| 摘要： | The objectives of the research were: (1) to obtain updated information on DOTs' policies and guidelines for installation of centerline rumble strips (CLRS) in the United States in order to identify current practices; (2) to verify the before-and-after safety effectiveness of CLRS currently installed in Kansas; (3) to determine if CLRS cause levels of exterior noise that can disturb nearby residents and propose a minimum distance from houses for installation of CLRS in Kansas; (4) to estimate the effects of CLRS on vehicles' operational speed and lateral position and to verify it if is safe to install CLRS on sections on highways with narrow shoulders; and (5) provide recommendations of when it is beneficial to install rumble strips, given known values of traffic volume, shoulder width, and the presence of other types of rumble strips. |
