OVERTAKING LANES AS A COST - EFFECTIVE METHOD FOR RURAL HIGHWAY IMPROVEMENT

Overtaking lanes offer a potential for substantial improvements in the level of service on rural highways at relatively low cost. While capacity is not increased, significant benefits may be realized through reduced bunching, savings in travel time, and improved road safety. Overtaking lanes may therefore present an intermediate step for rural road improvement at a fraction of the cost of duplication. They merit particular attention due to the current shortage of road funds, and uncertainties about travel trends on some roads. Because only short lengths are constructed, it is possible to reduce costs by a careful selection of location. The factors of traffic flow, traffic composition and road sight distance variations must be considered in the design and evaluation of overtaking lanes. (TRRL)
