As requested by the FHWA Offices of Safety Peer-to-Peer program, MTJ Roundabout Engineering assisted with the development of recommendations aimed at optimizing safety.
Working with FHWA and Caltrans, MTJ conducted a capacity analysis to determine if lane reductions were possible to optimize safety while still meeting operational objectives.
This work effort involved a comparison of Rodel’s capacity prediction to recently collected FHWA-measured capacity data. We found Rodel’s capacity predictions to correlate very closely with FHWA field collected data. This predictive confidence allowed for development of reduced laneage at entry and circulating, simplifying driver decisions, improving driver comprehension, and optimizing safety.
