when they run in the range of intersections with public transportation, the distance between trams and other social vehicles right of way conflict

Embodiment Construction

[0022] The behavior of any vehicle passing through the intersection is marked by the action of passing through the shared or conflicting section of the road intersection. Vehicles and pedestrians in all directions can pass through the vehicle intersection according to certain rules, and trams have priority. The most important thing is that when the tram arrives at the level intersection, according to the principle of priority passing, the tram enjoys the right to pass directly without stopping and waiting. However, this priority will disrupt the normal order of public transport as the density of trams increases. How to achieve a balance between the two requires a procedure to balance the relationship between the two.

[0023] In general, the factors affecting traffic at level intersections are as follows:

[0024] The shape of the level intersection is a cross, a T-shaped intersection, or a cross that is larger than a cross.

[0025] The distribution of vehicle running chann...

Abstract

The invention discloses a priority selection method for passing of a tramcar at an intersection. The method comprises the steps of collecting information of geometrical shapes and lane distribution information of the intersection, arranging the lanes allowing the tramcar to pass through in a middle area of a sharing area of the intersection, detecting whether the tramcar approaches or not at the intersection in real time, controlling traffic signal lamps to open priority passing signals of corresponding levels to the tramcar, forbidding other buses to pass through the sharing area, sending the signals that the tramcar has passed through the intersection to a traffic signal lamp control system when a tramcar signal system detects that the real-time traveling position of the tramcar is out of the sharing area, returning prior occupied road rights, and recovering normal traffic. According to the priority selection method for the passing of the tramcar at the intersection, the tramcar can has the priority to pass through the intersection when passing the plane intersection of public transport, and passing of social vehicles on an opposite road cannot be influenced or influenced slightly at the same time.

Description

technical field [0001] The invention relates to a selection method for priority occupancy of the right of way applied to urban streetcar mixed level intersections. Background technique [0002] Tram is a green and fast way of urban rail public transportation. Compared with conventional buses, it has the advantages of large transportation volume, fast speed, high punctuality, and no exhaust emissions; compared with subways, it has the advantages of small investment and short construction period. In recent years, tram projects have begun to be built in some 2nd and 3rd tier cities or the suburbs of 1st tier cities in my country. [0003] Trams run on urban roads, and their punctuality and reliability are not easy to guarantee compared with subways and light rails with closed dedicated lanes. Although generally trams run on dedicated lanes, enjoy space priority, and are less disturbed by social vehicles and non-motorized vehicles, when they run in the range of level intersect...
