Active Transportation Count Dataset
The Pedestrian and Bicycle Count Dataset documents non motorized traffic on state highways, originating from Caltrans district pilots initiated in 2023 to monitor active transportation. Data is vendor-collected using technologies like video analytics, then shared with HQ via APIs or files for statewide standardization in CSV format. Core variables include Loc_id (site identifier), Date/Hour (timestamp), Direction, Count (integer volumes), and geospatial (latitude/longitude). Limitations include potential undercounts in adverse weather and incomplete coverage. This supports equity-focused planning under Complete Streets policies, with updates as pilots expand.

License - Creative Commons 4.0 Attribution 3. Methodology - Data is collected through Caltrans district pilot projects on the state highway system, primarily using automated sensors such as video analytics to capture hourly pedestrian volumes at selected locations. Site selection prioritizes high-activity areas like urban intersections, with counts typically conducted continuously to establish baseline patterns. Vendors handle initial setup, calibration (e.g., adjusting for weather sensitivity), and raw data capture, transmitting files via APIs or secure shares to HQ. At HQ, data undergoes reformatting, aggregation, cleaning (e.g., removing duplicates or invalid entries), and standardization into CSV format, including validation for completeness in core fields like Date, Hour, and Count. For more detailed quality assurance, including error tracking and improvement strategies, refer to the associated DDP-10 Data Quality Management Plan.
