  Planned disruptions such as highway constructions are commonplace nowadays
and the communities living near these disruptions generally tend to be
environmental justice communities -- low socioeconomic status with
disproportionately high and adverse human health and environmental effects. A
major concern is that such activities negatively impact people's well-being by
disrupting their daily commutes via frequent road closures and increased dust
and air pollution. This paper addresses this concern by developing a
personalized navigation service called PureNav to mitigate the negative impacts
of disruptions in daily commutes on people's well-being. PureNav has been
designed using active engagement with four environmental justice communities
affected by major highway construction. It has been deployed in the real world
among the members of the four communities, and a detailed analysis of the data
collected from this deployment as well as surveys show that PureNav is
potentially useful in improving people's well-being. The paper describes the
design, implementation, and evaluation of PureNav, and offers suggestions for
further improving its efficacy.
