Problems solved by technology

[0004] First, when switching between peak, flat peak, and low peak control modes, timing, manual, or set flow thresholds are used to switch, and there are problems of intersection congestion or green light time loss caused by switching lag or advance; second, when a The queuing length of motor vehicles in the direction is too long, and when the platoon control method is required, manual assistance is generally required to guide the drivers into the platoon lane, and the automatic mode cannot be used to guide the driver into the prescribed lane in an orderly manner; Detect whether all the vehicles released by this phase are empty in the formation area and switch to the next phase in time after emptying

Embodiment 1

[0077] This embodiment provides a method that can ensure the precise operation of the platoon traffic organization, including the following steps:

[0078] S1: Plane accurate and continuous tracking of motor vehicles in each direction of the intersection, and obtain the number of motor vehicles in each direction and the precise position of each motor vehicle in real time;

[0079] S2: Obtain the highest number of waiting times K1 for stopping when encountering a red light in the first direction and the highest number K2 for waiting for stopping when encountering a red light in the second direction;

[0080] S3: Judging whether the highest number of waiting times for stopping at a red light in the first direction is equal to the highest number of waiting times for stopping at a red light in the second direction, if they are equal, go to step S4, otherwise go to step S5;

[0081] S4: Judging whether the maximum number of times of stopping at a red light is zero, if it is zero, t...

Embodiment 2

[0123] In this embodiment, on the basis of Embodiment 1, the following improvements are made. The precise and continuous tracking of the plane described in step S1 includes the following steps:

[0124] S11: set several plane detectors on the intersection, the plane detectors are used to continuously track motor vehicles; mark the detection range of the detectors, the upstream section of the signal light, and the downstream section of the signal light on the electronic map with latitude and longitude , and the position coordinate data of the detector (X j ,Y j ), the position coordinate data of the signal light (X x ,Y x ) marked on the electronic map;

[0125] S12: Obtain the current detection error of the detector (X c ,Y c ), judge the current detection error (X c ,Y c ) is within the set threshold range, if so, then enter step S13, otherwise an alarm signal is sent, indicating that the coordinate data of the correction marker position cannot be accurately obtained, ...

Embodiment 3

[0151] This embodiment provides a system that can ensure the precise operation of the platoon traffic organization mode, such as Figure 7 shown, including

[0152] The plane tracking unit 1 performs plane precise and continuous tracking on the motor vehicles in each direction of the intersection, and obtains the number of motor vehicles in each direction and the precise position of each motor vehicle in real time;

[0153] The number of parking times acquisition unit 2 is used to obtain the highest number of waiting times K1 for stopping when encountering a red light in the first direction and the highest number of waiting times K2 for stopping when encountering a red light in the second direction;

[0154] The first judging unit 3 judges whether the highest number of times of waiting for stopping when encountering a red light in the first direction is equal to the highest number of times of waiting for stopping when encountering a red light in the second direction;

Abstract

The invention discloses a method and system capable of guaranteeing the precise running of an array-type traffic organization mode, and the method comprises the steps: determining that a current intersection is in a high peak state, in a flat peak state or in a low peak state according to the maximum number of waiting times during red lights, so as to carry out the call of a corresponding signal lamp control scheme; improving the control efficiency of signal lamps through prolonging the period of signal lamps and adjusting the green ratio, determining that a current time period is a high-peak operation period when the numbers of waiting times in two directions during red lights are greater than three, employing an array-type regulation and control method for regulation and control in a direction where the number of waiting times is high when the number of waiting times of a motor vehicle in one direction during red lights is greater than the number of waiting times in the other direction during red lights, so as to improve the passing efficiency of the motor vehicle in the direction; moreover, carrying out the continuous tracking of the vehicle in real time in a process of an array-type regulation and control method, guaranteeing that the array-type regulation and control method can complete the regulation and control, so as to achieve an expected regulation and control effect.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a system and method capable of ensuring the precise operation of a platoon-type traffic organization. Background technique [0002] With the rapid development of the economy and the continuous expansion of the city scale, the motor vehicles have increased sharply. In order to ensure the safety and smoothness of the intersections, the management department usually installs signal machines at the intersections to control the orderly passage of motor vehicles. In order to improve the traffic efficiency of intersections, various control strategies under peak, flat peak and low peak traffic conditions are adopted to meet the control requirements under peak, flat peak and low peak traffic conditions. [0003] In order to further improve the control efficiency of signal lamps, a traffic control method and facilities are disclosed in the existing patent document CN1441...
