Safety Data: Costs, Quality, and Strategies for Improvement. Executive Summary

摘要

The Intermodal Safety and Transportation Efficiency Act (ISTEA), established in1992, was designed to improve the performance of statewide and metropolitan transportation systems. To optimize system performance, the ISTEA required development and implementation of six management systems, including the highway Safety Management System (SMS). Quality data are needed at a reasonable cost to support effective safety decisions. The objective of the project was to examine the costs and quality of safety data and to identify improvement strategies. To meet the objectives of the project and to make it feasible given the project resources, the project's scope was narrowed to three key sources: the crash report, roadway inventories, and medical records. The primary focus was on crash reporting. Within the medical source, the focus was upn data regarding driver condition prior to crash, and injury severity, since these are of high interest to the highway community.
