The document introduces the concept of exponential planning as an overlay on traditional planning processes. Exponential planning is designed to evaluate future trends and risks that could impact government projects. It involves defining a project or element, mapping adjacent impact areas, identifying macro trends, and potential impacts. Prediction statements may then be integrated into the overall plan. An example is provided where exponential planning is applied to modifications of MOPAC in Austin to ease traffic. Adjacent impact areas like e-commerce, self-driving cars, ridesharing and individual behavior are analyzed for impacts on transportation needs.
