According to the US Transportation Research Board document "Roundabout Practices", SIDRA INTERSECTION is the most widely-used software tool in the USA for roundabout capacity and performance analysis, followed by Synchro and HCS, based on a survey of state transportation departments (based on 28 of the 37 state agencies responding to the survey question).
The report also states "To analyze roundabout performance, about three-quarters of the reporting states use some form of the Highway Capacity Manual 2010 model and SIDRA’s Standard Model; about one-quarter use some form of the United Kingdom equations. (Because states were allowed to select more than one operational performance model, there is some overlap.)"
The report "Roundabout Practice, A Synthesis of Highway Practice, National Cooperative Highway Research Program, NCHRP SYNTHESIS 488, TRB, Washington, D.C., 2016" can be downloaded from the National Academies Press (NAP) website.
"SIDRA INTERSECTION is a very powerful and useful tool for experienced traffic engineers. Its reputation is often tarnished when not used correctly, i.e. when a calibrated base model reflecting current observations is not created. It is user friendly for experienced traffic engineers, especially with reference to the detailed manuals provided. Unfortunately, in large organisations, SIDRA modelling is often assigned to graduates with little knowledge or experience on real life observations and traffic behaviour. The three 'C's to successfull modelling are "Calibrate" "Calibrate" and "Calibrate"."
David Wilkins / i3 consultants WA
"I have used SIDRA in USA, Asia and Australia for 20 years. It has continually improved and over the past six years I have found it extremely useful for analysis of roundabouts in California, Arizona, Oregon and Washington. It is quick and easy to use accurately and my clients respect the results."
Kevin Fehon / DKS Associates
"A great tool to enable students to undertake project work on live intersections as part of the academic syllabus"
Tom Mckune / Durban University of Technology
"I have been using SIDRA for the past 8 years and found all versions are intuitive and the output are very useful and concise for reporting."
Robert Kwok / Worley Parsons
"SIDRA is still our standard for roundabout analysis because of its solid basis in gap acceptance theory that has shown to be more reliable in the USA than empirical models based in other countries."
James Dunlop / NCDOT
"I have found SIDRA INTERSECTION to be a very reliable, versatile and effective tool for analysing intersection performance. The ability to calibrate the model to accurately represent existing intersection characteristics has been of significant benefit for both intersection design and future planning purposes."
