基于疾病传播理论的小区域节点协调控制算法

Coordination and Control Algorithm of Regional Essential Nodes Based on Disease Propagation Theory

为降低小区域路网整体调控策略制定难度,缓解区域交通拥堵问题。通过将疾病传播理论和复杂网络中的相关理论运用到道路网络中,构建管控策略预判模型,建立了交通路网中关键节点的监控算法。该算法只需在网络中监控部分关键节点就能够起到对整个路网监控的效果,从而针对关键节点的不同状态运用不同管控方案,有效改善区域交通拥堵状态。

In order to reduce the difficulty of overall regulation strategy about small regional road network and alleviate the problem of regional traffic congestion.The monitoring algorithms of key nodes in traffic network are established by applying the theory of disease propagation and related theory to the road network and the prediction model of control strategy is constructed.The algorithm only need to monitor some key nodes in the network but to achieve the whole road network monitoring,so as to use different control strategy for different states of key nodes.Therefore,it improves the regional traffic congestion effectively.
