公交线路资源配置与高峰客流协调评价研究

公交线路资源配置与高峰客流协调发展是公交系统可持续发展的重要保障.对二者协调程度进行评价,通过对公交系统规划与运营的深入研究,运用数据包络分析法,以公交车辆数、站点数、沿线客流强度为投入指标,以高峰客流量、高峰满载率适宜度为产出指标组成评价指标体系,并建立二者之间协调评价模型.以哈尔滨市主城区86条公交线路为评价单元,利用数据包络分析法的CCR模型,得到了每条线路的相对效率值,对每条线路进行协调度评价.结果表明,40条处于强协调状态、34条处于弱协调状态、9条处于轻度失调状态、3条处于严重失调状态,公交线路总体上处于弱协调状态.提出的评价方法在实际运营中具有较强的实用性,可为公交规划与运营管理提供理论依据.

Evaluation of Coordination between Bus Lines Resource Allocation and Peak Passenger Flow

The coordinated development between bus lines resource allocation and peak passenger flow is an important guarantee for sustainable development of the public transport system. To evaluate the coordination degree of the relationship between the two objects, through in-depth study of the planning and operation of bus system, uses DEA(data envelopment analysis), the evaluation model is established, which put bus vehicle number, station number and passenger flow strength along the bus line as input indicators, and put the peak passenger flow and peak load ratio suitability as output indicators. Taking 86 bus lines in the urban area of Harbin city as the decision making units, by using CCR model from DEA, gets the relative efficiency value of each line, and gives the coordination degree for each line. The result shows that 40 lines are under strong coordination, 34 lines are under inferior coordination, 9 lines are under mild imbalance, and 3 lines are under critical imbalance, the whole bus system is generally at inferior coordination level. The proposed evaluation method is practical in actual operation, can provide the theoretical basis for planning and management of public transport.
