- Abstract
- The urban traffic simulation is one of solutions to analyze and forecast the traffic state for city road network. In order to simulate the real traffic situation well, the fine-tuning simulation inputs, including road network and traffic demands, closer to real measured data is important. In this paper, we present the UNIQ-SALT, which is the urban mesoscopic traffic simulation, and its calibration process to fit the simulated results to real traffic data collected by diverse spots in target area including about 100 traffic signals on Yooseong area, Daejeon. Finally, compared with measured real traffic volume and passing speed, we show the simulated result is within about 10% errors coverage.
