Planning Support Systems

Designing tools for other people seems helpful, but the history of the various ‘Planning Support Systems’ strongly suggests they are highly localized and context specific to answer certain questions in a certain way. Envision Tomorrow+ has seen only limited use, for example.  Unless a compliance agency mandates/encourages their use (MOVES/TBEST/STOPS), there is limited traction. They have to become (in the way travel models have) part of the institutional context.
