Prviate Shuttle System Used Solely

We are going to use a private company shuttle system since there is no bus stop within 1/4 mile of the site. Is it permissible to use the shuttle system to transport employees to both of the two separate public bus lines? And, if so, do these lines have to be within 2 miles of the project site AND a 5-10 minute drive? Or can these lines be within 2 miles OR a 5-10 minute drive? In other words, one of the bus lines is more than 2 miles away, but without traffic lights, so the stop is reachable in just under 10 minutes. Thank you.
