This paper illustrates how policies that relate to traffic calming devices are implemented in the Las Vegas Valley. Traffic calming is the attempt to achieve calm, safe, environmentally improved conditions on streets, and the lowering of speeds. Traffic calming measures reduce the negative effects of motor vehicle use, alter driver behavior and improve conditions for non-motorized street users. An analysis of The Nevada Revised Statutes was conducted to understand state directives pertaining to the implementation of policies at municipal levels of government. The study investigated how four governments (Las Vegas, North Las Vegas, Clark County, and Henderson) implement traffic calming measures in the Las Vegas Valley. The study consisted of personal interviews using a standard set of questions. Two of the governments have developed written policies. One of the governments claimed to have a policy, but it is not written, and the fourth claimed to not have a policy. The role of the Traffic Engineer in the problem identification, formulation, adoption, implementation, and evaluation stages of traffic calming are unique to each political setting. The study found different levels of support for the use of traffic calming measures within each government studied
