They generally run as local lines around the two termini, then travel along freeways or major highways with no stops in the middle portions of the route. Express versions of regional routes run as limited lines through the two end portions of the route, then follow the same middle segment. Some routes provide service to rural areas, traveling along multi-lane highways with limited stops.
