Highway Safety Data: Costs, Quality, and Strategies for Improvement. ResearchReport

摘要

The goal of this project was to analyze the collection and management of highwaysafety data by identifying issues and costs, and proposing means of resolving those issues and reducing the costs. Initial emphasis addressed known elements of the highway safety system with emphasis on collecting and storing relevant data. Sources included the literature and what the States, local agencies, and researchers throughout the Nation were doing to improve data handling for the three largest sources: traffic crash, roadway inventory, and crash injury (emergency medical services and trauma). A major thrust of the research was directed toward identifying the costs of collecting, reporting, and managing safety data. Lack of cost data or lack of applicability of most data collected for roadway inventory and crash injury preclude an extension of the cost model beyond that of crash reporting. Additionally the report estimates a range of costs by severity of crash, number of vehicles involved, and region of the country. Finally a set of strategies was identified along with goals to be met. The research team identified 23 strategies which were capable of being introduced without requiring substantial additional effort. The report concludes with discussion of how strategies may be grouped and introduced as a package. All of
