Embodiment Construction

[0055] Attached below figure 1 to attach Figure 8 To further illustrate the present invention, this control strategy considers that two trams arrive at a level crossing and pass through preferentially relative to social vehicles, and carry out different combinations and classifications according to different walking modes. The implementation process is described in the following classifications.

[0056] 1. Detector layout

[0057] In front of the level crossing, along the direction of the tram, the warning detector, the request detector, the stop line detector, and the cancellation detector are installed sequentially, mainly to obtain information such as the position and speed of the tram. Among them, the forecast detector sends the vehicle information to the signal control system when it detects the arrival of the vehicle, so that the signal control system calculates the time required for the vehicle to reach the stop line, and determines the priority scheme according to t...

Abstract

The invention provides a cooperative priority control method of double tramcars at a level crossing under a non meeting state. The invention provides a phase position control method of signal lights when two tramcars reach the level crossing in the states except for the meeting state by considering the condition that the tramcars and social vehicles run together at the level crossing. According to the invention, by separating conflicting vehicles based on time, obeying the principle of let the tramcars relatively preferentially go and vehicles free from the conflict go simultaneously, and adopting the control strategies of green-light extension, red-light early stopping, phase position insertion and phase position crossing, mutual conflicts of two types of vehicles are reduced and passing efficiency of the level crossing is improved.

Description

technical field [0001] The invention relates to a coordinated priority control method for double tramway crossings, which belongs to the field of urban traffic control. Background technique [0002] For a country like my country, which lacks many resources, the development of public transportation with low energy consumption, safety and environmental protection is the only way to solve the transportation problems in the development of urbanization, and modern trams are reliable, comfortable, energy-saving and environmentally friendly. in line with this development goal. However, due to the large conflict between the operation of trams and social vehicles, especially at level crossings, only by solving this problem can the safe operation of road mixed traffic be guaranteed. Li Sheng of Tongji University mentioned multi-level coordinated control in "Modern Tram and Road Traffic Coordinated Control Method", and carried out calculation and verification of the model; Based on tw...
