DESIGN CRITERIA FOR APPLICATION OF LOW-SPEED WEIGH-IN-MOTION

The three basic components of an Illinois-designed WIM (weigh in motion) facility are described. This consists of deceleration length, signal zone, and deceleration and storage lengths. Desirable layouts are described, as well as signage. The implementation of the system is also desribed. It is noted that ramp arrangements that negate pedestrian/vehicle interaction are superior designs. Locations of scales and signals that permit a viewing time of 6 seconds at a controlled speed of 30 mph are desirable. The ramp alignment preceding the divergence should provide equal widening or favor the bypass lane with a tangent alignment. These and other recommendations are discussed.
