Summary
This document is the 2021 Annual Report for Alabama’s Highway Safety Improvement Program (HSIP), administered by the Alabama Department of Transportation (ALDOT). The report addresses the state’s efforts to reduce fatalities and serious injuries on public roads, aligning with the “Toward Zero Deaths” initiative and the Alabama Strategic Highway Safety Plan (SHSP). The program is motivated by a recent uptick in fatalities after a decade of decline, with ALDOT failing to meet 2019 safety targets. The HSIP focuses on four SHSP emphasis areas: High-Risk Behavior, Infrastructure and Operations, At-Risk Road Users, and Decision and Performance Improvement. The methodology involves a data-driven approach utilizing crash statistics, exposure data, and benefit-cost analysis to prioritize projects. ALDOT’s Traffic & Safety Operations Section (TSOS) manages funding through a statewide competitive application process, ensuring projects address specific safety issues identified via the Critical Analysis Reporting Environment (CARE) software. The program employs systemic countermeasures, including the Interstate Median Barrier Program, Shoulder Widening Program, and Horizontal Curve Safety Program. Additionally, ALDOT collaborates with universities to develop Alabama-specific Safety Performance Functions (SPFs) and planning tools like ALSAFE. Non-infrastructure efforts include targeted enforcement campaigns, public education initiatives, and technical assistance for local roads through the Safety Technical Assistance for Counties and Cities (STACC) program. Key findings and activities reported include the implementation of infrastructure projects such as median cable installations and curve resigning to address roadway departure crashes. The report details the expansion of safety culture initiatives, including the development of an Alabama Roundabout Guide and the deployment of the Emergency Medical Services Information System (EMSIS) for better data collection. ALDOT also conducted peer roundtables to identify necessary safety skills for staff and launched marketing campaigns reaching over 35 million views. The program supports local agencies by funding low-cost safety improvements and sponsoring the development of Local Road Safety Plans for all 67 counties. The significance of the report lies in its comprehensive documentation of Alabama’s integrated safety strategy, combining engineering, enforcement, education, and emergency response. By transitioning to more systemic, data-informed project selection and enhancing local road safety capabilities, ALDOT aims to reverse the recent increase in fatalities. The report highlights the importance of inter-agency coordination and the adoption of advanced analytical tools to meet the long-term goal of reducing fatalities by 50% over 20 years.
Key finding
The Alabama Highway Safety Improvement Program utilizes a multi-faceted approach combining infrastructure improvements, data-driven project selection, and behavioral outreach to reduce crashes, though recent increases in fatalities have necessitated new strategic planning to meet safety targets.
