Creating Safe Road Ecosystems

This article—the last in a series examining how intelligent transport systems can become part of the Vision Zero road-safety solution—explores the contribution of the physical space to the safe design and use of road transport systems.

Phase 1 improvements have now been constructed, and since completion no serious injury or fatal crashes have occurred.12
