Summary

This document is the 2021 Annual Report for the North Dakota Highway Safety Improvement Program (HSIP), administered by the North Dakota Department of Transportation (NDDOT). The report details the state’s efforts to reduce fatalities and serious injuries on public roads, aligning with the federal HSIP requirements and the state’s "ND Vision Zero Plan." The program prioritizes six emphasis areas: lane departure, intersections, alcohol/drug-related incidents, unbelted occupants, speeding/aggressive driving, and young drivers. The HSIP utilizes a dual methodology for project identification: a reactive approach targeting high-crash locations and fatal crash sites, and a systemic approach applying low-cost treatments across broader networks. Projects are solicited annually from local agencies and NDDOT districts, then prioritized through a competitive application process. In the 2021 Federal Fiscal Year, NDDOT programmed $19,085,094 and obligated $20,478,060 in HSIP funds. Notably, 53% of HSIP funds addressed systemic improvements, such as cable median barriers, pavement markings, and rumble strips. Funding also supported local and tribal roads, with $6,590,608 obligated for these jurisdictions. Specific projects included intersection geometry modifications, median barrier installations, and pedestrian crossing enhancements. Safety performance data reveals mixed trends. While the absolute number of fatalities remained stable at 100 in both 2019 and 2020, the fatality rate per hundred million vehicle-miles traveled (HMVMT) increased from 1.020 to 1.140. Similarly, serious injuries rose from 379 to 386, with the serious injury rate increasing from 3.860 to 4.420 per HMVMT. The report notes that vehicle-miles traveled dropped in 2020, which contextualizes the rate increases despite stable fatality counts. NDDOT missed its 2020 fatality rate target (actual 1.116 vs. target 1.106) but met targets for total fatalities, serious injuries, and serious injury rates. The state has set 2022 targets aiming for 96.4 fatalities and a fatality rate of 1.094, supporting a long-term goal of fewer than 75 fatalities by 2025. The significance of this report lies in its assessment of program effectiveness and compliance. NDDOT acknowledges the flattening of the downward fatality trend and the rise in injury rates, prompting internal reviews to adjust strategies. The state continues to integrate evidence-based practices, including Intersection Conflict Warning Systems (ICWS) and plans for environmental sensor stations. The report confirms compliance with federal reporting standards and outlines ongoing efforts to coordinate with regional planning organizations and law enforcement to enhance safety outcomes across both state and local road systems.

Key finding

In 2020, North Dakota recorded 100 fatalities and 386 serious injuries, with the fatality rate increasing and serious injury counts rising despite a decrease in vehicle miles traveled.
