Travel-time reliability is becoming more important to commuters. The main goal of this research is to better understand the value of travel-time reliability in relation to other components of a commute. Researchers will present commuters with three customized, alternative routes to and from work: (1) primarily freeway, (2) primarily arterial roads, and (3) other streets. Researchers will collect data from drivers after each commute. The added realism of this data collection method will allow researchers to incorporate the value of travel-time reliability into route preference models. An additional objective of the project is to make information about local road networks more available to drivers.
