Abstract

Initial results are presented of a comprehensive experiment dealing with speed control in a rural school zone on a high-speed, two-lane highway. Data were collected in a school zone located on the Maine Facility, an electronically instrumented roadway where a 15-mph (24-km/h) speed limit is in effect during certain times of the school day. The experiment was to determine the effects on drivers of the Manual on Uniform Traffic Control Devices mandatory and advisory school zone signs, including beacon flashers, and and the effect of a new, dynamic speed violation sign. Speeds for automobiles and large vehicles were measured for one dynamic and four passive sign conditions when the 15-mph (24-km/h) speed limit both was and was not in effect. No enforcement was used during the experiment.

RESULTS showed that (a) vehicle velocities at the school were less when the driver was advised by flashing beacons that the 15-mph (24-km/h) speed limit was in effect, (b_ the average vehicle velocity was relatively constant at the school when the speed limit was not in effect, and (c) the lowest average speeds at the school 34 mph (55km/h) were obtained when the dynamic speed violation sign was used.
