Traffic Engineering Division

Traffic Studies

The Studies Section is responsible for the collection of all types of traffic data. These include quarterly traffic volume counts at 800 locations throughout the County, turning movement counts, traffic delay determinations, pedestrian counts, speed studies, gap studies, vehicular classification counts and traffic crash diagrams.

The collected data is used by the Metropolitan Planning Division for the County's planning transportation needs and by the Studies Section in making decisions regarding traffic signal warrants, appropriate speed limits, and the placing of various regulations such as turning movement restrictions or restrictions on truck traffic, stop signs, etc.

This section performs periodic inspections of roadways under our jurisdiction (county roads and municipal roads covered by traffic engineering agreements) to insure that traffic controls including signs and pavement markings are maintained in good condition.
