Guidebook for Urban and Suburban Roadway Cross-Sectional Reallocation

项目名称：	Guidebook for Urban and Suburban Roadway Cross-Sectional Reallocation
摘要：	The allocation of space within a roadway cross-section allows for the movement of people and freight. Designs for urban and suburban roadways should balance operational and safety performance among multiple transportation modes, while meeting a variety of societal goals such as social equity, economic vitality, public health, and environmental stewardship. Design guidance exists for individual elements within a roadway, such as travel lanes, on-street parking, medians, and bicycle, pedestrian, and transit facilities. However, current design guidance does not reflect the complex and varied trade-offs transportation professionals consider for existing roadways in different contexts. Less research has been done on the benefits of other configurations for roadway space reallocation. Since there are positive and negative effects associated with different roadway configurations, designers should consider the potential outcomes for all users and assess trade-offs. However, there is limited context-based guidance available to practitioners on how to evaluate trade-offs in cross-sectional reallocation of existing urban and suburban roadway space. The objective of this research is to develop a guidebook and decision-making framework for roadway designers, planners, and others for identifying, comparing, evaluating, and justifying context-based cross-sectional reallocations of existing urban and suburban roadway space for multimodal safety, access, and mobility.
