Simulating the Impact of Traffic Calming Strategies

Many communities in the United States are using traffic calming as a means to control safety in their neighborhoods. Traffic calming can range from speed humps and traffic circles to a reduction in the number of lanes as a reactive response to the traffic and speed complaints for some residents. Other well-known traffic calming may also include raised median island, traffic circle, raised crosswalk, crosswalk refuge, road diet, choker, and chicane. Although each traffic calming strategy may be different, there are certain aspects that are crucial in the overall livability of the communities. Operations of emergency vehicles is one of the issues which can be affected by traffic calming practices. While solving many problems for local residents, many types of traffic calming measures can create problems for emergency response vehicles. The designs that create diversions or obstacles and create lower average speeds for the everyday drivers, also forces the drivers of emergency response vehicles to slow down. This study will therefore use microsimulation through VISSIM and VISUM to assess the influence of traffic calming measures on speeds, travel times, route choices, model split on the level of traffic operations, road safety, and air pollution. The influence of individual traffic calming measures will be examined at a microscopic level to quantify their impact of each of the measures and their impacts to the livability of the communities.
