COVERLAB staff provide decision planning services to help improve commercial vehicle enforcement effectiveness.

Decision Support Analysis

COVERLAB Analytics is a data visualization tool that helps supervisors plan their operations more effectively by:

  • Tracking each troop’s performance against CVSP goals
  • Visualizing relationships between enforcement, crashes, and poor condition roads and bridges
  • Identifying appropriate data-driven activities for improving commercial vehicle safety outcomes

Troop supervisors are provisioned with custom views to track, measure and prioritize enforcement activities to areas and times where safety and infrastructure protection needs are the greatest.


Data visualization helps troopers see crashes relative to enforcement activities. This provides intuitive intelligence for prioritizing locations, times, days, and types of enforcement activities needed for maximizing effectiveness.


Interactive maps show relationships of weight screening locations to poor condition road segments and bridges.

Operational Planning Support

COVERLAB staff help craft federal grant applications (CVSP Basic, High Priority, ITD, etc.), and help identify performance metrics that drive enforcement activities.

COVERLAB staff quantify the estimated lives saved, crashes avoided, and injuries prevented directly attributed to roadside enforcement activities. This translates to suggested personnel allocation optimized to improve the effectiveness of these activities.


COVERLAB staff assist troops with using local data to develop troop-specific enforcement plans. This approach allows each troop to develop its own unique intelligent strategies subsequently maximizing resource effectiveness.


We provide on-demand maps, data analysis, and field support for special enforcement operations.


COVERLAB staff deliver quick answers to time-sensitive questions, delivered and formatted to distill complex issues to bottom line results.


COVERLAB staff specialize in Geographic Information Systems (GIS)>. We produce a variety of geospatial mapping and analysis products for decision planning.

  • Geocoding services – we map ~98% of North Carolina CMV crashes
  • Reference layer development and maintenance
  • Calculated map “layers” that allow supervisors to identify roads and bridges that are vulnerable to damage from overweight vehicles
  • Interactive web maps for seeing relationships between crashes and enforcement
  • Geo-statistical services – crash rate and hot spot layers
  • Printed large format plots and handouts
  • Geospatial analysis (buffer, overlay, intersect, etc.)

We provide comprehensive Integrated Technology Deployment (ITD) program support, grant writing assistance, business continuance services, and performance measurement analytics.


ITD dashboards show out-of-service and weight violations by time of day and day of week, virtual weigh station trends, alert frequencies, multiple “offenders”, and enforcement locations.

Research, Education, and Training

COVERLAB staff provide field and special study research services to answer operations planning and operational effectiveness questions.


COVERLAB staff train troop supervisors and command staff to use decision support tools to help identify and prioritize enforcement activities that improve effectiveness.


We offer a variety of webinar, multimedia, and video services, as well as a spacious 12-seat computer lab.


COVERLAB is a program hosted at the Institute for Transportation Research and Education (ITRE), and supported by the Commercial Vehicle Enforcement section of the North Carolina State Highway Patrol.
