The invention discloses a
bus rapid transit signal priority timing method under
trunk line coordination control. The
bus rapid transit signal priority timing method under the
trunk line coordination control comprises the following steps that: 1, an annunciator judges whether a
bus application is detected by a
bus rapid transit vehicle detector, forecasts a moment t1 when a
bus rapid transit vehicle reaches a stop line if the
bus rapid transit vehicle detector detects the bus application, and otherwise, ends the judgment at the current moment; 2, if the bus
rapid transit vehicle detector detects the bus application during phase
green light coordination and the bus rapid transit vehicle reaches the stop line at an intersection during the phase
green light coordination, the annunciator keepsthe original
signal timing constant, and otherwise, performs
green light prolonging control; and 3, if the bus rapid transit vehicle
detector detects the bus application during phase
red light coordination and the bus rapid transit vehicle reaches the stop line at an intersection during the phase green light coordination, the annunciator keeps the original
signal timing constant and otherwise, performs green light in-advance turning-on control.
