Description of methodology:
The locations above are the top 5% of the locations identified in the ND Annual High Crash Locations Analysis. For the Annual High Crash Locations Analysis the top 50 urban intersection/link locations, top 15 Interstate highway locations, and top 15 rural public highway locations are identified and ranked. All severity of crashes are included. The ranking process factors in the total number of crashes at the location, the weighted severity of the crashes, and the crash rate. All three factors are used to arrive at a final rank. Information on all ranked locations is sent to the Cities and NDDOT District Engineers as applicable and they are asked to comment on possible remedies. All comments are compiled and the NDDOT Planning & Programming Division publishes the recommendations and proceeds with project development as appropriate.
Extent of public road coverage:
Rural - all public and Interstate highways, Urban - 13 major cities (population 5,000 and over)
Schedule for updating crash data system to full coverage:
Have statewide crash data covering all public roads, work needs to be done on query system to incorporate crash severity rankings. This should be completed for the next evaluation period.
Years used in data analysis:
2004-2006
