Cyber-physical systems in smart transportation

Cyber-physical systems offer a new approach to the application of information technology to improve the performance of a transportation system. This paper focuses on transportation system processes and the information technology requirements for applying cyber-physical systems to on-road transport systems. Traffic flow simulation studies consisting of vehicles and roads were conducted in order to understand real world transportation system dynamics. The requirements of cyber-physical systems in transportation are introduced as the basis for smart transportation systems applications and their development. Therefore, the paper also focuses on modeling cyber-physical environments that provide fidelity, while the components of such systems increasingly combine physical and digital subsystems, as shown in the use case example.
