I would love to see more roundabouts and hope the idea is adopted more, but I am not so sure how it would work on high volume intersections.

I think a roundabout on Wilderness Oak/Hardy Oak would be perfect for the amount of traffic going through there, but instead they are soon installing another stupid traffic light.

I just thought I'd let everyone know that I am following this thread, and so are others .....

Unfortunately, I don't see a way to register and respond to the aforementioned post, but I wanted ya'll to know - I am following this thread. ;-)

In response to that post though, am I reading that right?

Texans are too dumb for roundabouts?

Wow.

I've lived in France. In France, congested intersections FLOW. Give a Frenchman a cell phone, a red light, and you know what you have? Lunch! (God forbid he has an F350 and an iPad!) If the French can figure out roundabouts - SURELY Texans can.

A few thoughts: In roundabouts drivers have to maintain their awareness throughout the entire intersection... BECAUSE THEY HAVE TO. It is a fact that there are lot less serious and fatal accidents in modern roundabouts than traffic controlled boondoggles like Culebra and 1604.

Our current traffic controlled intersections allow people to sit, park, read, call, brush, pick and light. They have sensors, that (in theory) keep the traffic flowing. But these sensors are OFTEN times trumped by inattentive drivers... and perform mediocre at best in the best of conditions.

In a roundabout - you are already assuming someone is coming from your left and is going to plow into yo azz. Roundabouts breed caution. They are magical when they work right. :-)

Current traffic controlled intersections are complicated, expensive, inefficient, non-sustainable, prone to serious accidents, environmentally unfriendly, and wasteful.

Roundabouts are cheap simple and smart.

Just yesterday, I was on 1604 S and taking a left (E) onto Potranco. (an unusual route for me). I was stopped waiting for my left turn light. A concrete truck - I am not kidding - 12 tons of crap - comes whizzing inches past right door, at at least 70 miles an hour, trying to make the green light on 1604 southbound. That wasn't an accident on that day, but there will be one just like it in the near future, I guarantee it. THAT nonsense, does not happen in roundabouts! PERIOD.

Roundabouts are inherently more efficient and WAY safer. IMHO. Slow all traffic to 40, and let us figure it out.

I think the roundabouts on private roads inside shopping complexes seem to work reasonably well. The only one I've experienced on a public street in San Antonio (actually, City of Olmos Park) is at McCullough and Olmos, and that one is a total failure, IMO. The thru traffic on McCullough likes to blow through it without yielding, making it dangerous for motorists approaching from the two other streets. And they finally gave up rebuilding the fountain in the middle of the circle that kept getting plowed down by motorists that would blow through the intersection.

I will go out of my way now to avoid that roundabout.

We say almost every day we wish more intersections had roundabouts! They are easy to use.

Roundabouts are not common here in San Antonio. People here are not used to them. You take that as "Texans being too dumb" to use them. Whenever you are exposed to a new process that you never learned before, do you master it the first time?

Disagreement here that Texans, even SAers more specifically, could not learn how to properly maneuver through a roundabout. The reason we lack them is due to traffic engineers and administrators deciding not to install them.

There are also other measures which would increase safety and decrease traffic accidents saving both lives and money for all of us.

Click the link to read the article in full. Eric Dumbaugh from TAMU's Urban Planning Department appears in it.

Quote:
A Danish city redesigned a major intersection, adding a traffic circle and fountains, narrowing roads, and reducing signs and signals. The result? Injuries at the spot have fallen from eight per year to just one.

Meanwhile, the United States has been slow to embrace the "white-knuckle" approach. American traffic design centers on improving traffic flow, which often means creating roads that cars can zoom through effortlessly, Dumbaugh says.

I'd never even heard of roundabouts until I was in Australia. I took a bus from Brisbane to Queensland and I was woozy after all those roundabouts. Traffic seems to flow nicely, but you'd have to get used to them....of course they also drive on the left side of the road so I was even more confused! They would work here once everyone learned how to use them so that traffic flowed easily.

Perhaps adding in a speed bump temporarily for north-south traffic could serve as a learning curve in teaching others to slow down before approaching?

More permanent elements could be breaking up the flow of traffic on McCullough by engineering in curves on the road before the roundabout, public art along the thoroughfare, and other distractions so drivers on the busier street come in slower than now.

How many accidents have there been at that roundabout in Olmos Park? (and if any - any injuries?) - just curious.

I will take a drive through it tomorrow. :-)

Plenty of single-vehicle accidents and most likely involving alcohol.

Don't forget about driving through the lesser used Alameda Circle as well if you want to visit both of our areas roundabouts.
