City workers installed nine radar signs in late November, with 24 more slated to be put up by the spring.
Randy Smith, Nichols Hills public works director, said the response from residents has been positive so far.
We have installed some near the parks and at the entrances to the city, he said. We haven't done any in the residential areas yet.
If a passing motorist exceeds the speed limit, which is 25 mph in most of the city and 20 mph near the parks, the sign will produce a strobe-light effect and flash the offending speed.
The signs cost about $3,000 apiece and were funded through general obligation bonds. Smith noted that the signs also collect traffic information that can be used to determine projected wear on the roads.
