点－域匹配的公交主干线网规划方法

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。

Planning method of bus main artery network based on point-area match

In order to improve the accuracy and efficiency of bus network planning,a planning method was proposed based on point-area match theory,the boundary area equation of sensible searching range was determined,and the optimization model of bus lines was set up based on considering the match between area location and passenger flow. A "from left" algorithm was applied to get the enumeration of effective bus lines within sensible searching area,the optimal line was gained by using multi-objective decision,finally the new planning method was tested with an example. Analysis result shows that the line network scheme obtained by new planning method is consistent with the real line network scheme,the accuracy and efficiency are greatly improved because the searching process is greatly simplified by giving the key controlling point and effective area,so the method has practicability. 9 figs,13 refs.
