基于RTI的交通态势实时仿真技术研究

微观交通仿真系统一般主要是以历史调查数据的统计分析结果为依据进行仿真,为了能够更加真实地反映交通的状况,提出了以实时采集的交通数据和历史交通数据的OD反推技术为基础,通过微观仿真的形式,结合分布式仿真技术和虚拟现实技术,离线或者在线地再现路网的真实交通情况,为管理者提供直观的决策依据。

Study on Real-time Simulation Technology of Traffic Situation Based on RTI

Generally, micro traffic simulation system is simulated based on statistics of historical investigation data. In order to reflect the traffic situation much better, the real time gathering traffic data and historical traffic data were taken with OD matrix estimation technology as a base, and the micro simulation form was used together with distributed simulation technology and virtual reality technology to reproduce on-line or off-line real traffic situation of road network, which provided intuitive strategy basis for management.
