Bus Signal Priority Control Model under Bus Lane

Abstract

In order to avoid or reduce the phenomenon of train running in urban public transport, it is considered that when there is a large headway, the control measures of bus speed guidance and bus signal priority should be taken in time to reduce the delay caused by bus stopping and waiting when passing the intersection. Taking the headway of the upstream station of the intersection as the decision index. When the headway greater than 1.5 times of the initial departure interval, implementing the control model. Taking the minimum delay of intersection as the objective, taking the optimization phase and the saturation of influence phase as the constraint conditions, taking the green light adjustment time and cycle length as variables, and considering the change of the travel time due to the speed adjustment to the intersection, a linear programming model of bus signal priority is established. The results show that under the condition of high and low saturation, the headway decreases by 10.3% and 8.0% when the green light is extended, by 0.5% when the red light is cut off early, by 6.1s and 7.0s when the vehicles pass through the intersection, and by 3.1% and 2.7% when the passengers wait for the next station.
