Work Zone Traffic Analysis (WZTA) is the process of evaluating and determining the safety and mobility impacts within a construction, maintenance, or rehabilitation project. Establishing a procedure for analysing work zone mobility and safety impacts aids agencies in the planning, decision-making, design, and financial aspects of the project. This report provides guidance on WZTA applications and presents the steps involved in the application of maintenance of traffic alternatives analysis (MOTAA) and decision framework. It contains step-by-step guidance to assist the analyst in determining the most suitable tools to perform the work zone analysis and presents a procedure for developing and applying models to work zone analysis. To illustrate the MOTAA process and decision framework contained in this guidebook, a variety of WZTA case studies are presented to demonstrate a diverse set of MOTAA applications. (Author/publisher)
