Roundabout

Workers put the finishing touches on a roundabout under construction along California Drive at the intersection of Lorton and Bellevue avenues.

Burlingame officials are hopeful the soon-to-be completed roundabout near downtown will make a confusing and dangerous intersection more safe and convenient for pedestrians and pedestrians.

Public Works Director Syed Murtuza said the new California Drive roundabout under construction at the intersection of Lorton and Bellevue avenues is expected to be finished next month.

Unbelievable that it takes almost a year to install a roundabout. I'd like to see two important bits of information on this article: What is the total cost of this change, and just how dangerous was the old intersection - how man serious accidents per year?

By reducing California Avenue to one slow lane southbound, this is already causing traffic delays, I think it's a valid question as to whether all of this is worth it.

Am so glad Burlingame "gets it" in regards to Vision Zero and moving away from the old, 20th Century metric of LOS (level of service...for cars over pedestrians & cyclists) and moving into the 21st Century metric of prioritizing pedestrians & Cyclists over cars

It took society over 100 years of architecture metrics designing cities with LOS for automotive and it will take decades to move into an VMT methodology

Most folks are still in an automotive 1st mindset and hoping they will make the change away from an automotive based society.

Tidbit of info...current road systems were invented for bicycles. Before that, walking, riding a horse, riding on a horse drawn buggy or trolley

Applaud Burlingame for their vision

PS...SB-743 mandates the move away from LOS based metrics and into a VMT based metric

PPS...this is a prime example of "Traffic Calming" road design. Incorporating a Circular and a Chicane to slow down traffic and make it safer for pedestrians and cyclists

People using the road make mistakes (like running stop signs and red lights), always have and always will. Crashes will always be with us, but they need not result in fatalities or serious injury.

Modern roundabouts are the safest form of intersection in the world - the intersection type with the lowest risk of fatal or serious injury crashes - (much more so than comparable signals). Modern roundabouts require a change in speed and alter the geometry of one of the most dangerous parts of the system - intersections.

The reduction in speed to about 20 mph and sideswipe geometry mean that, when a crash does happen at a modern roundabout, you usually need a tow truck, not an ambulance. Visit the Insurance Institute for Highway Safety for modern roundabout FAQs and safety facts. Roundabouts are one of several proven road safety features (FHWA).

Modern, slow and go, roundabout intersections have less daily delay than a stop light or stop sign, especially the other 20 hours a day people aren’t driving to or from work (it’s the #2 reason they’re built). Average daily delay at a signal is around 12 seconds per car. At a modern roundabout average daily delay is less than five seconds. Signals take an hour of demand and restrict it to a half hour, at best only half the traffic gets to go at any one time. 'At best' because traffic signals must have the yellow and all red portion (6+ seconds per cycle) for safety, and modern roundabouts do not. At a modern roundabout, drivers entering from different directions can all enter at the same time. Don’t try that with a signalized intersection.

Concerned

First of all, all City communications before the project started, and during its construction, said it would be completed in December 2018. Suggesting it is on schedule is simply not true.

Secondly, while having breakfast at Stack’s last week, I was troubled by how fast the traffic was flowing south through the new roundabout. With the driver visibility reduction emanating from the circular flow of traffic, pedestrian crossings will now be less safe across California Drive as traffic speed seems as fast as ever.
