Effectiveness of Speed Minders in Reducing Driving Speeds on Rural Highways in Pennsylvania

2008

The objective of this project was to determine the effectiveness of dynamic speed display signs (also known as "speed minders") in reducing vehicle operating speeds. The Pennsylvania Department of Transportation (PennDOT) has invested in several speed minders. Each engineering district uses the speed minders in an effort to assist in managing vehicle speeds, particularly in locations where the roadway transitions from a high-speed (45 to 55 mph) to low-speed (25 to 35 mph) operating environment. It is common for these regulatory speed limit changes to occur along roadways that pass through rural communities. PennDOT selected several locations in central Pennsylvania to position the speed minder signs to evaluate their effectiveness. These locations were primarily along roadways that transition from high-speed to low-speed operations on rural highways; however, several locations were on roadways without regulatory speed changes. Because each engineering district has only a ...

The Effectiveness of Regulatory School Flashers in Reducing Vehicle Speeds

1979

Pedestrian safety for school-age children has been a growing problem in recent years. Children between the ages of five and nine represent less than 10 percent of Kentucky's population but over 16 percent of all pedestrian fatalities. A study was conducted to evaluate the effectiveness of regulatory school flashers used in school zones to reduce vehicle speeds and alert motorists of pedestrian activity and to determine measures which promote safety in school zones. Speed studies were conducted during flashing and non-flashing periods at 48 school zones where regulatory school flashers were used. The locations involved a variety of speed limits (15.6 to 24.6 m/s (35 to 55 mph)), highway types (two-lane and four-lane roads), location types (rural areas, towns, and large cities), and pedestrian and traffic volumes. Average speed reduction during flashing periods was only 1.6 m/s (3.6 mph); 71 percent of the locations showed speed reductions less than 1.8 m/s (4 mph). Only two locat...
