Intelligent Transportation Systems
As of 2014, 54% of the earth’s population resides in urban areas, a percentage expected to reach 66% by 2050. This increase would amount to 2.5 billion people added to urban populations . At the same time, there are now 28 megacities (with population ≥10 million) worldwide, accounting for 22% of the world’s urban dwellers, and projections indicate more than 41 megacities by 2030. It stands to reason that the management and sustainability of urban areas have become one of the most critical challenges our societies face today, leading to a quest for “smart” cities. Among the many functions a city supports, transportation dominates in terms of resource consumption, strain on the environment, and frustration of its citizens. Commuter delays have risen by 260% over the past 25 years and 28% of U.S. primary energy is now used in transportation . It is estimated that the cumulative cost of traffic congestion by 2030 will reach $2.8 trillion .
