In response to community concerns on two parallel streets that lead between city arterial roads, the City of Rochester installed speed humps in 2000. A follow-up study, performed in 2001, demonstrated that the speed humps were effective in reducing traffic volumes on diversion routes. Peak hour traffic counts revealed that traffic on Winchester Street decreased by 15 percent to 21 percent, while traffic on Merrill Street decreased by 23 percent to 27 percent. City of Rochester data revealed the percent of vehicles over the speed limit of 30 miles per hour was 61 per cent before installation of the speed humps and 15 per cent after. Survey results clearly revealed the role of perception in the evaluation of traffic calming. While many residents rated the speed humps as highly effective in reducing speed, just as many felt that they had no effect at all. It appears that for some people, speed reduction is not as important as personal inconvenience. (Author/publisher) For the covering entry of this conference, please see ITRD abstract no. E213531.
