Data Collection & Maintenance

Collecting accurate data is vital to the work that PART does. Data used by PART comes from federal, state, or local agencies such as the U.S. Census Bureau, the U.S. Department of Transportation, the North Carolina Department of Transportation, and various local municipalities. Ridership data generated through Automatic Passenger Counters (APCs) located on all PART’s buses is reviewed, aggregated, and always kept up-to-date. A weekly diagnostic report guarantees that the devices are functioning properly. The APC data is often supplied to departments within PART, who use it to make critical decisions.

Other information often shared across agencies is route and bus stop data within the General Transit Feed Specification (GTFS). Therefore, ensuring that the GTFS is updated whenever a service changes is essential when sharing data. The data at PART is constantly being updated and archived for future reference and regulatory compliance.


Route Planning and Evaluation involves synthesizing existing operational data, industry best practices, and demographic and employment data. PART uses several tools to process, analyze, and visualize data. The Planning Department uses:

  • Longitudinal Employer-Household Dynamics (LEHD) data through an online tool called On The Map (See image below)
  • Catchment Area Analyses using Socio-Economic Data from the Regional Travel Demand Model
  • The Cost of Housing and Transportation Data, a measure of the overall cost of housing and transportation cost by families by location
  • Transit Propensity, a measure of ridership and transit service support based on population and employment
  • Remix, a route analysis tool that calculates route cost, length, hours, and service demographics automatically
  • Route ridership projections and potential from TBEST
  • Automatic Passenger Counter data that counts persons getting on and off a bus at each stop
