Improved information feedback in symmetric dual-channel traffic

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