Each day, millions of people depend on their public transportation systems and roadways. With ever increasing populations and the rise in mobility that comes with it, nations around the world are facing a serious land transportation challenge. The rapid urbanization and shifts in population density coupled with limited road system capabilities has resulted in constantly increasing commute times, fuel consumption and air pollution thereby reducing the efficiency of the transportation infrastructure. These inefficiencies are also seen to be having grave environmental, social and economic consequences.
