本文对高峰时段的城市公交线路进行了数学描述。“公交路线”在这里被用来表示一组或多或少并行的子路由，在这里被称为“服务变体”。分析了公交运营的确定性和随机性机理，重点分析了公交运营的时间演化，建立了公交线路结构、上下车事件、路段行程时间和停车时间的一般模型。为了验证和模型选择，定义了各种拟合优度的度量。这些模型主要用于交互式模拟程序(见Anderssonet al.，1979)。
The present paper is a mathematical description of an urban bus route in peak hour traffic. “Bus route” is here used in a collective sense to denote a set of more or less parallel-going sub-routes, here called “service variants”. The deterministic and stochastic mechanisms of bus operation are analysed—with focus on time evolution—and general models for route structure, boarding and alighting events, link travel times and stop times are formulated. Various measures of goodness of fit are defined, for validation and model choice. The models are primarily intended for use in an interactive simulation program (see Anderssonet al., 1979).
