Improved information feedback in symmetric dualchannel traffic

Abstract

Information feedback is very important in traffic systems. Real-time information feedback can improve traffic flow with existing facilities. This paper proposes a real-time information feedback strategy named improved mean number feedback strategy. Based on a two-route scenario, simulation results show that the strategy is much more effective in different length of roads or in different percentage of dynamic vehicles than the old strategies, i.e., congestion coefficient feedback strategy and mean velocity feedback strategy.
