虽然许多经典交通模型将街道的空间扩展连续或离散为一定长度的delta单元，但我们将道路细分为相对较长的均匀路段，这些路段具有恒定的容量，最后具有非均匀性。所建立的模型简单、高效。它受到动态排队网络模型的启发，并考虑了交通流的基本特征。它不是处理单个车辆或速度曲线，而是关注特定横截面的流量和车辆的平均行驶时间。
While many classical traffic models treat the spatial extension of streets continuously or by discretization into cells of a certain length Deltax, we will subdivide roads into comparatively long homogeneous road sections of constant capacity with an inhomogeneity at the end. The related model is simple and numerically efficient. It is inspired by models of dynamic queueing networks and takes into account essential features of traffic flows. Instead of treating single vehicles or velocity profiles, it focusses on flows at specific cross sections and average travel times of vehicles.
