Project detail
Roadmap/Focus area(s):   Comprehensive Approach to Safety
Project Description:   The Highway Safety Information System is a multistate database that contains crash, roadway inventory, and traffic volume data for a select group of States. The data are available to be used for the study of highway safety.
Goals:   The Highway Safety Information System is used in support of the Federal Highway Administration safety research program and to provide input to the program and policy decisions. The Highway Safety Information System is also available to analysts conducting research under the National Cooperative Highway Research Program, university researchers, and others involved in the study of highway safety.
Background Information:   An important part of the decisionmaking process is the potential impact on the safety of the highway users. Informed decisionmaking requires an understanding of how safety is affected by the geometric design of the roadway, the selection and placement of roadside hardware, the use of traffic control measures, the size and performance capabilities of the vehicles, and the needs and abilities of the users. This understanding can be developed through sound analysis of information about crashes, roadway geometrics, traffic control devices, traffic volume data, and the location of hardware and obstacles on the roadside. The data must be present in computerized files and easily linked so that data can be rapidly assembled and used for analysis.

Research report
Other Information:   The Highway Safety Information System uses data already being collected by States for the management of the highway system, and for the study of highway safety. The Highway Safety Information System is a roadway-based system that provides quality data on a large number of accident, roadway, and traffic variables. The data are acquired annually from a select group of States, processed into a common computer format, documented, and prepared for analysis.
Deliverables: 1. Name: Data and evaluations of safety improvements.
Product Type(s): Research report, Data, Techbrief
Description: This deliverable involves extracting State crash, geometric, and traffic files. Reports and summaries of safety effectiveness and evaluations for highway safety improvements will also be prepared.
