Work Zone Analysis Guide

The Federal Highway Administration’s Rule on Work Zone Safety and Mobility, 23 CFR 620 Subpart J, requires every state to identify methods of improving roadway safety and mobility in and around the work zone. In response to this Rule, the Maryland State Highway Administration has prepared Transportation Management Plans: Guidelines for Development, Implementation and Assessment. One of the components of assessing work zone safety and mobility impacts for the Transportation Management Plan is work zone traffic analysis, which is the subject of this guide. The purpose of this document is to provide guidance on evaluating the impacts of work zones on roadway capacity.
