Problems solved by technology

However, the existing technical solutions simply provide congestion information on each road section, but do not provide information on stranded vehicles at traffic intersections and information on the status of nearby traffic lights. The information provided is limited and the reference value is general.
There are still some information distribution schemes based on intersection image recognition in the prior art, but the reliability is not high because the influence of foggy weather is not considered

Embodiment Construction

[0033] The implementation of the data acquisition system implementing the traffic data acquisition method at the intersection where the signal light is located will be described in detail below with reference to the accompanying drawings.

[0034] An intersection with signal lights is generally the intersection of two or more roads. This is the necessary place for vehicles and pedestrians to gather, turn and evacuate, and it is the throat of traffic. Therefore, the correct design of road intersections, the rational organization and management of intersection traffic are important aspects of improving road capacity and ensuring traffic safety. Road intersections are divided into level intersections, roundabouts and level intersections. Level intersections are intersections where roads intersect on the same level. Usually there are T-shaped, Y-shaped, cross-shaped, X-shaped, dislocation, ring and other forms. A roundabout is to set a larger roundabout (central island) in the ...

Abstract

The invention relates to a traffic data collecting method of a crossing where a signal lamp is located. The method comprises the steps that the crossing where the signal lamp is located is shot with a CCD visual sensor to obtain a crossing image; sharpness processing is performed on the crossing image with a haze removing processor to obtain a sharpness crossing image; image processing is performed on the sharpness crossing image with a congestion index analyzer to obtain a crossing congestion index; signal lamp information is collected in real time with a signal lamp data collector; the crossing congestion index and signal lamp information are obtained with an AT89C51 single chip microcomputer, wherein the AT89C51 single chip microcomputer is connected with the congestion index analyzer and the signal lamp data collector. According to the traffic data collecting method of the crossing where the signal lamp is located, accurate collecting of the traffic data of the crossing where the signal lamp is located under all kinds of weather can be guaranteed, and important evidence is supplied to information issue of local traffic management departments.

Description

[0001] The present invention is a divisional application of a patent with the application number 201510164694.7, the application date is April 8, 2015, and the invention name is "method for collecting traffic data at intersections where signal lights are located". technical field [0002] The invention relates to the field of information collection, in particular to a method for collecting traffic data at intersections where signal lights are located. Background technique [0003] In urban road driving, the place where the car spends the most time from the departure point to the destination is not in the normal driving stage of the road, but in the stage of waiting for lights at road traffic intersections or being blocked near road traffic intersections. With the advancement of science and technology and the improvement of people's living standards, the progress of urbanization continues to expand, there are more and more vehicles in the city, and urban roads are becoming mor...
