Traffic signal fast mode method

The invention relates to a traffic signal rapid mode method, which comprises the following steps of: 1) acquiring an instruction signal mode; 2) rapidly calculating and configuring a mode transition period from a current signal mode to the instruction signal mode; and 3) running a completion mode transition period before each intersection executes a new period. According to the method, the signal mode classification and mode source point positioning algorithm in the transition period calculation step in the real-time mode method is simplified, and the calculation time is reduced by more than 10%; meanwhile, all the advantages of a real-time mode technology, including the advantages of zero-time redundancy waiting and seamless smooth switching, are kept, the paradox of'congestion caused by smooth response 'is solved, and the redundancy waiting can be reduced by more than 50% even if the mode switching is carried out by taking a time difference period remainder as waiting, so that the traffic flow accumulation
