Abstract
Travel time and travel time reliability are important performance measures for assessing traffic condition and extent of congestion on a roadway. This study first uses a floating car technique to assess travel time and travel time reliability on a number of Indiana Highways. Then the study goes on to describe the use of Bluetooth technology to collect real travel time data on a freeway and applies it to obtain two weeks of data on Interstate-69 in Indianapolis. An autoregressive model, estimated based on the collected data, is then proposed to predict individual vehicle travel times on a freeway segment. This model includes speed, volume, time of day indicators,...
