Summary
This report addresses the need to modernize and unify traffic accident reporting systems in South Dakota, specifically aiming to integrate commercial and non-commercial accident data into a single, efficient framework. The motivation stems from the inefficiencies of the existing system, which relies on disparate databases, manual paper-based processes, and fragmented forms that lack integration with national initiatives like the Model Minimum Uniform Crash Criteria (MMUCC), Fatal Analysis Reporting System (FARS), and SAFETYNET. The study sought to define functional requirements, establish a logical data architecture, and develop a migration plan for a new Accident Reporting System that improves data accessibility, analysis capabilities, and resource utilization. The research methodology involved a comprehensive review of current business processes, forms, and data structures used by state, federal, and local agencies. The authors conducted workshops with stakeholders, including law enforcement, transportation officials, and industry representatives, to gather input on functional requirements and form design. They analyzed existing systems, identified gaps in compliance and data collection, and evaluated potential technological solutions. The study produced a preliminary redesign of the South Dakota Traffic Accident Report Form, a detailed data model, and a process model to support the transition to a unified electronic system. Key findings revealed significant challenges in redesigning the crash report form, particularly balancing the desire for a single-page form with the need for comprehensive data collection and MMUCC compliance. The study identified inefficient manual processes, inconsistent adherence to state reporting policies across jurisdictions, and difficulties in accurately collecting commercial vehicle information. It concluded that the current mainframe-based database (ADABAS) was incapable of supporting modern needs such as web access and customized queries. The report recommended adopting TraCS (Traffic Accident Reconstruction and Crash System) as the front-end data collection tool and implementing a new client/server relational database using Microsoft SQL Server to serve as the central repository. This architecture would automate data transfer to national systems, reduce human error, and support advanced analysis tools like GIS and Online Analytical Processing (OLAP). The significance of this work lies in its provision of a strategic roadmap for upgrading South Dakota’s accident reporting infrastructure. By recommending a hybrid migration plan that combines existing software with new database technologies, the study aims to reduce administrative burdens, improve data accuracy, and enhance the state’s ability to support national safety initiatives. The recommendations emphasize the need for comprehensive law enforcement training beyond mere form usage, focusing on policy adherence and proper data capture. Ultimately, the proposed system is designed to provide a more integrated, flexible, and efficient means of recording, managing, and analyzing traffic accident information, thereby supporting better decision-making for traffic safety and infrastructure planning.
Key finding
Adopting the TraCS system for front-end data collection and a client-server relational database architecture is recommended to improve efficiency and data quality in accident reporting.
