Specifications include, but are not limited to: 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. The guidebook should: Identify the range of multimodal cross-sectional design elements, their potential context applications, their interactions, and their potential impacts on the transportation network. Present quantitative and qualitative measures that address multimodal performance of alternative roadway cross sections. Identify or develop methods for predicting outcomes such as mode shift, safety performance, and social, economic, and environmental consequences. Present mitigation strategies for addressing potential negative outcomes. Identify barriers to implementation and strategies to overcome the barriers. Present key messages and techniques to effectively communicate information on the benefits and trade-offs to stakeholders. Identify gaps in the state-of-the-practice knowledge that may be attributable to insufficient data and experience that may be addressed in future research.
