Abstract

The present application discloses a traffic flow model evaluation method, system, equipment and medium. The method includes: obtaining the basic data of the actual traffic flow for the road network of the target area, and the basic data of the actual traffic flow is arranged in the Collected in real time by multiple acquisition devices in the road network of the target area; data fusion processing is performed on the basic data of the actual traffic flow to obtain real traffic flow data including attribute labels; data conversion processing is performed on the basic data of the simulated traffic flow to obtain Simulated traffic flow data; based on real traffic flow data and evaluation attribute labels, simulate and evaluate simulated traffic flow data. Therefore, the simulation effect of the traffic flow model involved in the autonomous driving technology can be accurately evaluated, and the authenticity and correctness of the traffic flow model can be evaluated from multiple dimensions.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to an evaluation method, system, device and medium of a traffic flow model. Background technique [0002] With the gradual rise of autonomous driving technology and the gradual popularization of smart cities, traffic simulation technology is becoming increasingly important. The traffic flow simulation technology is to complete the simulation of the actual road traffic state in the computer simulation environment, so as to predict the traffic flow according to the simulation results. [0003] In the future, self-driving vehicles and human-driving vehicles of various manufacturers will drive in various complex traffic scenarios. The design and planning of smart cities also need a traffic flow simulation model that is infinitely close to reality to predict urban traffic conditions. The traffic flow simulation system should be used And born. [0004] However, how to effect...
