Criteria for Traffic Calming Measures

August 19, 2009

The Traffic Engineer for the City of Lakeland [David Uria] has undertaken a survey of Florida municipalities to determine the criteria in use to justify traffic calming meaures. A copy of the results summary is attached.

It’s interesting that they’re generally based on a combination of traffic volume and speeding. There’s general use of a criteria of 85 percentile speeds in the range 5 – 10 mph above the posted speed limits. Traffic volumes vary widely.

The table would be a good starting point for someone drafting traffic calming criteria.
