一个扰动效用路径选择模型
A perturbed utility route choice model
摘要：
本文提出了一个路径选择模型，将出行者的行为表示为在流量守恒约束下的效用最大化网络流量分配问题。路由之间的替换取决于它们重叠的程度。{ \tr模型是考虑路线备选方案的完整集合来估计的，并且不需要生成选择集合。然而，估计只需要线性回归，并且非常快。该模型的预测可以使用凸优化计算，即使对于大型网络，计算也很简单。我们估计和验证模型使用一个大型数据集，包括1,337,096 GPS行程轨迹在大哥本哈根道路网络。
英文摘要：
We propose a route choice model in which traveler behavior is represented as a utility maximizing assignment of flow across an entire network under a flow conservation constraint}. Substitution between routes depends on how much they overlap. {\tr The model is estimated considering the full set of route alternatives, and no choice set generation is required. Nevertheless, estimation requires only linear regression and is very fast. Predictions from the model can be computed using convex optimization, and computation is straightforward even for large networks. We estimate and validate the model using a large dataset comprising 1,337,096 GPS traces of trips in the Greater Copenhagen road network.
