Recent Testimonials
“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.”
Rob Day / RTA (NSW)
“I have found SIDRA to be a valuable tool to assist in traffic analysis; the model is able to reflect existing operating site conditions accurately and this in turn gives confidence in the SIDRA predictions for future traffic scenarios when assessing project proposals. The professional support from the SIDRA Team adds value to a user friendly product.”
Terry KEATING / TPK & ASSOCIATES PTY LTD
“I have found SIDRA to be very useful in my line of work, always learning new way to do things.”
Daniel Telford / O'Donnell QLD Dept of Transport and Main Roads
“I use SIDRA 4 signal phasing, so that I can use that data as input for my DYNAMEQ microsimulation software. The DYNAMEQ software is designed to look at area-wide traffic flows together with measures of congestion, such as lane and node occupancy. I use the SIDRA phasing data as inputs when I test alternative scenarios.”
Paul van den Bos / Transport Modelling
“I was introduced to SIDRA in 2001 and attended the Sept 2002 SIDRA 2.1 course in Auckland. In the last 6 months I have used the modelling software approx 10 hours/week. I find it an extremely effective in analysing alternatives and use the capacity and performance characteristics such as delay, queue lengths in economic roading studies. (You still have to carry out on-site queue length and delay studies to calibrate the model.)”
Tom Thompson / Opus Consultants
“Having taught them the theory, we use SIDRA to introduce students to practical aspects of trying out different intersection configurations. As well as being the industry standard in this part of the world for isolated intersection analysis, SIDRA is very straightforward for students to get the hang of. This makes it a logical choice as a teaching tool.”
Dr Glen Koorey / University of Canterbury
“Sidra is a wonderful tool for assessing individual intersections”
Edmond Platon / RTA
“When our agency was tasked to perform a benefit/cost analysis for nearly twenty projects within a months’ time, we did not know of any software that could help us. When we were informed of SIDRA software and how it could be applied to our tasks, we immediately used the available trial version, and completed our tasks within a three-week timeframe. I'm sold on the software, and I'm encouraging the North Carolina Department of Transportation to partner with the other metropolitan planning organizations throughout the state to purchase SIDRA under one contract to allow statewide usage.”
