Abstract

The invention discloses a method and a device for adjusting parameters of a simulation model, and relates to the technical field of transportation simulation. The method includes determining a value of at least one parameter according to the acquired at least one parameter and a value range thereof; running a simulation program corresponding to the simulation model according to the parameters and the values thereof, and acquiring a simulation result including simulation data; calculating a similarity value of the simulation data and real data according to the simulation data in the simulation result and the real data; when the similarity value is larger than or equal to a preset threshold, determining a simulation model target parameter set as a first parameter and a value corresponding to the first parameter. The method and the device are suitable for regulating the parameters of the simulation model, the parameters of the simulation model can be adjusted adaptively, time for acquiring reasonable parameters of the simulation model is short, and efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of traffic simulation, in particular to a method and device for adjusting parameters of a simulation model. Background technique [0002] The simulation model refers to decomposing all concerned tactical phenomena into a series of basic activities and events, and combining them according to the logical relationship between activities and events. The simulation model is the analogue of the simulated object or its structural form. The traffic simulation model realizes the simulation of current or predicted future traffic conditions through software programs. Due to differences in driver behavior, vehicle attributes, and signal light control logic in different countries, different regions, or different cities, the traffic model applicable in one area cannot simulate local traffic conditions well in another area, so it needs to be based on the local traffic model. Carry out the necessary parameter adjustment o...
