A recent trend in the automotive industry is the rapid inclusion of electronics, computers and controls that focus entirely on improved functionality and overall system robustness. This makes the automotive sector one of the richest targets for emerging innovations in Cyber-Physical Systems (CPS) . While this trend has affected all of the vehicle areas, there is a particular interest in active safety that effectively complements passive safety. Passive safety is focused on the structural integrity of the vehicle.

This position paper discusses limitations of the current automotive transportation active safety systems. A system approach can address all levels (the driver, the vehicle,and the traffic) of interconnection between machine, computer and human by leading to incorporating interactions and heterogeneity of different physical layers in a unified framework. The resulting analytical and computational infrastructure, with applications in crash avoidance and traffic flow management, is then discussed.
This position paper describes the challenge of ensuring run-time safety in cyber-physical systems.
The overarching problem is ensuring that computer-based systems will maintain safe operations even in the face of design-time and run-time faults. One way to address this problem is by creating an ability to perform run-time safety checks on CPS applications that can be used to record hazards, trigger emergency shutdowns (where doing so is safe), or perform other actions to minimize the consequences
