TRAC - IT uses cell phones to collect travel behavior data

egies are designed to motivate people to modify their travel choices, particularly the drive-alone preference. TDM strategies and policies seek to increase transportation system efficiency and achieve specific objectives, such as reduced traffic congestion, road and parking cost savings, increased safety, improved mobility for non-drivers, energy conservation, and pollution emission reductions. Marketing these strategies to the “consumer” in an effective way that results in behavioral changes requires a sustained understanding of how, when, where, and why people travel. Therefore, accurate, timely, and comprehensive data are vital in understanding/influencing consumer behavior. The same data are essential for many planning purposes including future demand assessments and long-range transportation plans.
