== Abstract ==

​

Historically the methodology used to support road asset management in Ireland was analysis of collision data to highlight candidate locations for network improvements. Internationally, researchers have more recently looked at a correlation between collision rate and road design inconsistencies, which can be locations where drivers could be momentarily confused by unexpected changes in the road characteristics. As a result, there may be inconsistencies between the key variables of vehicle speed and available friction for the actual vs. the intended manoeuvre. Transport Infrastructure Ireland (TII) has initiated studies to develop a methodology for assessing these geometrically derived design inconsistencies on the road network. The major aim is to detect and evaluate locations on the network which exhibit such inconsistencies in a proactive method. The proposed technique relies on a risk-based approach, and is an evolution of research performed to date along with adoption of innovative technologies. The purpose is to generate a dimensionless multi-criteria model, which considers the main risk and geometric consistency criteria.
