Intersections Calculators Traffic Control Need Calculator

Traffic Control Need Calculator

Good Sight Distance
Major Street	Minor Street
24 Hour Traffic Volume (Total of Both Directions)	Peak Hour Traffic Volume (Highest Hour, Both Approaches Combined)
Average Hourly Traffic Volume The Average Hourly Traffic Volume is based on the Highest 8 Hour Count. Counts are to be taken on the lanes approaching the intersection. (Total of Both Directions)	Average Hourly Traffic Volume Based on an 8 Hour Count, these count times must coincide with the same 8 hour Major Street Count Times. Volumes should include Vehicles, Bikes and Pedestrians. Counts are to be taken on the lanes approaching the intersection. (Total of Both Directions)
Crashes Per Year
Crashes Per 2 Years
85^th Percentile Speed

This calculator is the primary step in determining the type of intersection control,
but is only one element in an engineering study. See instructions for additional guidance.
