said the firm used a radar gun to take between 50 and 100 samples of driving speeds at each location.All of the samples were taken on a clear day when the roads were dry.If 85 percent of the drivers sampled drove within 5 mph of the limit, the posted speed is appropriate, Roth
That was the case at two locations - on Warrior Lane between Hickman and Ashworth and on University Avenue east of Waukee High School
- where Roth
recommended the speed limit remain 35 mph.Roth
recommended increasing the speed limits from 25 to 35 mph on University Avenue west of the high school.
On Laurel Street, between Warrior Lane and Fourth Street, Roth
recommended raising the speed limit from 25 to 30 mph.
said the final two areas required further discussion.
On Alice's Road north of Hickman, 85 percent of motorists were clocked driving 11 mph faster than the posted limit of 35 mph.Roth
said the council could consider increasing the speed limit there to 40 mph.
said the council could leave that speed limit as is or could bump it to 30 mph and post warning signs.
