Planning and environmental studies involving managed lanes still have difficulty determining how to effectively evaluate project alternatives from an equity perspective. To most people, “equity” is ubiquitous with income, but this is a narrow focus that limits the scope of what can be considered equity, and indeed this can be true when it comes to

Bats are found on every continent except Antarctica and play a crucial role in our ecosystems from pollination to pest control to seed dispersal. Although bats use natural roosts such as trees and caves, many species also use anthropogenic roosts such as buildings and transportation structures. Because of this, a growing number of transportation de
