Optimization Model and Practice of Coordinated Departure Interval of Common Line Bus Lines
Aiming at the problem of high repetition rate of bus lines,considering the existence of col-linearity in multiple bus lines,the departure interval of collinear bus lines was coordinated and opti-mized,which reduced the weighted cost of passengers and enterprises.An optimization model of coor-dinated departure interval with the goal of minimizing the weighted sum of passenger travel time cost and bus operation cost was constructed.The weights were calculated by entropy method,and the op-timal solution was calculated by GeoGebra graphic calculator.The example shows that the total cost savings in peak hours is 268.85 yuan,accounting for 4.18％of the actual operating cost.On the basis of saving the waiting cost of passengers,the attraction of public transport and the operating efficiency of public transport enterprises are improved,and the satisfaction of passengers is improved.
