However, when they pass through small towns the speed limit is reduced to 30mph or lower. Drivers traveling through farm lands along rural roads tend to travel at high speeds.<span style="mso-spacerun: yes">  </span>When drivers continue along the same road and pass through a small town they may not be prompted by the change of environment and continue at the same speed or, only minimally reduce their speed, which raises safety concerns in these areas. <span style="mso-spacerun: yes"> </span>Similar problems may occur in suburban areas with transitions from higher speed limits to lower speed limits in more densely developed areas.<span style="mso-spacerun: yes"> </span></font></font></span><span style="mso-bidi-font-style: italic; mso-bidi-font-weight: bold"><font size="3"><font face="Times New Roman">Existing traffic calming techniques have been successfully practiced across the world in the past years, especially in the <st1:country-region w:st="on">United States</st1:country-region> and <st1:place w:st="on">Europe</st1:place>, to reduce vehicle speed and traffic volume in residential or community areas. Limited research has been conducted on the subject so there is no existing toolbox on how to calm traffic speed on high speed rural roads. The concepts, system designs, and useful measures, and the state-of-practices need to be documented to help enforce vehicle speed on high speed rural and other roads.<span style="mso-spacerun: yes">  </span>Doing this could help save lives and improve safety in small towns. </font></font></span></p>
