TRAFFIC

Design & Operation

Traffic Impact Studies provide an analysis of traffic generated by a proposed new land use and its effect on the existing roadway network. This analysis is used to determine which intersections are presently experiencing problems, as well as identifying capacity problems that will develop as a result of the proposed land use. In addition, First Group will conduct the following list of studies to evaluate improvements requested by local agencies to determine if they are, in fact, needed.

  • Level of Service
  • Internal Site Flow
  • Capacity
  • Need for Additional Turn Lanes
  • Need for Traffic Signals
  • Accident Analysis
  • Traffic Counts
  • Parking Design


It is important to note that these studies are not only useful in determining what improvements are necessary, but also if these improvements are the direct result of the proposed land use or from existing conditions.
