Intersection study task 3 report: development of the kinetic energy management model and safe intersection design principles

The Kinetic Energy Management Model (KEMM) was developed by MUARC as a conceptual model for defining and analysing the various factors influencing crash frequency and crash outcome severity. Five layers of “protection” are used to either prevent the crash (by deflecting energy) or mitigate its effects and limit the risk of serious injury to less than 10 per cent (by absorbing energy). The KEMM concept is integrated with the four major risk areas in the safe system: the human, the vehicle, the road and roadside, and system operation. In this study, the model was extended to analyse intersection crashes (model known as KEMM X) with the primary focus of better measuring the intrinsic safety of the intersection as a whole. The inner three layers of the KEMM-X, relating to the risk of serious injury or death, have been modelled mathematically to provide a tool for objectively quantifying the safety of individual conflicts within an intersection. Practical examples of risk reduction in each of the areas are provided. Principles for safe intersection designs were then defined through the use of the model and are described in some detail in the body of the report: The subsequent stage of the long-term study is to assess existing intersection layouts in relation to the KEMM-X principles, and where possible embody the defined principles in to new, safe system aligned intersection designs.
