Abstract

The present invention discloses a method and device for realizing traffic flow prediction and a readable storage medium. The method comprises a step of acquiring flow data of an intersection coil anda check point associated with an area and floating vehicle trajectory data, a step of obtaining an inflow base and an outflow base of traffic flow in the area according to the flow data and the floating vehicle trajectory data, a step of acquiring tensors describing historical traffic flow in the region according to the a proximity time characteristic, a periodic time characteristic and a trendingtime characteristic, a step of fusing and outputting a tension prediction initial value of the area in a next time interval through the operation of a proximity depth residual network, a periodic deep residual network and a trending depth residual network, and a step of obtaining a tension prediction value of the area in the next time interval according to the tension prediction initial value ofthe area in a next time interval. Thus a technical problem that the accuracy of predicted traffic flow is not high due to the influence of the time characteristic is solved.

Description

technical field [0001] The invention relates to the field of traffic control and management, in particular to a method and device for realizing traffic flow prediction, and a readable storage medium. Background technique [0002] With the rapid development of urban traffic, the prediction of traffic flow is crucial to traffic management and public safety. In the existing methods for realizing traffic flow forecasting, the traffic flow forecast of a certain time interval in the future is realized by obtaining and analyzing the flow data of historical traffic flow, so as to start the early warning mechanism in advance, to ease the crowd and traffic flow as soon as possible, and to ensure the traffic flow within the area. The short-term traffic flow and population density are within the safe range, thereby preventing the occurrence of major traffic accidents and catastrophic urban safety incidents (such as stampede incidents). [0003] As can be seen from the above method, in ...
