This guidebook should aid the user in developing a basic understanding of traffic data collection principles and procedures.

Furthermore, this document investigates some of the challenges associated with a traffic monitoring program including variability in traffic, adjustment factors, and strategies for assisting with under-funded programs. This guidebook does not attempt to cover every aspect and detail of traffic monitoring but provides a starting point that leads the user to a successful traffic monitoring program.
