Embodiment 1

[0052] Refer to the attached figure 1 , a method for controlling variable lanes based on navigation information of this embodiment, comprising the following steps:

[0053] S1. Lane-level traffic detection: identify and detect the traffic flow and queue length of each lane at the current intersection and upstream intersection through image recognition methods and vehicle detection algorithms. The identified content includes vehicle position, vehicle type, vehicle speed, and license plate number , distance between vehicles and vehicle queuing length, and every T1 time, calculate the flow and queuing length of each lane group during this period;

[0054] S2. Estimation of travel time between intersections: use the interval time between vehicles with the same license plate identified at the upstream intersection and the current intersection to calculate the travel time between intersections;

[0055] S3. Acquisition of vehicle navigation information: use roadside equipment in co...

Embodiment 2

[0082] In step S3, a GPS navigation software access system is installed on the roadside of the intersection. The GPS navigation software access system can connect to the GPS navigation software in the vehicle owner's terminal through wireless communication to obtain the current GPS navigation information of the vehicle owner to obtain the position of the vehicle at the upstream intersection. and navigation information such as Figure 4 shown.

[0083] The specific implementation scenario is: through the GPS navigation software access system connected with the GPS navigation software, when some car owners use the GPS navigation software, they can obtain the route information pushed by the software to the car owner, so as to know the driving direction information of the vehicle at the intersection, and can accurately Acquiring vehicle location and other information is more convenient to use and reduces the work of predicting and calculating the number of vehicles. It can also di...

Abstract

The invention discloses a variable lane control method based on navigation information, specifically relates to the field of traffic management, comprising the following steps: S1, lane-level flow detection; S2, estimation of travel time between intersections; S3, acquisition of vehicle navigation information; S4 . Steering traffic flow forecast; S5. Generation of variable lane scheme: According to the predicted number of vehicles traveling in each direction, the number of lanes in each direction, and considering the difference in passing time of vehicles traveling in different directions, determine the direction of the variable lane. The invention utilizes the vehicle-road cooperative communication mechanism to obtain the predetermined driving direction of some vehicles when passing a certain intersection, and use it for the control of the variable lane, and the accuracy of the acquired data is high, and the basis for adjusting the variable lane is more reliable and variable The adjustment of the lane tends to be more reasonable.

Description

technical field [0001] The embodiment of the present invention relates to the field of traffic management, in particular to a variable lane control method based on navigation information. Background technique [0002] With the increasing number of motor vehicles in our country, traffic congestion is becoming more and more serious, especially as the node of urban traffic, the intersection is an important part of the urban road system. pivotal role. Under the influence of tidal traffic, many intersections will produce unbalanced flow directions, which will easily lead to low utilization efficiency of entrance roads and cause congestion. [0003] In order to make full use of road resources and improve road traffic capacity, many cities now have variable lanes at intersections. The control method of variable lanes is mainly switched by manual observation of road conditions, or switching at a fixed time based on historical data statistics. The efficiency of manual switching is ...
