Resources/Tools
- The Geographic Roadway Inventory Tool is an easy-to-use asset management program developed for county road managers. The development of GRIT was a team effort, led by UGPTI. To ensure the needs of county road managers were met, a steering committee comprised of 10 county transportation leaders and representatives from the ND Department of Transportation, the ND Association of Counties and UGPTI provided feedback and guidance throughout the process. GRIT continues to be enhanced with new and improved features and expanded to other states including Minnesota, South Dakota, and Montana.
- Researchers developed a method to allow user to compare costs associated with different road surfaces. Specifically, the Surface Selection Tool is used to determine costs associated with maintaining roads with different surfaces and selecting the most appropriate road surface for a specific set of circumstances.
- This GIS dashboard displays historical crash information provided by the NDDOT. It depicts all rural road crashes reported to law enforcement agencies in state. The maps and graphs include query options to display contributing factors and crash types commonly of interest with the Vision Zero initiative and other traffic safety planning activities. Information may be viewed in statewide and individual county contexts.
- Researchers worked with the NDDOT Maintenance Division to process hourly speed data from nearly 50 ATR and ESS sites across the State. In addition, hourly weather data is processed from the nearest MDSS sites along with the calculated start and end times for winter storms meeting various criteria. With all this data researchers developed a program to calculate how long after each storm it takes for the traffic speeds to recover to 90% of the pre-storm speeds. A GIS webmap based dashboard was then developed to provide NDDOT Managers a tool to monitor and evaluate all the speed, weather and recovery information for all storms in a winter season.
- This GIS dashboard displays near real-time traffic data from the NDDOT rural Automatic Traffic Recorders along with traffic data from signalized intersections in the Grand Forks and Fargo Metro areas. The maps and graphs include recent and historical traffic volumes along with changes in traffic volumes from the previous year.
- The Truck Weight Calculator provides a convenient way to determine the maximum legal weight that any set of axles on a vehicle/vehicle combination may carry on ND interstate and state highways. The allowable weight on a vehicle/vehicle combination may increase by either adding additional axles or by increasing the distance between axles. The formula for the calculator is a weight-to-length ratio. This formula was enacted by Congress and the State to limit the weight-to-length of a vehicle crossing a bridge.
