This implementation guide describes the conceptual framework, data requirements, and computational procedures for determining the safety and mobility impacts of work zones in Texas. Researchers designed the framework and procedures to assist district-level personnel who have responsibility for work zone safety and mobility impact reviews of significant projects as required by Texas Department of Transportation (TxDOT) policy. In this guide, researchers describe the types of impact monitoring and analysis that can occur as part of ongoing project activities and those that can be performed during post-project reviews. Analysis procedures are presented to assist in determining which projects should be targeted for regular reviews of crash data during the project, as well as the increase in crash frequency that is indicative of unusual safety concerns that should be investigated further through field observations. Researchers also present analysis procedures to guide district personnel in determining the queue lengths, individual vehicle delays, and total vehicle-hours of delay that are created during temporary lane closures in a project.
