Holistic consideration of intelligent transport systems is key to the delivery of modern transport systems. This view embraces the interfaces and interactions between modes and users that most often lie at the core of any safety issue—and these interactions, in great part, involve motorized vehicles.  

While the physical design of vehicles is outside the scope of the intelligent transport system (ITS) field of work, there are vehicle-focused technologies, either particular to the vehicle itself or as part of the broader data-led ITS whole-system approach, that have an impact on the overall safety of the transportation ecosystem. A holistic perspective of transport systems, based on the Safe System principle of shared responsibility among the road system users and system designers,1 will facilitate vehicle-safety improvements in line with Vision Zero, which seeks to prevent death and serious injury within the worldwide road transportation system.
