Roundabouts are perhaps something that should be considered for Philippine roads. The concern, however, is that Philippine drivers don’t know how to navigate or position themselves in roundabouts. And the results as we have seen in several cases are congested roundabouts or rotundas.

AASHTO (September 26, 2025) “State DOTs Highlight How Roundabouts Improve Safety,” AASHTO Journal, https://aashtojournal.transportation.org/state-dots-highlight-how-roundabouts-improve-safety/%5BLast accessed: 10/19/2025]

To quote from the article:

“To highlight the safety benefits of roundabouts, the Ohio Department of Transportation recently released an analysis of crash data from 76 intersections statewide that had been converted to roundabouts. That analysis indicated single lane roundabouts decreased injury crashes by 69 percent while multi-lane roundabouts resulted in a 25 percent decline.”

And here another quotable from the same article:

“For us, it’s simple. Roundabouts remove cross-traffic turns and eliminate T-bone crashes, while improving traffic flow,” said PennDOT Secretary Mike Carroll …”“Any design that dramatically reduces the most serious crashes we see on the road is worthy of consideration in our projects.”

The article also includes a YouTube video on traffic circles.
