为提高线网规划精度与效率,构建了基于点-域匹配的线网规划方法,从区位与客流匹配角度出发,确定了线路合理搜索范围的边界域方程及公交线路优化模型,并采用从左算法实现了合理搜索域内有效线路的穷举,通过多目标决策实现了优化模型的求解。计算结果表明:采用线网规划方法所得线网与实际规划结果基本一致,此外,由于设定了线路的关键性控制点及有效走行域,简化了线路搜索过程,提升了模型运算效率与精度,方法具有实用性。
In order to improve the planning accuracy and efficiency of line network, this paper constructs a line network planning method based on point-domain matching. Based on the matching of location and passenger flow, the boundary domain equation and bus line optimization model of line reasonable search range are determined. The algorithm realizes the exhaustive search of effective routes in the domain, and realizes the optimization model through multi-objective decision-making. The calculation results show that the network obtained by the method of line network planning is basically the same as the actual planning result. In addition, the key control points and the effective running area of the line are set, which simplifies the line search process and improves the efficiency and accuracy of the model operation. The method is practical.
