快速公交(BRT)线路布设优化算法研究

Optimization Algorithm of Bus Rapid Transit Route Planning

快速公交(BRT)在我国方兴未艾,而目前缺乏实用的快速公交线网布局优化方法。针对传统直达客流方法应用于快速公交线网布局优化的不足,根据快速公交的特点和功能定位,提出了以直达客流运输密度最大和直达客流绕行系数最小为目标的快速公交线网布局双层非线性优化模型,对模型合理性进行了论证,并提出了简单容易操作的实用求解算法。

Bus Rapid Transit is blossoming in our country, but there is rare research on the method of Bus Rapid Transit route planning, aim at the shortcoming of general method of bus route planning, this paper puts forward a new model of doubledeck. A optimization algorithm has been improved and applied to the Bus Rapid Transit network optimization, the model and algorithm prove feasible and practical in practice.
