Problems solved by technology

However, the SCATS system cannot obtain the queue length of each entrance at the intersection. At present, with the development of science and technology, there has been a device that can replace the coil for collecting traffic parameters in the SCATS system, that is, the video detector, and the video detector itself will also With license plate recognition function

Abstract

The invention relates to a method for constructing a queuing length model at a SCATS signal intersection based on video detection, including a video detector arranged behind the stop line at the entrance of the intersection, on the one hand replacing the original SCATS system coil for collecting traffic parameters, and on the other hand having license plate recognition Function. The technical solution of the invention is to provide a method for constructing a queue length model at a SCATS signal crossing based on video detection. Based on the video detector and big data analysis technology, the present invention realizes the acquisition of the queuing lengths of each entrance road and each lane of the SCATS signal intersection, which can not only be used for the optimization of the intersection signal scheme, but also be used for signal evaluation.

Description

technical field [0001] The invention relates to a method for constructing a queuing length model at a SCATS signal crossing based on video detection. Background technique [0002] At present, major cities have established their own intelligent traffic control systems. For example, Shanghai has adopted the Sydney Coordinated Adaptive Traffic System (SCATS for short, or SCATS system) in the city to carry out signal intelligent control of urban roads. The system uses a coil buried behind the stop line to detect vehicles, so as to obtain parameters such as flow rate and saturation (saturation in the non-traffic engineering sense). Although the system can realize functions such as single-point control and regional control, its signal control strategy is also controversial because its operating mechanism adopts the "equal saturation principle" and the saturation is not in the sense of traffic engineering. . [0003] Signal-controlled intersection vehicle queuing is very importan...
