Practices for Adding Bicycle and Pedestrians Access on Existing Vehicle Bridges

项目名称：	Practices for Adding Bicycle and Pedestrians Access on Existing Vehicle Bridges
摘要：	State departments of transportation (DOTs) have created plans for improving or expanding existing bicycle/pedestrian networks to increase active transportation options along their state owned roadways. Expanding these networks on roadways might be accomplished by reallocating roadway space and dedicating bicycle lanes or by constructing new sidewalks or cycle tracks to safely accommodate pedestrians and bicycle riders. However, since many vehicle bridges were not originally designed for pedestrians or bicycles (e.g., no sidewalks or shoulders), they represent one source of gaps in existing and potential bicycle and pedestrian networks. Closing these gaps across an existing vehicle bridge is a common problem for state DOTs with no "one size fits all" solution. The objective of this synthesis is to document the practices employed by state DOTs to provide or improve access to existing bridges for active transportation users. The synthesis will only focus on existing bridges and not on new construction. Information to be gathered includes (but is not limited to): (1)Techniques that state DOTs have used, are using, or have considered using to improve access to existing bridges (e.g., dedicated bicycle lanes, shared bicycle/vehicle lanes, sidewalk extensions, new sidewalks, cantilevered sidewalks, dedicated bridges, or other treatments); (2) Characteristics of the bridges where access has been added (e.g., superstructure, original lane layout, average daily traffic, or another unique charateristic that enabled success); and (3) Case examples for a select number of completed projects or projects in construction. Information will be gathered through a literature review, a survey of state DOTs, and follow-up interviews with selected agencies for the development of case examples. Information gaps and suggestions for research to address those gaps will be identified.
