ITRE manages the North Carolina Non-Motorized Volume Data Program (NC NMVDP) for the North Carolina Department of Transportation (NCDOT). The NC NMVDP began as a research project to test a bicycle and pedestrian count protocol for replication across the state. The program currently includes one of the most extensive statewide networks of continuous bicycle and pedestrian counting sensors and provides data management and reporting support for multiple local agency partners. The bicycle and pedestrian counting systems are installed on sidewalks, roadways, and shared use paths across the state. The data produced from this program can be used to evaluate facility usage over time, inform the project prioritization process, provide quantifiable evidence to support multi-modal Complete Streets policies, and improve municipal and regional active transportation planning. The data can be used in planning tools to measure existing patterns and model future trends at the site, corridor, and regional levels.

In late 2018, the NC NMVDP was restructured from a linear set of research tasks into a formal program structure based on three coordination areas (Local Agency, Equipment, and Data) encompassed by overall project management. Under this structure, each coordination area is assigned a technical lead for oversight of its discrete day-to-day tasks.


Annual Data Reports: 2015-2019

Annual data are provided for counters that have been in place for a full program year (December through November) and that have had their accuracy assessed through a validation study. Based on the application of quality control, quality assurance, and validation procedures, invalid data have been removed from the dataset and correction factors have been applied. Documentation of data issues and their descriptions that led to the removal of data at specific counting locations are included for reference here.

Annual data are screenline counts by mode for each counting location. Annual data are reported through vendor-provided software, Eco-Visio 5, using a dashboard system. All available historic annual data for a given counter by mode are provided.

Disclaimer for Annual Data Use:
The annual data stored and accessed in Eco-Visio 5 are verified and validated. These data have been subjected to the NC NMVDP’s quality control, quality assurance, and validation procedures and meet the criteria and standards of official NC NMVDP data. Invalid data resulting from equipment malfunction or other sources of error have been removed and site-specific correction factors have been applied to adjust for undercounting or overcounting that may have occurred at a site. These data can be used for official reporting purposes.

To access the dashboards, please follow these steps:

Step 1:

Username: NMVDP_AnnualData
Password: Public

Step 2a:
Click Eco-Visio: Discover the new dashboards to access the Eco-Visio dashboards landing page.

Step 2b:
If the Eco-Visio counter management landing page is reached instead, click Click here to go to the newest version of Eco-Visio to access the Eco-Visio dashboards landing page.

Step 3:
Click Sites Dashboards to access the dashboards for each counting location by mode included in the annual data reporting.

Step 4a:
Select Sort by… Name located in the upper left corner of the screen beneath the 86 Sites title to sort the sites alphabetically. 

Step 4b:
Select Filter Sites located in the upper left corner of the screen beneath the 86 Sites title to filter the sites by municipality and mode. 

Step 5:
Click a counting location by mode from the left menu bar to display its annual data report. All available historic annual data for a given counter by mode are provided.


Program History

2014-2015: Phase I, Pilot

The pilot phase of the NC Non-Motorized Volume Data Program was conducted in NCDOT Divisions 7 and 9 (the Piedmont Triad region) to test a bicycle and pedestrian count protocol and replicate the methodology across the state. Twelve continuous count stations began monitoring bicyclist and pedestrian travel in late 2014. These stations cover a mix of sites across different land uses, travel patterns, and volume groups. Detailed technical information can be found in the Phase I Final Report and Appendices. The following programmatic elements were piloted:

  • Agency Coordination
  • Site Selection and Procurement
  • Equipment Installation and Onboarding
  • Equipment Validation
  • Data Handling, Monitoring and Management
  • Equipment Maintenance
  • Data Reporting


2015-2016: Phase II, Expansion

Phase II of the project started in 2015 with expansion to NCDOT Divisions 4, 5, 8 and 10. Two additional shared use path sites in Brevard and Duck were installed in 2015 and continuous count stations were installed on roadways, sidewalks, and shared use path in Charlotte in 2016.


2016-2017: Phase II Continues

Phase II continued through 2017 with installations in NCDOT Divisions 4, 5, 8, and 10. Supplier issues resulted in lost data and the need to replace some systems. Stations where significant data were lost (greater than 90 days) are noted in the data report.


2017-2018: Phase II Continues, Data Reporting Updates Begin

Phase II installations in the CAMPO region were completed in Summer 2018. Efforts began to refine data handling processes including transitioning to a semi-automated system for data quality assurance & quality control and moving data reporting to an online dashboard system rather than spreadsheet files.

For the first time, annual datasets were provided through Eco-Visio 5 using its dashboard system. This system allows users to download tabular data, map counter locations, and analyze data using charts & graphs. This system allows users to access verified and validated data in a timely manner and in an accessible format. Historic annual datasets were transitioned to the Eco-Visio 5 system in early 2020 and made public with the release of the 2019 annual data report.

2018-2019: Program Evaluation Begins

In Spring 2019, ITRE began evaluating the NC NMVDP as the program entered its sixth year. This included gathering feedback from agency partners on all aspects of the program, including agency coordination & agreement execution; site selection, installation, & maintenance of the counters; and data processing, analysis, & reporting. Please stay tuned for more details as this effort concludes.
