Evaluating Transportation Improvements Within Cities Using Quantitative Spatial Models

Abstract: I describe the use of quantitative spatial models (QSMs) to evaluate the effects of transportation infrastructure within cities. After discussing the motivation for QSMs relative to other economic measurement techniques, I develop a simple QSM and detail the components that enter into the model. Next, I consider identification challenges and practical implementation. Finally, I highlight several shortcomings common in applications of QSMs, as well as growth areas where QSMs show promise for future development.
