While we don't have very good information, we do know that broadly speaking, transportation investment makes a positive but small contribution to economic health. Many estimates find that the contribution of public investment to productivity is about a quarter of that which derives from private investment. Most studies to date focus on the correlation between transportation infrastructure and economic activity over a long period of time. These analyses can be accomplished using a production function or a cost function. Production functions by themselves look at the technical relationship between outputs and inputs. Cost functions add in the demand for inputs through inclusion of the price variable. Either way, we need to understand that this analysis occurs within the regional growth process. Thus it is important to anchor these relationships within some type of spatial context. However, most studies haven't yet done this, largely because the analysts don't have the detailed data necessary to make that spatial correspondence. The remainder of this conference presentation looks at the shortcomings with the state of the practice as we currently know it. Following the presentation are the findings of two working groups that developed a combined list of 10 research proposals related to determining the impact of transportation investment on economic health.
