Assessment of ND County and Local Road Needs
Study Updates

Staff Collect Data on Gravel Costs Across the State

Oct. 21, 2019 - This month, more than 2,000 surveys are being mailed to county and township officials across the state to obtain updated information about cost of gravel from local pits, trucking costs, placement costs, blading costs and costs of any dust suppressants used. The survey also asks questions about blading frequency and graveling frequency and other maintenance costs. The survey was designed with help from an advisory group made up of county road officials. Information gathered will help researchers estimate investment needs for maintaining the state's more than 60,000 miles of gravel roads.

Uniformity in completing the survey is critical. UGPTI will host a training webinar Oct. 23 from 2-3:30 p.m. CT. Invitations will be mailed to all road superintendents. The webinar will be available for replay on the UGPTI website.

Pavement Data Will Aid Local Road Managers via GRIT

Oct. 21, 2019 - Ride quality data and video images collected on about 6,000 miles of paved county roads across the state are being calibrated and geo-referenced to roadways so they can be included in UGPTI's Geographic Roadway Information Tool (GRIT). The information, collected by UGPTI staff this summer, will enhance the wealth of information available to local road managers through GRIT, an online asset management tool. Local roadway managers can enter data such as pavement type and age, base thickness, shoulder width, etc. That combination of information helps local road managers identify road segments that need maintenance and provides key information for UGPTI's effort to project road investment needs across the state.

Traffic Forecast Model Development Progresses for Road Study

Sept. 16, 2019 - Alan Dybing, Tim Horner, and Denver Tolliver of UGPTI met with staff of the Oil and Gas Division of the North Dakota Industrial Division in late August to obtain the latest estimates of energy development in the state. Oil well drilling estimates, along with updated data on inbound and outbound truck, rail and pipeline shipments for each well, will be used to develop comprehensive traffic models for predicting traffic across the state for the next 20 years. Those predictions will be used to estimate road and bridge investment needs for the county and township roads.

Traffic and Pavement Data Collection Nears Completion for Road Study

Sept. 13, 2019 - UGPTI staff members traveled more than 15,000 miles crisscrossing the state to collect data on traffic and pavement condition data on county roads. Students and staff from UGPTI canvassed the eastern third of the state while a consultant gathered data in the western part of the state. NDDOT is assisting with the central part of the state as part of its scheduled traffic counts. Traffic counts will be used to assess traffic volumes and flows across the state and in models to predict future road use.

Researchers used cell phone-based apps to gather pavement roughness data and take corresponding photos of all paved county roads across the entire state. The information will be used to evaluate the current condition of county roads and provide data for the Geographic Roadway Inventory Tool (GRIT) to help local road leaders make decisions on road maintenance and improvements.

Overall, the information will be used as a basis for developing predictions of road and bridge investment needs as directed by the North Dakota Legislature.
