(2) main signal phase
Traffic events [the TE being had an impact for the green time management of current green light main signal phasemain(no.)] include:
TEmain(1): the green time of current green light main signal phase reaches minimum green time；
TEmain(2): the green time of current green light main signal phase reaches maximum green time；
TEmain(3): all pre-signal phases of current green light main signal phase upstream show amber light or red light；
TEmain(4): current green light main signal phase without vehicle continuously close to main signal stop line, i.e., each of belonging to the phase into
The time headway of most proximal end detectors acquisition in mouthful direction is successively greater than that such detector confirmation vehicle is continuously current to be needed
The time headway threshold value asked；
TEmain(5): the synthesis in each import direction belonging to current green light main signal phase has emptied vehicle to row area, i.e. the phase
The time headway of all remote sensors acquisition in each import direction belonging to position is simultaneously greater than such detector confirmation synthesis
It is true that such detector is simultaneously greater than to the time headway that row area empties the time headway threshold value of vehicle, all proximal end detectors acquire
Recognize the comprehensive time headway threshold value that vehicle is emptied to row area；
