为了提高低温环境下赛区内行人的出行效率、降低行人出行安全风险，首先从信息干预的角度，通过建立路网VMS信息发布与客流拥挤状态间的互动反馈机制以及路网VMS信息发布布局动态优化模型，提出了一种基于客流实时响应的路网VMS（可变信息板）自适应信息发布策略；然后，针对该策略，提出了基于多智能体的场景仿真方法；最后，以某寒冷赛事赛区为例，对有无VMS信息发布策略下行人入场、散场场景进行仿真。结果表明，与无VMS信息发布策略下的行人出行相比，在该策略下短时出行客流占比有所增加，入场阶段个人平均行走时间节省约2.6%，道路最大拥挤度降低约20.45%；散场阶段个人平均行走时间节省约7.0%，道路最大拥挤度降低约10.51%。该研究可为赛区管理者调控客流、提高观赛体验等提供理论基础和数据支撑。

This study proposed an adaptive information release strategy of VMS（variable message signs）in road network based on the real-time response of the passenger flow，in order to improve the travel efficiency and reduce the safety risk of pedestrians in the competition area under low temperature environment.First of all，from the perspective of information intervention，the dynamic feedback mechanism between the VMS information release and the crowded state of the passenger flow was established，and the dynamic optimization model of the VMS information release layout was formulated.The in response to the strategy，a scene simulation method based on multi-agents was proposed.A cold competition area was taken as an example to simulate the ingress and egress scenes with and without the VMS information release strategy.The results show that the proportion of short-term passenger flow increases，compared with that without the VMS information release strategy.For the ingress scene，the ave-rage walking time of pedestrians can be reduced by about 2.6%，and the maximum road congestion can be reduced by about 20.45%；while for the egress scene，the average walking time of pedestrians can be reduced by about 7.0%，and the maximum road congestion can be reduced by about 10.51%.The research can provide theoretical foundation and data support for the competition area managers to control passenger flow and improve the experience of spectating experience.
