Non-signalized intersection lateral traffic volume prediction device and method

Abstract

The invention discloses a non-signalized intersection lateral traffic volume prediction device and method. The prediction device comprises an intersection traffic volume information collecting module which communicates with a lateral traffic volume computation module, and the lateral traffic volume computation module communicates with a prediction information release module; the intersection traffic volume information collecting module transmits quantity information to the lateral traffic volume computation module, the lateral traffic volume computation module predicts the quantity of the traffic volume obtained when traffic participants pass the intersection through a Poisson distribution formula according to the traffic volume information collected by the intersection traffic volume information collecting module, and the predicted traffic volume information is released in a prediction information release module. The prediction device and method predict lateral motor vehicles, non-motor vehicles and pedestrians, are especially suitable for controlling intersections in a non-signalized mode and are used for predicting the intersection lateral traffic volume information, safety is increased, and the traffic capacity is improved.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a device and method for predicting lateral traffic volume at an unsignalized intersection. Background technique [0002] With the rapid advancement of my country's urbanization and the further expansion of the highway system, it is inevitable that there will be a considerable number of level intersections without signal management and control in the process of highway construction. Due to the small traffic volume of these intersections, some drivers often drive fast, which is easy to cause accidents under the condition of incomplete information; at the same time, because they are intersections, some drivers drive cautiously and drive slowly, which often leads to a decrease in traffic capacity. [0003] In response to this problem, a search of existing patents found that the patent application number "201610032796" "a method for judging the probability of motor ...

Problems solved by technology

[0006] (2) Due to the influence of traffic participants by the information released by the display screen, the time it takes for them to arrive at the stop line at the intersection after receiving the information on the display screen and other factors, the sensing distance of lateral traffic volume should be a dynamic problem
