Abstract：

Roadway　rumble　strips　are　used　to　reduce　driving　comfort　and　make　drivers　decelerate.　While　vehicle　suspension　systems　are　designed　for　passengers＇　comfort　by　absorbing　vibrations　caused　by　bumping　roadway　surface,　roadway　rumble　strips　are　implemented　to　alert　motorists　to　reduce　speed.　An　efficient　and　safe　roadway　rumble　strips　design　depends　on　the　understanding　of　the　vehicles＇　suspension　system.　Newer　marked　vehicles　always　have　better　suspension　system　that　can　absorb　higher　vibrations.　This　paper　investigates　the　relationship　between　vehicle　suspension　system　and　roadway　rumble　strips　design　through　TruckSim,　a　computer　simulation　model　for　trucks.　The　study　analyzes　the　various　shock-absorbing　effect　of　current　popular　vehicle　suspension　systems　on　the　roadway　rumble　strips　designs　in　order　to　evaluate　roadway　rumble　strips　effectiveness　in　speed　reduction.　©　2010　ASCE.
