PREDICTING THE 24-HOUR DELAY AT SIGNALIZED INTERSECTIONS

For the purpose of making the most effective use of available transportation funds, the Washington State Department of Transportation (WSDOT) developed a statewide cost-benefit method for prioritizing new capacity improvement projects. WSDOT decided that the most equitable measure of operational benefits associated with transportation improvements would be based on 24-hour delay analysis. Collecting information for a 24-hour period for every intersection that needed to be analyzed was impractical; therefore, a new method for predicting 24-hour delay at signalized intersections was developed. This article describes the study conducted to develop the new method, including study design, regression analysis, error analysis, limitations and applications. and sample calculation.
