Access management techniques such as raised median installation and driveway consolidation improve safety conditions for motorists. Several locations where these access management techniques have been installed in the state of Utah were selected for analysis of the safety impacts. Although crash rates were not necessarily reduced as a result of the access management techniques, other safety improvements were observed. The raised medians generally reduced the more serious types of collisions, which resulted in a decrease in the severity of crashes. The fatality rates generally decreased as crashes became less severe. Because fatalities and the overall severity of crashes decreased, the overall cost of crashes was reduced. The cost of installing the raised medians was easily recouped by this reduction in the cost of crashes.
