Abstract:Aimed at the congestion evacuating,an available self-organizing signal control principle whithout signal cycle and fixed phase as well as phase order is proposed.The designed signal control method is based on inductive loop data to identify the congestion flow and will overcome the deficiency of the present signal control mode for controlling congested traffic flow.For maximizing the number of passing vehicles,the proposed signal control method includes some key components such as setting stand-by phases,weighting each stream,deciding the maximum waiting time and allocating signal timing.The method is tested and compared through simulation with VISSIM.The comparative analysis shows that the proposed method can evacuate the congested traffic flow of a congested intersection more effectively.
