Abstract:
A framework for performance evaluation and active management of a transportation network infrastructure reconstructs traffic flow profiles by modeling annual average daily traffic data and collected traffic speed data to estimate an hourly traffic flow profile for a roadway segment, or link. Total daily flow for a link is derived from the corresponding annual average daily traffic data for that link, and is adjusting by the day of week and the monthly seasonal factors. An hourly flow distribution profile for a roadway link is then constructed using the traffic speed data relative to that link.
