动态交通仿真理论应用与发展——“交通7+1论坛”第三十四次会议纪实

The Application and Development of Dynamic Traffic Simulation Theory

交通仿真是一种应用计算机数字模型技术来反映复杂交通现象的交通分析方法.交通仿真是计算机仿真技术在交通工程领域的一个重要应用,已经成为交通研究、规划和管理人员的重要工具,被广泛应用于道路规划评价,交通组织和交通管理优化,交叉口渠化和优化配时设计等等,使交通管理从定性走向定量、从经验走向科学.随着交通带来的效率、环境、能源和安全问题的进一步加剧,随着物联网与大数据时代的到来,为交通仿真的高速发展带来了机遇,交通仿真也从传统的离线走向在线.

Traffic simulation,based on applied computer digital model,is an analysis method for complex traffic phenomenon,which has been an important application of computer simulation technology in traffic engineering.Researchers,designers and managers utilize the simulation widely to evaluate traffic planning,organization and management,and optimize intersection channelization and signal timing.This method pushed the research on traffic management from qualitative to quantitative,from empirical to scientific.The time of the Internet of Things and big data provides opportunities for traffic simulation to deal with the increasing problems of efficiency,environment,energy and safety caused by traffic,and improves traffic simulation from off-line mode to on-line mode.
