Conclusion: The Transit-Oriented Region
One cannot hate sprawl but also hate density, and neither can one hate tax dollars being spent on public transit while highways remain un-tolled and parking is free. There are costs and benefits to all choices and having a model to see the scale of the operation and volume of opportunity helps decision makers, including the interested public, to make better-informed decisions.
Ultimately, having goals and targets make us more aware of the impact on the smaller and larger scale of urban design of every choice we make. This is not novel, but having a model to elucidate targets such as GHG, VKT and POS is new and, potentially, useful as cities and regions become more complex and populous.
