The Transportation Security Index

Reliable access to transportation is essential to holding a job, grocery shopping, and getting to school, child care, social services, and other activities. Transportation insecurity — the experience of being unable to move from place to place in a safe or timely manner — has important consequences for people’s ability to connect to opportunity and flourish.

University of Michigan researchers have developed the first validated measure of transportation security that offers insights into who experiences transportation insecurity and enables researchers and practitioners to determine both the causes and consequences of transportation insecurity as well as identify which interventions can improve this condition.
