Development of Temporary Rumble Strip Specifications, Technical Summary.

摘要

A detailed literature review, a survey of practice, and a closed-course test were performed regarding temporary rumble strips. Additionally, data from permanent cut-in-place (CIP) rumble strips at six locations in Kansas were collected. All commercially available portable reusable temporary rumble strips were tested at once in a closed-course setting using a standard dump truck and a full-size car. The rumble strips’ rotational movement, linear movement, and sound produced by a traversing vehicle were chosen as parameters in developing the decision matrix. Measurements of the strips’ linear and angular movements and sound generated due to the test vehicles passing over the rumble strips were collected for a total of 40 passes each at speeds of 22.5, 37.5, 57.5, and 67.5 mph. Threshold limits for movements, rotation, and sound generation of the temporary rumble strips at each of the speeds were calculated for developing the classification table. Annual Average Daily Traffic (AADT) and Average Daily Truck Traffic (ADTT) were used in calculating threshold limits for movement and rotation, and sound threshold limits were based on CIP strips’ sound data. A matrix and a classification table were created with class intervals defining the classes based on the performance of temporary rumble strips at each of the speeds.
