Signal Warrant Analysis Course

This course covers the nine signal warrants in the MUTCD. Each warrant is reviewed and shown how to interpret and explain how to apply to real-life situations. The participants are led in a discussion of the advantages and disadvantages of signalization and potential non-signalized solutions for improving an intersection’s operations. Class teams are formed and a workshop is held to take field data and evaluate a sample intersection to determine if any of the intersection warrants are met. The HCS warrant analysis program is applied to the class program and demonstrated to the class. A workbook is provided and a general agenda for the one-day course follows:

Welcome and Introductions Roster sign-in, workbook distribution, agenda, schedule, informal discussion.
Manual on Uniform Control Devices Overview of definitions and purposes of signal warrants from within the MUTCD.
