收藏资源简介:
该数据集是法国公开数据的一部分,名为“拼车行程记录 - 拼车证明注册表”,旨在通过开放数据促进行政透明度。数据集包含法国拼车(covoiturage)行程的月度记录,这些记录来自拼车证明注册表(Registre de Preuve de Covoiturage),并经过处理以确保符合隐私保护要求。处理步骤包括:匿名化(删除司机和乘客标识符)、应用时间段(出发和到达时间四舍五入到10分钟)、地理网格化(根据密度将经纬度截断到2或3位小数,精度分别为约700米和70米)以及删除孤立地理网格的行程(如果出发或到达的INSEE代码出现次数少于6次)。数据集每月更新,但频率不固定,每个文件对应一个月的短途拼车行程。每条记录代表一个拼车行程,包括司机和乘客的信息,但注意数据集不覆盖法国所有拼车活动,也不能用于市场份额计算。数据字段包括行程ID、时间戳、地理位置(经纬度、INSEE代码、城镇等)、距离、持续时间、激励信息等,共28个字段,以Parquet或CSV格式提供。数据集强调隐私保护,约1.5%的行程因处理被过滤,具体统计信息见各月度文件描述。
This dataset is part of French open data, titled Trajets réalisés en covoiturage - Registre de Preuve de Covoiturage (Car-pooling trips - Car-pooling Proof Register), aimed at promoting administrative transparency through open data. It contains monthly records of car-pooling (covoiturage) trips in France from the Car-pooling Proof Register, processed to comply with privacy protection requirements. Processing steps include: anonymization (removal of driver and passenger identifiers), application of time slots (departure and arrival times rounded to 10 minutes), geographic gridding (latitude and longitude truncated to 2 or 3 decimal places depending on density, with accuracies of approximately 700m and 70m respectively), and removal of trips in isolated geographic grids (if INSEE codes for departure or arrival occur less than 6 times). The dataset is updated monthly, but the frequency is not fixed; each file corresponds to one month of short-distance car-pooling trips. Each record represents a car-pooling trip involving a driver and a passenger, but note that the dataset does not cover all car-pooling activities in France and cannot be used for market share calculations. Data fields include journey ID, timestamps, geographic locations (latitude, longitude, INSEE codes, towns, etc.), distance, duration, incentive information, etc., totaling 28 fields, provided in Parquet or CSV format. The dataset emphasizes privacy protection, with approximately 1.5% of trips filtered out due to processing; specific statistics are detailed in each monthly file description.
