Geopath Streetlytics Data Specification
Data Item: Â Â Â Â Volume and Speeds
Format: CSV
Structure: Delivered as a set of 88 CSV files segmented by region (22) and day type (4). Each file will include a header row. Any supplemental data or data patch will be delivered in the same naming convention with a suffix to indicate the specific patch or supplement. For each street segment, 288 records segmented by day type (4), hour (24) and motivation (3) will be provided.
Coverage: The data item will cover the Continental United States plus Hawaii and Puerto Rico except Alaska
Description: Volume and speed represent averages for the specified time period are provided on every directional street segment nationwide with a speed limit of 25 MPH or greater and all pedestrian permitted segments.
The confidence value should always be between 0 and 1.
The segment pedestrian volume should always be populated with one of the following:
A positive value represents the pedestrian volume on the roadway segment during the day type, hour and motivation.
A value of 0 represents no pedestrian traffic during the day type, hour, motivation.
A value of -1 represents that no pedestrian traffic is allowed on that road segment
