Title
Annual Survey of Traffic Calming Projects Constructed in 2009
Memorandum
It has been about a year since the Maplewood Avenue, Devonshire Road, Gladstone Avenue, and Jewett Avenue traffic calming projects have been completed. After the review of the post construction traffic analysis and the feedback from the affected residents, we have concluded that the Traffic Calming program has been successful in meeting both objectives of reducing the speeds on the respective residential streets and in receiving the public’s approval.
The Maplewood Avenue Traffic Calming project, between Packard and Oakwood, included three speed humps and one raised intersection. The Devonshire Road Traffic Calming project, between Londonderry and Arlington, included two speed humps. The Gladstone Avenue Traffic Calming project, between Packard and Independence, included one raised intersection. The Jewett Avenue Traffic Calming project, between Packard to S. Industrial, included four speed humps and one raised intersection.
In June 2010, approximately one year after the installation of the traffic calming devices on the above streets, we conducted the follow-up traffic studies. The results indicate speed reductions of 6 to 9 mph, to levels below the anticipated 30 mph (25 mph speed limit + 5 mph) as shown in the following table:
Project Area Speed Before Speed After
Maplewood Avenue (Packard to Oakwood) 30 mph 22 mph
Devonshire Road (Londonderry to Arlington) 31 mph 25 mph
Gladstone Avenue (Packard to Independence) 31 mph 25 mph
Jewett Avenue (Packard to S Industrial) 31 mph 22 mph
In addition to the speed study above, we surveyed the residents in the projects’ area to learn about the residents’ level of satisfaction with the traffic calming improvements. The survey post cards asked if the residents were satisfied with the traffic calming devices installed on their street, and provided space for comment.
The survey cards were mailed to the affected residents...
