Article No. 5 in the six-part series addressing how intelligent transport systems can become part of the Vision Zero road safety solution. A link to the all the articles is provided at the end of this article.
Road transportation systems that work safely result from designs which safely manage the interdependencies and interfaces within them. When severe crashes occur, system designers must revisit the problematic points within the system, understand why and how they occurred, and review the system as a whole before taking corrective action with evidence-based measures. Understanding why and how severe crashes have happened is vital in preventing more deaths and serious injuries on roads—and thus integral to making zero deaths and serious injuries a reality.
With the Safe System approach, designers seek to resolve the issues everywhere within the system, not just at the locations where the crashes have occurred. This approach differs from improving “crash hot spots,” as it considers the road transport system holistically, looking at cause and effect in a system-wide context as a progression to achieve the goal of Vision Zero. Vision Zero is rooted in the position that death and serious injury are not acceptable consequences of mobility and strives to establish optimal safety for all users in road transport systems around the world.
