I was wondering what the main intent of these are for? If I am allowed to approach the zone within the posted speed limit, then why notify me of my current speed?

Thanks
Paul

Paul,

The signs are there to make you aware of your speed as you are approaching the school zone when it is in effect. You are required to be going 20mph when you enter the zone. By having it here, we are attempting to get the attention of motorists and get them thinking about slowing down before they enter the zone rather slowing down after they enter the zone.

Our before and after speed studies have shown that the boards are getting people to slow down within the zone. We used to see just over 8 percent of motorists exceed the 20mph limit by 10mph or more. With the board in place, this percentage has decreased to less than 4 percent. We have also measured a reduction from 17 percent to 5 percent in the number of motorists who exceed the 20mph limit by 6mph or more when the boards are in place.

It would be nice to have the units placed throughout the zone, but from an economic standpoint it makes the most sense to install them with an existing school zone flasher where we already have a power source. By using our existing flasher locations we can easily relocate the radar boards every four to six weeks. If we were to install them in the middle of the zone, it would cost an additional $2500 for the pole, foundation, and solar panels needed to run one unit.

How can I request one of these or suggest a location for one? Twin Falls is the main road into our subdivision and also happens to lead to two schoools. There is a school zone toward the south end of the street nearer the schools but the speeding on this street is out of control - this should be our neighborhood first and a "through" street second. Can we get one of these "your speed is" signs installed on Twin Falls?

Holly,

We currently own three of these signs. They are rotated around the city and used in school zone areas. Since we do not own a large number of them, we usually only install them on major arterials where we have mid-block crossings (crossings without a signal or stop sign).

It is possible as we acquire more of these signs, we may install one on Twin Falls near Pioneer. I would not install one near Angel Falls and Twin Falls since vehicles already must slow down for the all-way stop where the children cross.

The fiscal year 2004 budget does have funding for the purchase of two more of these units (about $4,000 each). Through cost sharing with FISD, we may be able to purchase one or two more units in addition to the two approved.

To make a request for the signs, please e-mail me with the location. As we get more of the radar units, we do expect to install them in school zones that are on residential streets.

Thanks
