本文建立了一个网格化道路网的连续模型，用于确定道路网的最优等级系统。等级系统表示为等级中每一级道路所占的面积比例。其目标是获得最佳的道路面积比，使总行程时间最小化。该模型明确地结合了向内，向外，通过交通以及内部交通来研究交通组成如何影响道路面积的最佳比例。研究结果表明，城市主干道的最优比例随着城市内、外、直通交通量的增加而增加。
This paper formulates a continuous model of a grid road network for determining the optimal hierarchical system of road networks. The hierarchical system is represented as the proportions of area taken up by roads at each level of the hierarchy. The objective is to derive the optimal ratio of road areas that minimizes the total travel time. The model explicitly incorporates inward, outward, and through traffic as well as inner traffic to examine how traffic composition affects the optimal ratio of road areas. The result reveals that the optimal ratio of major arterial roads increases with inward, outward and through traffic.
