Method and device for controlling passing of rail vehicles at level crossing under half-exclusive right-of-way

Abstract

The invention provides a method for controlling the passing of rail vehicles at a level crossing under half-exclusive right-of-way. The method includes the following steps: reading the time t0 when arail vehicle arrives at the beacon of a level crossing and the phase cycle composition Tnow(t0) and the working state of a signal control machine at the level crossing at the time t0; determining thevalue range of the delay time t in opening the rail vehicle passing route according to the time t0, the phase cycle composition Tnow(t0) and the working state; calculating the delay time f(t0, t) of arail vehicle passing the level crossing and the delay time d(t0, t) increased by social vehicles at the level crossing; calculating the efficiency value e(t0, t) according to the delay time f(t0, t)of the rail vehicle passing the level crossing and the delay time d(t0, t) increased by social vehicles at the level crossing, determining that t=td, and maximizing the efficiency value e(t0, t); andopening the rail vehicle passing route after a delay of the time td, and adjusting the operation cycle of the level crossing according to the time td. The delay caused by tramcars to the social traffic can be minimized while the operation efficiency of tramcars is maximized, and the integration of tramcars and road vehicles can be promoted.

Description

technical field [0001] The present invention relates to a control method and device for a rail vehicle, and more specifically, to a method and device for controlling the passage of a rail vehicle at a level crossing under a semi-exclusive right of way. Background technique [0002] Under the semi-exclusive right of way, the level crossing is the only area where trams interact with social vehicles, which affects the operation and service level of trams. Therefore, it is necessary to give priority to trams at level crossings. However, trams Priority will inevitably affect the delay time of social vehicles at level crossings, so it is necessary to balance the contradiction between trams and social vehicles at level crossings. [0003] Patent application CN201610890925.7 proposes an intersection traffic control method based on the tram active operation control system. By actively controlling the speed of the tram, the moment when the tram arrives at the level crossing is just at...

Problems solved by technology

The idea of ​​this paper is to formulate a tram signal priority scheme for the offline coordination of tram multi-intersections. , "Phase Insertion" as a backup plan in order to maximize the operating efficiency of trams, but this concept also fails to maximize the balance between trams and social vehicles at level crossings, and once a train of trams appears Deviating from the coordinated traffic priority scheme during operation will have an impact on the subsequent tram coordinated traffic priority scheme
