Master's of Sustainable Transportation @ UW

I'm interested in the University of Washington's online Master's in Sustainable Transportation but was unsure if such a program would stand up well in the world of urban planning (compared to a MUP). Would I be shooting myself in my foot by getting a degree in such a specific subject rather than the broad field of urban planning? I'm having a hard time finding any additional info on the program and was wondering if anyone had heard anything or know of anyone that went through this program. I was thinking that it might be a good program to pair with a graduate certificate in GIS to round it out, especially since its only one course a semester.

Here's the link to the program: https://www.sustainable-transportation.uw.edu/

Anyone know anything about this program? Is a MST useful? Thanks for any help!!
