Development of Congestion Factors for Adjusting Traffic Counts During Congested Periods: Phase 1 - Literature Review and Survey

The goal of this project is to develop congestion factors suitable for use by the Florida Department of Transportation to adjust traffic counts during congested periods on urbanized roadway sections experiencing both recurring and nonrecurring congestion. In Phase 1 of this project, the objective is to conduct a detailed literature search of both published and unpublished material as well as to conduct a survey of State DOTs to solicit information on the state-of-art and the state-of-practice in traffic data collection particularly during congested periods.
