I hope they start pricing lots differently based on how popular they are. Fore example, according to the MBTA, Braintree fills up every weekday. They should raise the price $0.25/day each month, until the garage is no longer full every day. Also, they could add more parking to Braintree, if it seems like it will be profitable.
Hell yes. There are lots that are full before 8 AM (e.g. Oak Grove), while other lots never pass 50% (e.g. West Newton CR). These should not all be using the same pricing structure.
Oak Grove has some "priority monthly parking" program or something like that where people can pay (a lot) monthly and have a reserved spot for them self at the station. I wonder if they would expand that program. Also I like the idea of the demand-based pricing you propose. They should complement increased parking fees with better access though (bus connections, bike parking, kiss and rides).
I've noted that Pine Banks Automotive on Main Street appears to lease 30 or so spots in their lot to commuters. I'd love to know what they're getting for those spots.
If this gets the T to do more TOD, then that sounds great. The article that I read did mention they were thinking of building garages (underground?) to replace the surface spaces though. Are they talking about surface lots for T employees or lots next to stations for commuters?
Every station with significant surface parking should be leased to a developer, similar to what they did with Woodland.
