Since Community Buses have lower fares, VTA should use them on routes that are short and/or only serve a certain community. Examples are the 47, 48, bring back the 15 and perhaps another bus running between Morgan Hill and San Martin Caltrains, the 40, etc.
Also timed transfers between short route Community buses with long route normal buses, Express buses, and Light Rail lines would ease travel on VTA. Any Light Rail station that is served by bus should have timed transfers. If not all the time at least during peak commute hours.
