Abstract

Embodiments of the invention provide a traffic simulation method and a traffic simulation system based on floating car data, and relate to the field of intelligent transportation. The method comprises the following steps: acquiring floating car data and urban road network data; performing road congestion evaluation based on the floating car data and the urban road network data to acquire the road information of a congestion area, wherein the floating car data includes floating car speed information and GPS positioning information; editing an original congestion area road network based on the road information of the congestion area to generate an edited road network topology; and performing traffic equilibrium assignment on the edited road network topology.

Description

technical field [0001] The embodiments of the present invention relate to the field of intelligent transportation, in particular to a traffic simulation method and system based on floating car data. Background technique [0002] Floating car technology is one of the advanced technical means used in the international intelligent transportation system to obtain road traffic information in recent years. According to the vehicle position, direction and speed information regularly recorded by the floating vehicle equipped with the vehicle-mounted global positioning system during its driving process, the relevant calculation models and algorithms such as map matching and path estimation are used for processing, so that the floating vehicle position data and urban roads Time and space are correlated, and traffic congestion information such as the vehicle speed of the road that the floating car passes and the travel time of the road are finally obtained. [0003] The road traffic e...
