Context-specific design is integral to the ITS whole-system approach and crucial for the creation of safe road ecosystems to achieve Vision Zero, which seeks to eliminate death and serious injury from road transport systems around the world. Safe road systems underpin mobility and are essential to the development of communities where people can and want to live, work, learn, socialize and thrive.
1 System designers – according to the Vision Zero approach - include policymakers, politicians/government officials, infrastructure owners and operators, planners, engineers and road designers, vehicle manufacturers, trauma and hospital care providers, enforcers, plus any others who provide for the road transport system. Each contributes important knowledge and expertise to help make and keep roads safe.
2 While vulnerability exists in relation to all road users, Vision Zero characterizes “vulnerable” users as those most at risk in traffic, as they do not have an outside shield to protect them from the force of impact in a crash.

4 This assessment framework is explored in the article “On the ‘ITS’ Road Toward Vision Zero,” wsp.com. It explains how the hazards are identified within each environment and assessed objectively to inform the design toward achieving Vision Zero.
