Use of Probe Data for Arterial Roadway Travel Time Estimation and Freeway Medium-term Travel Time Prediction

Urban traffic congestion is a problem that plagues many cities in the United States. One approach to alleviating this congestion is to provide drivers with better travel time information so that they can make better departure time and routing decisions. This research project focuses on two efforts: (1) validating the use of probe data to estimate arterial travel times and (2) validating and developing techniques to predict freeway travel times over a two to four-hour window. With regards to arterial travel time estimation the objective is two-fold. The first goal is a comprehensive validation of INRIX arterial probe data. In the validation the variability and reliability of arterial data in different corridors equipped with permanent and portable Bluetooth detectors will be studied under different traffic conditions. The second objective is to develop a methodology for augmenting INRIX data with other data sources in order to improve the data quality. With regards to freeway travel time prediction the objective is also two-fold. The first objective is to validate existing medium-term travel time prediction algorithms along one or two corridors in the state of Virginia. The second objective is to enhance the medium-term prediction accuracy using various artificial intelligence and traffic modeling techniques. Please submit a proposal with the following headings, at a minimum. Additional headings and information may be provided.
