Design Exception In-Service Monitoring Program Development

This study evaluates various possible program designs for in-service monitoring of design exceptions (DEs) for the Georgia Department of Transportation. The study recommends a multi-tier stepwise approach to the evaluation of DEs. Specifically, the proposed monitoring program aims to: (1) identify DE-associated hazards that have/could result in a fatality or serious injury at a site, (2) detect and identify DE-related increases in crash rate, and (3) detect and identify any DE-related increase in crash severity. The proposed program was designed to minimize additional data collection requirements and ongoing time and resource requirements for implementation. An important step in minimizing these resource requirements is to ensure that the information necessary for conducting these future audits is available early in the design exception review process. The proposed changes to the design exception request process are relatively minor but will pay important dividends in reducing future monitoring costs. In particular, these process changes should be implemented as soon as possible.
