Besides people shooting themselves over a meth deal in Sioux Falls these days, we have another epidemic, speeding in residential areas. If I hear one complaint more from residents about crime, it is people who speed through sensitive areas (mostly school zones). There is a solution, and it is quite effective, and rather inexpensive. Small towns across South Dakota have been using solar powered flashing speed signs. Not only are they pretty frickin’ handy, they can also be moved quite easily using a bracket system.
Councilor Stehly is pushing for ‘testing’ these signs. She was voted down during the budget process, but she tells me that she is still pushing for them. Like snow gates, Theresa won’t give up until they are implemented or at least tested.
Our chief traffic engineer responded to a series of questions from Theresa;

Subject: Responses to Speed Trailer Questions
1. You indicated that we are using the speed safety signs on poles within school districts only. The city currently does not own any for residential areas.
That is correct, so far we have limited usage to School Zones.
 2. We talked about the areas that are high complaint areas. Right now, how often do we put the speed trailers out. How many speed trailers do we have and how long do you let them sit in an area? How do you decided who gets to have the speed trailers?
There are three speed trailers that are moved around to different locations on a weekly basis from Spring thru Fall. A list of speeding complaint areas that is generated by calls to Police, Public Works, City Clerks, Mayors Office and received CRM’s is used to determine where the trailers are placed.
 3. We talked about the speed trailers we currently have sticking into the roadway. It is also my understanding that they are bulky and labor intensive to move.
Depending on location on narrower streets the trailers can influence traffic quite a bit due to protruding into the driving area (this can be good and bad).  The trailers generally take up a parking spot in order to be placed so they are not able to be placed at locations that do not have parking. It takes approximately one day for a person to pick-up and deploy the three speed trailers that the City currently has.
 4. You seemed to view the addition of pole mounted solar speed signs in notorious complaint areas as a possible benefit for our community. You said you would appreciate it and they would be used  if they were available.
That is correct. We have explored the concept of what you are proposing a couple of years ago and our biggest concern was what the expectation would be for relocation timelines. The 3 month rotations that you were talking about would be reasonable to work with.
 Please let me know if you need anything else.
