高速公路车流量统计信息（可定制）

高速公路服务区驶入流量、高速公路旁现有广告牌车流量和收费站区分车型的车流量统计数据，每日生成前一天数据，可通过接口按需调取。

This dataset includes three categories of traffic statistical data: inbound traffic volume at expressway service areas, vehicle traffic volume passing existing billboards alongside expressways, and vehicle traffic volume at toll stations categorized by vehicle type. It is generated daily using the data of the previous day, and can be retrieved on demand via application programming interfaces (APIs).
