This study examines policy/cost issues related to bicycle lanes, multi-purpose, and single use-paths based on an explicit process the American Association of State Highways and Transport Officials (AASHTO) and empirical analysis of several case studies. Research continues to identify criteria for the planning and design of appropriate bicycle facilities and pedestrian systems, but the selection and costs of these modes of transportation depend on many factors including planning organization, public support, funding, traffic type and characteristics, adjacent land use, expected growth patterns, terrain, path size and materials, and even the potential economic impact on and physical health measures of a community. Research on application of the three phase AASHTO process (planning, design/build, and maintenance) in cities and towns across the nation can yield cost-saving strategies based on experience and be made available to policy makers for increased productivity. |
