Embodiment 1

[0028] The embodiment of the present invention provides a method of evaluating the time accuracy required to predict the time of the signal of the signal, evaluating the predictive vehicle to reach the target position and the accuracy of the time required to pass the time required for the vehicle in the signal light control section. ,like figure 1 and figure 2 As shown, including:

[0029] Step S101: Gets the travel information of each vehicle on the current segment, the travel information includes the position information, speed information, the signal information, the signal light information including the signal, and the state information, and duration information of the signal. In the current section, it can be a road segment with a vehicle tracking detection device, in particular, such as figure 2 As shown, it is possible to set an intersection of the signal light control, and the vehicle travels on this section, and when the intersection is reached, the state is advanced or ...

Embodiment approach

[0053] As an alternative embodiment of the present invention, the method also includes:

[0054] Step S108: When there is a second vehicle in front of the first vehicle, when there is no signal light, it is determined whether or not the speed of the second vehicle is zero; in the present embodiment, the first vehicle can be J2, accordingly, the second vehicle is The vehicle J1 running in front of J2, at this time, there is a motor vehicle in front of J2, and there is no signal light; the first vehicle may also be J3, according to the second vehicle, can be a vehicle J2 traveling in front of J3; judging the second vehicle Whether the speed is zero.

[0055] Step S109: When the speed of the second vehicle is not zero, according to the position information of the second vehicle, the speed information, and the interval distance of the first vehicle and the second vehicle, the third time of the first vehicle arrives at the target position YW; In the present embodiment, when the travel ...

Embodiment 2

[0078] The embodiment of the present invention provides an apparatus for evaluating the time accuracy required for the vehicle through the signal of the signal, and is applied to the vehicle on the signal light control section, evaluate the predicted vehicle to reach the target position and the accuracy of the time required to pass the time through the intersection. ,like Figure 4 As shown, including:

[0079] The first acquisition module 21 is configured to obtain travel information, target position information, and signal light information of each vehicle on the current segment, and travel information includes position information, speed information, and signal light information including signal lights, location information, and duration information. Detailed implementation can be refer to the related description of step S101 in the above method embodiment.

[0080] The first determination module 22 is configured to determine whether the first vehicle is present in front of whet...

Abstract

A method and device for evaluating and predicting the accuracy of time required for a vehicle to pass through a signal light intersection provided by the present invention, comprising: obtaining the driving information, target position information and signal light information of each vehicle on the current road section; judging whether there is a second vehicle in front of the first vehicle And signal lights; when there is a second vehicle in front of the first vehicle and there is a signal light, judge whether the speed of the second vehicle is zero; when it is not zero, judge the state of the signal light in front of the second vehicle; , calculate the first time when the first vehicle arrives at the target position; obtain the second time when the first vehicle actually arrives at the target position; calculate and predict the time accuracy for the first vehicle to reach the target position according to the first time and the second time. By implementing the present invention, it is possible to accurately evaluate the prediction of the passing time of vehicles, and to control signal lamps based on the evaluation results, thereby effectively relieving the traffic pressure at signal lamp-controlled intersections.

Description

Technical field [0001] The present invention relates to the field of intelligent transportation, particularly to a method and apparatus for evaluating the accuracy of the predicted time required for the vehicle by light intersection. Background technique [0002] In order to improve the efficiency of the intersection traffic signal control, to ensure the safety and smooth flow of people travel, traffic administration department is very concerned about the forecasting techniques of the time required by motor vehicle traffic light intersection, by predicting the results to establish the necessary means to respond to future traffic trends. Therefore, how to ensure the accuracy of the predicted time required by motor vehicle traffic light intersection control to evaluate a problem to be solved. Inventive content [0003] Accordingly, the present invention is to overcome the technical problem of accuracy can not predict the time required by the vehicle signal control intersection pri...
