Book excerpt: This effort addresses the need for a logic-driven process that the Virginia Department of Transportation can use to allocate resources to run-off-road and fixed-object hazards on diverse secondary road systems. In Virginia, there are approximately 60,000 miles of roadway where guardrail upgrade, installation, or related warning signs or protection may be appropriate to address run-off-road and fixed-object hazards. In this project, an information system was developed to aid the planner in guardrail resource allocation by accounting for the potential crash severities, traffic exposures, costs of treatment, and other factors. A user manual accompanying the report describes the three developed software packages (database, screening, and site evaluation) in detail, including a demonstration of the software in a case study of New Kent County, Virginia.
