基于关键客流密度选择支路公交运营模式的方法

Methodology for Selecting Feeder Bus Transit Mode Based on Critical Passenger Flow Density

公交支线采用灵活式运营模式,可以通过接驳点将所服务区与交通网连接起来,为乘客提供更有效快捷的运行方式。但在实际的设计和运营过程中,往往很难选择运用何种模式更合适。鉴于此,提出公交运营模式选择模型以协助决策者做出更合理的选择。采用连续近似方法估算关键需求密度,通过分析单车辆和双车辆情况下的运营参数,比较模拟生成的值,验证分析建模方法的有效性。

Flexible transit services of feeder transit connect a service area to a major transit network through a transfer point to provide passengers with a more efficient and effective operation. In designing and running such systems, however, the selection of transit mode is often hard. In this paper, it proposes an analytical model and solution of the problem to assist decision makers and operators in their choice. By employing continuous approxi- mation method, it estimates the critical demand densities. Based on the results of one-vehicle and two-vehicle operations for various scenarios, in comparison to values generated from simulation, the validity of analytical rood-eling approach is verified.
