Kevin McCrea (yes, that Kevin McCrea) proposes using some of that there smart technology to deal with winter space saving: Basically charge residents for city space savers embedded with GPS devices that could report to City Hall:
After a snowstorm, when a 'host' shovels out a spot and needs to drive off they put their "Official City of Boston Space Saver" in their spot and log that spot into the 'Space Saver Hub'. They give their account and password and enter when they need to return to the spot. The "Space Saver Hub" uses the GPS embedded into the device to log the location. A display screen on the device could flash "Free until 6 pm" or whatever time the person plans on returning. The host is responsible for keeping the device charged and/or batteries installed.
A 'guest' driving through the neighborhood would have two ways of finding a space to park. One is to look for the flashing displays on space savers, the second is to have their smart phone alert them to available spaces in the neighborhood.
