In many urban areas, planners from both disciplines are working to achieve this.
Planners are able to develop general goals without too much difficulty.
But, they lack a set of tools to assess the impacts of the alternative land use and transportation scenarios that are being developed. The Federal Highway Administration has sponsored the development of a prototype model to estimate the full cost of alternative land use patterns. The model estimates monetary and non-monetary costs associated with urban land development at the metropolitan scale. The full cost accounting framework uses average cost data, derived from a variety of national studies, as the default values for the calculation of costs. The first cost estimation path focuses on physical development, including land consumption, existing and projected housing mix, regional employment, and local infrastructure capital and operating costs.
