Evaluation of Freeway Travel Time Variability and Reliability under Adverse Weather with TRANSMIT Data
In addition to delay, the variability and reliability of travel time has been of concern to motorists on their daily travel, especially during peak periods. Traffic congestion has caused many detrimental effects including higher fuel consumption, more vehicle emissions, increased accidents, as well as greater tension due to uncertain travel time. The objective of this study is to examine freeway travel time variability and reliability under different traffic and weather conditions with the use of TRANSMIT data collected by roadside readers deployed on a 40-mile segment of the Interstate I-287 in New Jersey. Travel time variability and reliability measures including mean travel time, the 95th percentile travel time, travel time index, buffer index, and planning time index are investigated under various circumstances, such as adverse weather.
