EXAMPLES OF SAFETY IMPROVEMENTS (OTHER THAN WIDENING TO FOUR LANES) FOR TWO-LANE RURAL ROADS

Many highway agencies regard the construction of a four-lane divided highway segment as the most desirable response to mitigate accidents and improve operational problems on two- and three-lane highways. However, such improvements are expensive, and the funds for upgrading rural roadways are often limited. As a result, constructing a new four-lane highway or widening an existing roadway may upgrade only a small portion of the network, while the other road sections continue to operate unsatisfactorily. As an alternative, lower-cost improvements on existing two- and three-lane rural roads can solve many operational problems while improving a much larger portion of roadways. Research and experience have shown that the provision of passing lanes, turning lanes, localized alignment improvements, signs and pavement markings, median treatments, public information and education, increased enforcement, and other relatively low-cost measures can be highly cost-effective in improving both traffic operations and safety on existing two- and three-lane rural roads. As part of a National Cooperative Research Program Project, examples of implemented improvements were identified. These examples illustrate the types of improvements that have actually been implemented by state and local highway agencies. This paper contains a summary of selected examples.
