Development of a Decision Matrix and Specifications for Portable Temporary Rumble Strips for Short-Term Work Zones

The objective of this research was to develop specifications for portable temporary rumble strips (PTRSs) for their applications in different work zone settings. A decision matrix and a classification table were developed. Matrix parameters considered included rotational and linear movement, and sound generation of the temporary rumble strips. A closed-course test was performed regarding temporary rumble strips. Additionally, data from permanent cut-in-place (CIP) rumble strips at six locations in Kansas were collected. Threshold limits for linear and rotational movement, and sound generation of the PTRSs at each of four speeds were calculated for developing classification tables. Annual Average Daily Traffic (AADT) and Average Daily Truck Traffic (ADTT) were used in calculating threshold limits for movement and rotation. Sound threshold limits were based on permanent CIP strips’ sound data. This matrix consisted of all the classes (intervals), including various work zone conditions ranging from low-speed, low-volume to high-speed, high-volume conditions. This matrix in – combination with the classification tables provides – a basis for determining the applicability of PTRSs under different work zone roadway and traffic conditions.
