Connectivity (or permeability) refers to the directness of links and the density of connections in a transport network. As connectivity increases, travel distances decrease and route options increase, allowing more direct travel between destinations, creating a more accessible and resilient transportation system (TDM Transport Demand Management Encyclopedia, 2009). Connectivity affects the degree to which transportation networks such as streets, walking and cycling paths, connect people to their destinations (including intermediate destinations such as public transport services).Transportation system improvements can affect economic growth and productivity by changing access to markets and connectivity to intermodal terminals. Roads and transport, railways, ports, aviation and tele-communications are viewed as sinews of the economy and catalysts for social and economic change. They establish forward and backward linkages with the rest of the economy.
