Currently the Traffic Calming Program contains ten holdover
neighborhoods and those new neighborhoods, which have petitioned for
program admission and successfully passed a traffic study of vehicles on
neighborhood streets, speed studies and accident records for the
neighborhood. All economic levels of the City are represented. Concerned
parents are the driving force behind the majority of neighborhood
mini-committees currently preparing traffic calming plans for their
Before & After Studies
To gauge the effectiveness of the traffic calming program and measure staff progress towards these areas of citizen concern, staff conducts “before and after” studies of all City neighborhoods which have been traffic calmed.
To date, seven neighborhoods have been reviewed for changes in traffic volumes and speed as a result of traffic calming efforts. The main focus of the program is speeding and the traffic calming program has resulted in an 18% average reduction in speeds on neighborhood streets. The data also shows a side benefit being a reduction in traffic volumes, with an average reduction of 27% in volume. Keeping speeds under 30 miles per hour in neighborhoods provides a significant reduction in crash and injury potential. The attached tables and graphs illustrate the average results for the neighborhoods studied so far.
