Construction Zone Safety & Crash Analysis

The Federal Highway Administration’s Manual on Uniform Traffic Control Devices (MUTCD) defines the standards used by road managers to install and maintain traffic control devices.  Minimum standards for a variety of traffic work zone applications are displayed within this manual.  We can provide a comprehensive traffic work zone evaluation and crash analysis, based upon, but not limited to, the following experience and training:

Some of the many factors that we evaluate include, the time available for the motorist to perceive, recognize, and react to a traffic control work zone, the existing lighting and weather conditions, vehicle speeds, the complexity and number of decisions presented to the motorist, the expectations of the motorist, the traffic control work zone appearance and conspicuity, the wide range of perception and reaction times of the motoring public, and changing conditions for the duration of the traffic control work zone project.  

  Shown below are examples of Temporary Traffic Control projects.
