New development places new burdens on the local and regional transportation system, along with associated effects on air quality and greenhouse gas emissions, and mitigating those effects can cost a lot of money. As we look at a potential development site, how do we figure out the mixture and placement of land uses that will minimize transportation impacts? Plan+ is a one-stop application that quickly analyzes the traffic and parking parameters for a development site, testing a wide variety of land use scenarios and focusing in on the scenario that achieves the greatest transportation efficiency.
