These different types of accessibility have significant economic development and productivity effects that are particularly important for transportation planners who need to evaluate proposals for freight and passenger modal investments connecting communities and intermodal facilities. This publication brings together three complementary perspectives: (a) transportation planning literature that distinguishes types of transportation investment and plans; (b) site location literature that defines business location decision processes and their spatial scale, and (c) economic research that provides a basis for defining scale economies and productivity effects.
This presents results of a new US study that develops statistical relationships between types of accessibility and industries in terms of their relative concentration and productivity at a county level. It discusses the implications of these findings in terms practical applications for improving transportation investment planning and needs for further research.
