Speed Studies

This dataset contains the results of traffic engineering studies conducted on streets in Norfolk. Residents can apply for a speed hump or speed table to be installed via MyNorfolk. Upon receipt of the request, the Department of Transportation schedules a traffic engineering study to determine the level of speeding and traffic volume. If the prevailing 85th percentile speed is at least 8 miles per hour above the posted speed limit, then a street segment qualifies for a speed hump if the traffic volume is between 500-3,000 vehicles per day, or a speed table if the volume is between 1,000-4,000 vehicles per day. These qualifiers do not guarantee a speed hump/table but are the initial qualifiers to move forward in the process. There are several more steps required to complete the process of installing a speed hump or speed table in Norfolk after the traffic engineering study is completed.

This dataset the includes the location of traffic engineering studies, study start and end dates, traffic volume, vehicle class and axel volume, average and percentile speeds observed, and the number of vehicles traveling above the speed limit. The dataset will be updated ad-hoc as new speed studies are conducted and the results are provided.
