Functional classification system to aid contextual design

A proposed functional classification system has been developed to address context and multimodal accommodation of the existing classification system. The proposed functional classification system is intended to facilitate optimal geometric design solutions while accounting for context, user needs, and functions. The new classification system communicates improved information to the designer so that balanced designs can be achieved through documented prioritization of roadway users. The proposed functional classification system identifies user groups, which include drivers, pedestrians, and bicyclists. Fundamental design elements for each mode are identified, and design ranges for each are provided according to the overall roadway network type. The correlation results of context, roadway types, and users are displayed in the expanded functional classification system matrix, allowing for the development of a multimodal, context-based design with some degree of flexibility. Each matrix cell defines the various users (drivers, bicyclists, and pedestrians) and identifies those characteristics to be balanced.
