Work Zones

Highway work zones necessarily modify normal driving conditions to which motorists are accustomed.  It is necessary that the resulting temporary traffic control devices not only advise of these changes but also provide adequate advance notice of the changes, i.e., time a safe response.  TRC has conducted significant research in the design and application of work zone traffic control. Highway work zones are a significant aspect of TRC’s expertise.  We provide highway agencies and attorneys with research in the areas of traffic engineering, highway design, highway illumination, highway safety, human factors, parking lot design, and roadway illumination.
