Problems solved by technology

[0002] In daily life, traffic jams are often encountered. The time of traffic lights at traffic intersections is fixed, and the situation of large traffic cannot be unblocked in time. The number of vehicles passing through within the effective time is limited, which brings inconvenience to people's travel.

Embodiment Construction

[0019] Below in conjunction with embodiment the present invention is further explained.

[0020] A method for dynamically adjusting the time of traffic lights at intersections based on big data, comprising the following steps:

[0021] Step 1, obtain information such as traffic volume and queuing volume in two directions at each crossroad at different times, and the traffic speed, traffic volume, queuing volume and other information in step 1 can be obtained through the urban road monitoring system;

[0022] Step 2. Obtain information such as the distance between adjacent intersections at the same time, the speed of traffic in the same direction, the volume of traffic, and the amount of queuing. Based on the same historical weather, the same time, the same location, and the traffic flow information at adjacent intersections, combined with the current actual traffic volume The information is analyzed and calculated in real time to obtain traffic light traffic and waiting time; ...

Abstract

The invention provides a crossroad traffic light time dynamic adjusting method based on big data. The crossroad traffic light time dynamic adjusting method comprises the following steps that 1, information such as traffic flow and queue-up quantity in two directions of all crossroads at different moments is obtained; 2, information such as the distances between the adjacent crossroads at the samemoment and traffic speed, traffic flow and queue-up quantity in the same direction is obtained; 3, information such as weather conditions of different crossroad positions is obtained; 4, all the information is uploaded to a cloud server; 5, a jamming state is predicted; 6, the cloud server simultaneously collects actual onsite jamming states in real time; 7, green-light passing and red-light waiting time in two directions of a crossroad is adjusted in time according to optimized adjusting results; and 8, all the information can be issued in real time through a network. By means of the crossroad traffic light time dynamic adjusting method based on big data, traffic light time can be dynamically adjusted, and traffic jamming is reduced.

Description

technical field [0001] The invention relates to the field of traffic technology, in particular to a method for dynamically adjusting the time of traffic lights at crossroads based on big data. Background technique [0002] In daily life, traffic jams are often encountered.
