Traffic Calming Study

Cribb Philbeck Weaver Group (CPWG) was selected to conduct a traffic calming study for the City of Longwood on the major roadways and provide recommendations to calm traffic is problem areas. The study focused principally on Grant Street, Wildmere Avenue, and Oxford Street. Other roadways identified in prior public outreach efforts were evaluated, but in lesser detail, to identify potential impacts from calming efforts on the major roadways.

CPWG Transportation experts collected all data previously collected by the city and established 24 hour traffic counts, recorded in 15 minute intervals, for each of the study roadways. Field inspections were conducted to inventory all pertinent roadway characteristics required to develop traffic calming plans, including roadway widths, posted speeds, and other roadway characteristics.

Our team used state and local regulations, as well as the Complete Streets policy, to assess the traffic flow. Potential traffic calming techniques were evaluated to determine if their use was appropriate and/or warranted given the traffic volumes, prevalent speeds, and roadway conditions. The team then focused on determining the suitability for application, potential effectiveness, and potential implementation cost of the traffic calming techniques for each of the subject roadways. These methods included signage, horizontal deflections, vertical deflections, and other traffic control devices, such as interactive speed warning (radar) signs.
