Problems solved by technology

[0004] But at present, the control methods of variable lanes are mainly manual control or timing control. The manual control mode requires a lot of human resources, while the timing control mode cannot keep up with the real-time road traffic demand. Both of them have hysteresis, traffic and social benefits Inferior disadvantages

Embodiment Construction

[0064] The present invention will be further described below in conjunction with specific examples.

[0065] The basic idea of ​​the method for dynamic control of tidal lane driving direction in the present invention is to input road basic data, real-time traffic flow rate and predicted number of vehicles in line, judge the road traffic operation status according to the saturation of the two directions, and Call the corresponding control model to solve the optimal control scheme, judge whether the optimization condition is satisfied, if it is satisfied, output the optimal scheme G1 to the road infrastructure for execution, otherwise output the existing scheme G0, the method of the present invention can realize the high speed of the variable lane driving direction. Efficiency switching.

[0066] Such as figure 1 As shown, the dynamic control method for the direction of travel of the tidal lane comprises the following steps:

[0067] 1) Basic data preparation: length of tidal ...

Abstract

The invention discloses a tidal lane driving direction dynamic control method. The method comprises the steps that road basic data, real-time traffic flow rate and predicted number of queue vehicles are input; according to saturation in two directions, road traffic conditions are divided into five modes; according to a corresponding condition, a corresponding control model is called to solve an optimal control scheme; whether the optimal control scheme meets an optimization condition is determined; and if the optimal control scheme meets the optimization condition, the optimal scheme is output to road infrastructure and is carried out, otherwise the existing scheme is output. According to the invention, a model which dynamically changes the driving direction of a lane according to the real-time traffic flow rate and the predicted number of queue vehicles is provided for the first time; the method is suitable for a variable-lane road with more than 2 lanes; and the method has the advantages of high road resource utilization, good economic benefit, being universal and the like.

Description

technical field [0001] The invention relates to the technical field of road traffic control, in particular to a method for dynamic control of the driving direction of a tidal lane, which can be used for scheme decision-making in the process of dynamic control of the driving direction of the tidal lane. Background technique [0002] In recent years, with the rapid development of the national economy, the process of urbanization has accelerated, and affected by the urban planning layout and the increase in land value in the central area, it has gradually formed a situation where the working units are concentrated in the central area of ​​the city and the place of residence is mainly concentrated in the suburbs of the city. There is an obvious tidal traffic phenomenon in which a large number of motor vehicles enter the city in the morning peak and a large number of motor vehicles leave the city in the evening peak, which makes the allocation of road resources unreasonable on con...
