Performance Evaluation of Chilean Roundabouts Based on FHWA "Roundabout: An Information Guide 2000"

This work presents an experimental application of the new Federal Highway Administration (FHWA) guide for roundabout design. The main objective of the study was to identify and evaluate a number of design problems associated with Chilean roundabouts based on the new FHWA guide. This was done by performing a complete diagnosis on existing Chilean urban roundabouts producing a list of the main operational and safety problems encountered. In addition, three existing roundabouts were modeled using aaSidra-2 computer program to evaluate its performance. Later the same roundabouts were redesigned using the new guide and again modeled with aaSidra-2. Based on this work it was possible to estimate the performance improvement of existing Chilean roundabouts if these were redesigned using the FHWA guide.
