Contact Hours



The Intersection Capacity Analysis Course covers the Highway Capacity Procedure for determining the capacity of individual signalized and two-way stop intersections.  The TRB Highway Capacity Manual procedures are presented as the basis of the analysis.  The relationship between capacity and level of service are discussed along with the impact of geometric configurations and signal timing.  Saturation flow and what characteristics account for adjustments needed for saturation flow are reviewed.  The capacity and level of service procedures including critical gaps are presented to the class as well.

Manual procedures for determining level of service through field observation are covered along with an HCS software analysis as well.  If time and weather permits a short field trip to observe and collect field data may be held.
