摘要：	For a number of years there has been a controversy regarding whether installing roundabouts in a business area are good for business in the area, or whether they have negative impacts on business in the area. This study attempts to answer this question with emphasis on Kansas cities, particularly Topeka, Kansas; however, it does use examples and data from other cities and studies that are relevant to this study. This study reviewed the literature and all sources where national data or reliable case studies addressed the issue of the impact of roundabouts on business to serve as a basis for Kansas studies. Some data that was initially thought to be available; namely, business profits, before and after economic data like sales taxes, property values, building permits and so forth, were not generally available and/or beyond the scope of the project. The study concentrated on the literature, surveys to businesses, and case studies that showed roundabouts ability to move traffic more efficiently. Conclusions were based on the widely accepted assumption that businesses and business areas that have good vehicle and pedestrian access and traffic flow should prosper and grow and, conversely, businesses that do not have good access and good traffic flow will not. Case studies that were found in the literature, and from personal contacts, are reported in the study report. Surveys were conducted and sent to several Kansas cities as well as Carmel, Indiana, which is known to have a great number of roundabouts in the city. Personal contact was also made with a number of business managers and/or owners in Topeka. Since no reliable before and after corridor data could be found that would lead to definite conclusions, a task was added to do a simulation study of a business corridor in Topeka, Kansas. The study used VISSIM software to simulate a hypothetical before and after study of converting several traditional intersections in the corridor to roundabouts.
