This dataset contains information on median travel time and median driving speed between stations categorized by vehicle type. The data is collected and provided by the Traffic Data Collection Support System (TDCS). Two types of reports are aggregated in this dataset: M04A and M05A.

 Some north gates before 4/25 might be broken so the data is missing.

M04A Report:

• Report Code: M04A
• Time Interval: 5 minutes
• Data Delivery Period: Every 5 minutes
• File Format: .csv
• Directory: http://tisvcloud.freeway.gov.tw/history/TDCS/M04A/YYYYMMDD/hh
• File Name Format: TDCS_M04A_YYYYMMDD_hhmmss.csv
• Contents:
  • TimeInterval: Production time of the report in the format YYYY-MM-DD HH:MM:SS
  • GantryFrom: Upstream detection station number
  • GantryTo: Downstream detection station number
  • VehicleType: Type of vehicle (31: Small car, 32: Small truck, 41: Large car, 42: Large truck, 5: Articulated vehicle)
  • TravelTime: Median travel time between adjacent upstream and downstream detection stations in seconds
  • TrafficVolume: Total traffic volume passing through the upstream and downstream detection stations within the time range of the report

M05A Report:

• Report Code: M05A
• Time Interval: 5 minutes
• Data Delivery Period: Every 5 minutes
• File Format: .csv
• Directory: http://tisvcloud.freeway.gov.tw/history/TDCS/M05A/YYYYMMDD/hh
• File Name Format: TDCS_M05A_YYYYMMDD_hhmmss.csv
• Contents:
  • TimeInterval: Production time of the report in the format YYYY-MM-DD HH:MM:SS
  • GantryFrom: Upstream detection station number
  • GantryTo: Downstream detection station number
  • VehicleType: Type of vehicle (31: Small car, 32: Small truck, 41: Large car, 42: Large truck, 5: Articulated vehicle)
  • SpaceMeanSpeed: Median driving speed between adjacent upstream and downstream detection stations in km/hr
  • TrafficVolume: Total traffic volume passing through the upstream and downstream detection stations within the time range of the report

This dataset provides valuable insights into median travel time and driving speed for different types of vehicles between various detection stations, aiding in traffic analysis and management.
