The City of Milwaukee had already taken speed reduction steps. In fact, Bradley Road recently underwent a road diet reconstruction project. During this project, a dedicated center turn lane was added.
Additionally, at no cost to the city, the Milwaukee Reckless Driving Taskforce worked with locally-based TAPCO to deploy a FAST-18T Speed Radar Trailer with data collection to capture the impact of traffic calming in the area.
The FAST-18T Radar Speed Trailer is a mobile speed trailer. And for this study, the FAST-18T was set up with TAPCO’s Five Stage Escalating Alerts, which were developed to increase the effectiveness of the FAST line, including speed radar trailers. The five stages of the alerts displayed on the radar feedback sign are 1) the vehicle’s speed 2) flashing of the vehicle’s speed 3) a “SLOW DOWN” message 4) red and blue alternating flashing bars and 5) a total blank out of the screen.
The Five Stage Escalating Alerts were tested by TAPCO innovators to prove order of effectiveness on drivers exceeding speed limits. However, the FAST line is equipped with these five alerts that can be programmed in any order and triggered by customizable speeds.
For this study, the FAST-18T was programmed to display a vehicle’s speed beginning at 25 mph for stage one. Once a vehicle’s speed was detected at 36 mph, the speed display began to flash for stage two. At 41 mph, a red “SLOW DOWN” message was displayed to oncoming vehicles for stage three. Then, for stage four, at 45 mph, red and blue alternating flashing bars appeared. And for the stage five, the trailer display would turn off if speeds above 55 mph were detected. This warning message sequencing is used to dissuade vehicle acceleration during different phases of speeding.
