The invention discloses a traffic flow dynamic collaborative distribution method under a distributed framework. A plurality of virtual local sub-planning centers are set up by taking an intersection as a secondary distribution unit, and each sub-planning center manages a plurality of road sections connected with the intersection. Each sub-planning center re-plans a passing path for the vehicle in the local area according to a specific rule and selects a next passing road section. The flow distribution processes of a plurality of sub-planning centers can be synchronously carried out, and finally the flow distribution result is fed back to the previous level, so that the traffic flow distribution efficiency is greatly improved; meanwhile, the traffic flow is distributed to the road section by means of a bidding mechanism in market behaviors, and the traffic flow dynamic collaborative distribution method for the urban road network is provided. According to the method, firstly, congested road section intersections are analyzed and screened on the basis of road section impedance analysis, in each congested road section intelligent agent, the congested road sections serve as tenderees, unblocked road sections serve as tenderers, and vehicles are distributed to the bidding road section with the highest bid by adopting a bidding mechanism.
本发明公开了一种分布式框架下交通流动态协同分配方法,以交叉路口为次级分配单位设立了多个虚拟的局部子规划中心,每个子规划中心管理与此交叉路口连接的多个路段。每个子规划中心根据特定规则在此局域内为车辆重新规划通行路径并选择下一通行路段。多个子规划中心的配流过程可以同步进行,并最终将配流结果反馈到上一层次,大幅提升了交通配流效率;同时借助于市场行为中的招投标机制向路段分配交通流,提出了面向城市路网的交通流动态协同分配方法。该方法首先在对路段阻抗分析的基础上分析并筛选拥堵路段交叉口,在每一个拥堵交叉口智能体中将拥堵路段作为招标人,将畅通路段作为投标人,采用招投标机制将车辆分配给出价最高的投标路段。
