Abstract

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.
