The application discloses a kind of
bus trunk multi-intersection conditional
signal priority control method, first, determine optimization target, i.e. improve the
punctuality performance of BRT
system and minimize the adverse effects on private car;Second, establish conditional TSP model, the
delay constraint of vehicle, traffic priority time constraint and saturation and
queue length constraint, ensure that vehicle arrives on time, balance the relationship between
bus punctuality and private car
delay;Third, collect the motor vehicle flow demand of
station and
station section intersection, intersection
signal timing, upstream
bus station departure time and downstream bus station
arrival time data;Finally, the model is solved using mixed integer nonlinear
programming method.The application solves the problem of unexpected
arrival time of bus vehicles at continuous intersection stop lines affecting the reliability of the operation of the
bus rapid transit system, improves the
punctuality performance of the
bus rapid transit system, minimizes the adverse effects on private cars, and improves the
overall efficiency of the transportation system.
