Highway Segments/Intersections Exhibiting the Most Severe Safety Needs(Top 5%)

Location	Comments	Potential Remedies	Estimated Costs	Implementation Impediments
Rural Interstate Highways:
I-29, RP 65: US 10 Interchange Area Fargo	Predominant crash type was rear end (46). Area under construction during all 3 years. Majority of rear end crashes involving traffic congestion due to the construction.	I-29 in this area will continue to be under construction for the next few years. Continue to monitor construction zone crashes and make adjustments to traffic control as appropriate.	None	None
I-94, RP 343: West Fargo Interchange Area	Predominant crash type was ran off the road/rollover (18). Of the 18 crashes 7 involved hitting bridge rail or guardrail, 6 involved ran off the road with no rollover, 5 involved ran off the road and rollover. Weather was the main factor in majority of crashes. District should consider this area a high priority location for snow and ice treatment.	District should consider this area a high priority location for snow and ice treatment.	None	Making this area a priority may result in other areas moving down the priority list.
Rural State Highways:
US 2, RP 140: 1 mile east of Burlington	Predominant crash type was animal (26). Deer crossing signs and distance plaques in place. 6 animal crashes in 2005, 5 run-off-the-road crashes in 2005 with three of them during frost or wet conditions.	2005 showed a decrease in the number of crashes at this location. Increase mowing schedule. It is also recommended the location be monitored to see if the decreasing trend continues.	None	Making this area a priority may result in other areas having delayed mowing.
US 2, RP 337: Arvilla area	Predominant crash type was animal (23). Only 4 animal crashes in 2005. Deer crossing signs and distance plaques in place. A left turn lane for westbound US 2 traffic turning into Arvilla is presently being widened and lengthened.	2005 showed a decrease in the number of crashes at this location. Increase mowing schedule. It is also recommended the location be monitored to see if the decreasing trend continues.	None	Making this area a priority may result in other areas having delayed mowing.
Urban Intersections/Links:
Fargo: 13th Ave S & 44th St S	Predominant crash type was right angle (34). They occurred evenly between the directions.	FMCOG is beginning a corridor study. Limit access from 44th St to right turn only.	$60,000	Must ensure reasonable access is maintained for adjacent development.
Fargo: 4th St N & NP Ave	Predominant crash type was left turn (25), with the majority (19) involving westbound left turning vehicles. In 2003-2004 this intersection was part of a detour route, which increased traffic volumes at the intersection. City installed left turn yield on green ball sign for WB traffic in 2005.	Revise and improve signing, improve pavement markings, and eliminate flashing beacons. If minor improvements do not result in desired crash reduction, collect current traffic data and analyze the possibility of installing a westbound left turn phase.	$15,000	None
Bismarck: 7th St & Front Ave	Predominant crash type was right angle (30) with 19 of them involvingsouthbound and westbound vehicles. Of the 30 right angle crashes 20 involved southbound motorists running the red. Collect current traffic data and review signal timings and clearance intervals. Work with City to also review progression along corridor. Recommend increased red light running law enforcement at this intersection.	Remove inappropriate pedestrian crossings, revise pavement markings, revise vehicular signal indications, revise both signal phase and coordination timings.	$20,000	None

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 rural Interstate highway locations, and top 15 rural State 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 Divisiopublishes the recommendations and proceeds with project development as appropriate.
Extent of public road coverage:		Rural - all State 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 all data into the ranking process. This should be completed for the next evaluation period.
Years used in data analysis:		2003-2005
