Changes coming for I35/Hwy 30 exit

[BikeSkiClone]

The problem I have with them is when they are put in places that don't need them. My friend has one by his house that people go backwards on it because there is never more than one car and it makes no sense to go 3/4 of the way around. The ones by Johnston High School are similar. There was no need for them and they just slow traffic down.

I would think roundabouts would most benefit those who need to turn left (as in, those who would go 'backward' on the roundabout). Is it really worth the risk to drive the wrong way and save less than 5 seconds?

A quick glance at Google Maps shows a series of roundabouts in Johnston around Pioneer, which I assume are the ones you're talking about near the HS. Is it not a little more efficient for people leaving Pioneer and the complex to the north who need to make left turns and people making right turns? Both can be done at the same time and few people have to come to a full stop and nobody has to wait for a light cycle.

The ones in Johnston were most definitely necessary. It was either a roundabout or a stop light.

I do agree on the other points, and hate when roundabouts are used in low traffic areas where a stop sign is more cost effective.

I don't know about when people get off work, but that is the only time they would be needed. I have never or rarely see people do anything but go straight.

Okay. So one example of a very specific situation means decades of research is wrong?

I think you are confusing traffic within a metro area, such as I-235, and traffic between cities like I-35 between Ames and Ankeny.

Stop sign easily when people aren't there. The ones in Johnston need to go back to two way top signs.

Obviously you're one of those special people who think that the bright red octagon-shaped sign reads "PAUSE."

isn't the point of the question that it makes so sense - either in time or gas consumption - to sit and wait at an intersection where no one is coming. not that people are above the law but that having stop signs as the default for rural intersections is not ideal

If you can't manage a roundabout you should have your license revoked. They're easy to navigate and better than waiting endlessly at lights or stop signs. In the Detroit metro we even have them when turning off onto a surface road from a highway exit.

They built roundabouts in Saudi Arabia and many died. Of course, they never had drivers training. In that country they left disabled MercedesB on side of road and bought a new one.

So you're saying the problem needs to be fixed before the problem exists? Have you lived in the United States before? .

do you wait for a heart attack before you start exercising?

the current way of cities' regulating land use absolutely causes traffic issues. it obviously won't fix what's built today but that doesn't mean we can't make changes starting now.

In SimCity, I just demolish whole neighborhoods and start over. Let's do that!
