Problems solved by technology

Furthermore, our country has a large population and a complex traffic environment. When the tram passes through a level crossing, the conflict with social vehicles greatly reduces the operating efficiency of the vehicle, and there are many safety hazards. Copying foreign tram technology cannot solve the problem in our country. Existing Problems
The patent of Harbin Institute of Technology "A Tram Priority Control Method Considering the Increased Upper Limit of Vehicle Delay in Non-Priority Phase" considers the delay of vehicles in non-priority phases, and thus adopts an optimization strategy. " and other articles mentioned the calculation of signal priority parameters and the introduction to control, but they did not classify and discuss the different walking modes of trams to obtain different control schemes.

Embodiment Construction

[0034] Attached below figure 1 to attach Figure 5 The present invention will be further described.

[0035] Laying detectors: Before entering the level crossing, install the forecast detector, request detector, stop line detector, and cancel detector in sequence along the driving direction of the tram to obtain information such as the position and speed of the tram. When the vehicle arrives at the forecast detection The signal control system judges the time when the tram arrives at the stop line through the real-time information of the train sent by the forecast detector, determines the priority plan according to the system model and current traffic information, and obtains the information whether to allow the vehicle to pass first. When the tram arrives at the request detector, the vehicle and the request detector jointly send out request priority information, which is transmitted to the signal control system. After receiving the information, the signal system sends the obt...

Abstract

The invention provides a single tramcar intersection crossroad synergistic priority control method. According to the invention, in the face of the problems in the prior art that a modern tramcar signal control system is complex, that the passing efficiency through an intersection crossroad is low, that the interference from the intersection crossroad is great in amount, and that safety hazards exist due to the mixed passing with social cars, a control strategy featuring the relative priority of the single tramcar in different traveling modes at an intersection crossroad is proposed. With an ordinary four-phase intersection crossroad as a research object and on the basis that the tramcar is ensured to pass first, the influence on social cars can be minimized. Compared with the strategy of controlling the lengthening of the green light, the early disruption of the red light or the phase spanning, the strategy of inserting a priority phase is adopted to increase the passing efficiency through the intersection crossroad in special conditions so that the tramcar can be operated at high efficiency, in security and with convenience.

Description

technical field [0001] The invention relates to a tram priority control method, which belongs to the field of urban traffic control. Background technique [0002] As an environment-friendly urban rail transit system with the advantages of low construction cost, short construction period, energy saving and comfort, tram has been widely used in developed cities abroad. Compared with foreign countries, trams are still a new thing in China, and the technology is still in its infancy, and it does not have complete regulations and operating plans like foreign countries. Furthermore, our country has a large population and a complex traffic environment. When the tram passes through a level crossing, the conflict with social vehicles greatly reduces the operating efficiency of the vehicle, and there are many safety hazards. Copying foreign tram technology cannot solve the problem in our country. Existing Problems. The patent of Harbin Institute of Technology "A Tram Priority Contro...
