Developing a New Measure of Transportation Insecurity: An Exploratory Factor analysis
A methodological article published in Survey Practice is where the developers of the Transportation Security Index first define the concept of transportation insecurity. Using qualitative research, candidate questions for the index are developed. Using exploratory factor analysis, a preliminary 16-question Transportation Security Index is identified that includes questions tapping into the material and relational symptoms of transportation insecurity.
New Hampshire is one of the fastest-aging states in the country. The TSI is giving us, for the first time, a way to gather local, nuanced data about transportation insecurity and unmet transportation needs, especially as more residents age in place here. That’s going to be essential to effective planning and investment moving forward.
