Title

Dynamic Speed Monitoring On Sharp Curves Utilizing A Wireless Solar-Powered Dynamic Speed Monitoring System

Abstract

A solar-powered, radar-based, dynamic wireless speed monitoring system was implemented at a trumpet interchange on the border of Polk and Lake Counties, Florida. DSM, sometimes called speed monitoring displays (SMDs), is a technology available to transportation engineers to reduce speeding on highways. Speed data were collected via the DSM system radar as vehicles approached the sign, as well as at the point of curve (PC) of the study ramp, using pneumatic tubes. Fourteen days of 24-hour approach speed data and 7 days of 24-hour PC speed data were collected directly before and directly after the DSM system installation. The raw data were compiled into eight data sets. A simple before/after effectiveness evaluation was used since the study period was short and there was no reason to believe that there was any threat to the validity of the study. The DSM system was effective in reducing the proportion of vehicles in the high-speed ranges.
