The question of which came first, vehicle infrastructure design may, therefore, be moot. Examples and illustrations that will be the focus of my efforts to present applications and benefits, are homely, simplistic. To some they will register with a ho-hum, while to others they may seem beyond the pale. Following definition, I will follow my charge to range widely across and between modes and to consider various possible impacts, i.e., safety, economic, capital investment, environmental, cultural, efficiency, productivity and institutional aspects. Today, vehicles are designed with a static representation of the infrastructure.
Infrastructure is designed with a static representation of vehicles.
Transportation system performance can be improved through bringing together the design of vehicles and infrastructure. From the perspective of the transportation system, individuals, materials and information are elements to be moved, Some means is employed to move these elements from one point to another -the means of movement is a form of vehicle. The environment is in part that which is constructed for the purpose of transportation, and in part the natural and social setting of the construction. While David s last point provides the operative definition, I believe the several quotes from his seminal paper shore up the concept and give the robustness necessary for full future development of the SVID concept. In the Los Alamos paper cited earlier, Albright suggested three criteria for SVID project selection.
