It seems really poorly modeled, I think they might have only based it off transit ridership in the zone of influence of the stations. Having termini at 695 / 83 in the north and 95 in the south would have created a major park and ride and opportunity at both ends, honestly in ways that no existing route in Baltimore realizes - the light rail is too slow and the existing subway doesn't have an easily accessible station from 695, you have to go to Old Court which is like 10 minutes of driving just off the beltway alone.
