5 <br /> <br />and infrastructure since the program began in 2018, including the NDDOT’s inaugural Vision Zero Safety <br />Program Award in 2019. <br />Cass County uses a systemic approach to highway safety. All new construction and maintenance overlays <br />include the use of edge line rumble strip installation to separate the roadway from the shoulder while leaving <br />on-off gaps for bicycle safety. This method can help reduce crashes that occur from inadvertently leaving the <br />roadway. Lane departure is the most common type of crash resulting in injuries in rural areas. Nearly all asphalt <br />County Highways have rumble strips, except on older concrete roads and highways within City limits. <br />Intersection improvements and safety enhancements are implemented where collisions have historically <br />happened or where collisions may be likely. Using a systemic approach, improvements such as flashing signals <br />on stop and stop ahead signs, rumble strips, and improved signage have proven successful in past projects. <br />Striping is performed annually on all paved County Highways. <br />Highway Access Ordinance #2007-1 was developed to reduce the number of access points on County Highways <br />for more efficient and safe operation. With design speeds on County Highways at 55 – 65 mph and the <br />reduction of accesses to one per ¼ mile, a County Highway can operate with less interruption and more <br />predictable intersections. In addition, the Ordinance regulates the design of the approach by increasing the <br />slope of the approach to reduce severity in off road crashes. <br />Cass County uses crash data provided by the NDDOT in planning and implementing safety enhancements. When <br />significant crashes occur on Cass County Highways, a general reconnaissance is performed by the County <br />Engineer or Highway Superintendent to assess the road condition and variables that may be present. <br />Signs and Traffic Control Devices <br />Cass County utilizes the 2009 Edition of the Manual on Uniform Traffic Control <br />Devices (MUTCD) from the US Department of Transportation, Federal Highway <br />Administration. The MUTCD is the standard for traffic control devices and has <br />been adopted by the NDDOT. Cass County maintains an inventory of their signs <br />indicating condition and location in a geo-database. <br />Local Road Safety Plan <br />In 2014 the NDDOT sponsored a statewide Local Road Safety Plan (LRSP) for <br />counties. The purpose of this plan was to develop the following: <br />1. Establish safety emphasis areas <br />2. High priority safety strategies <br />3. Identify at-risk locations <br />4. Develop safety investment options <br />5. Identify high priority safety projects, both proactive and reactive <br />6. Position local agencies to compete for safety funds <br />7. Foster safety culture among local stakeholders <br />
