Results of the route choice experiments over the Lyon road network

The data contains the route choices of the participants in computer route choice experiments. The data is organized in long format, so there are three lines per choice, where each line corresponds to an alternative route. Six attributes of the alternative routes are included: Euclidean distance between origin and destination, the length of the route, the number of turns per km, the directness, the % of freeway composition and the travel time informed to the participants in the experiments.<br>本数据集收录了计算机路径选择实验中参与者的路径选择数据。该数据集采用长格式（long format）进行组织，每一组选择对应三条记录，每条记录对应一条备选路径。数据集包含备选路径的六项属性：起讫点间的欧氏距离（Euclidean distance）、路径实际长度、每公里转弯次数、路径直达性、高速公路占比，以及实验中向参与者告知的行程时间。
