Population in the urban areas around the world is increasing yet energy and natural resources which are nonrenewable, have continued to deplete. This scenario leads one to the many challenges faced by public transportation since it is directly linked to urbanization. From a civilian point of view, proper travel planning and knowledge of others' travel experiences are useful in easing public transportation woes. The authors apply Cyber Physical System (CPS) within cyber-physical-socio space to make those capabilities possible. In this approach, they regard data as a service, data are contributed and queried by the public masses. Location and time represent the physical domain and data with information derived from them represent the digital domain in their CPS design.
