The relationship between the shape of transportation networks and the optimal locations and allocations of human activities is examined in this volume. The author uses innovative as well as existing techniques to "measure" the shape of a transportation network. Simulations are performed on different toy-networks: several transportation networks are designed and their effects on location-allocation results are tested on different markets. The author then attempts to discover how the modelling results are affected by negative externalities or zone pricing policies. Finally, these results are applied to real world situations, illustrating and confirming the results of the simulations performed on toy-networks. This volume should be considered as an interesting and original approach for location-modellers as well as planners. "Transportation Networks and the Optimal Location of Human Activities" should also appeal to geographers, spatial economists, location-allocation practitioners and transportation researchers.
