Abstract

The embodiment of the invention provides a control apparatus and method of crossing signal lamps. The apparatus comprises a detection unit used for detecting the congestion states of a first direction road and a second direction road aiming at a predetermined area in monitoring images of the first direction road and the second direction road; a counting unit used for respectively counting vehicles passing through the first direction road and the second direction road in the predetermined area within a predetermined time; and a control unit used for controlling the signal lamps of the first direction road and the second direction road according to the congestion degrees of the first direction road and the second direction road, the weights of the first direction road and the second direction road, and the number of the vehicles passing through a crossing, of the first direction road and the second direction road within the predetermined time based on the congestion states of the first direction road and the second direction road. According to the apparatus and method, the response is rapid, the estimation is accurate, the signal lamps can be rapidly and effectively controlled, and the problem of traffic jam is effectively alleviated or solved.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a control device and method for a signal light at an intersection. Background technique [0002] With the development of cities and the improvement of living standards, the number of vehicles has increased year by year, and the problem of traffic congestion has become increasingly prominent. Therefore, the monitoring of road traffic conditions and the reasonable control of signal lights at intersections are one of the important means to solve the problem of traffic congestion. [0003] In existing methods, traffic congestion is usually estimated based on a simple vehicle counting method to control signal lights. [0004] It should be noted that the above introduction of the technical background is only for the convenience of a clear and complete description of the technical solution of the present invention, and for the convenience of understanding by those skilled in the a...
