摘　　要：针对公交线路重复率过高问题,考虑多条公交线路中存在共线情况,将共线公交线路的发车间隔进行协调优化,减少了乘客和企业的加权成本和。构建了以乘客出行时间成本、公交运营成本加权和最小为目标的协调发车间隔优化模型,并采用熵值法计算权重,运用GeoGebra图形计算器计算最优解。结果表明:高峰小时节约成本共计268.85元,节约成本占实际运行成本的4.18%.在节约乘客候车成本的基础上,提高公交吸引量,提升乘客出行满意度,提高公交企业营运效率.Aiming at the problem of high repetition rate of bus lines,considering the existence of collinearity in multiple bus lines,the departure interval of collinear bus lines was coordinated and optimized,which reduced the weighted cost of passengers and enterprises.An optimization model of coordinated 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 optimal 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.
