The intersection of two major streets can act as both a barrier and a node. Redesigning major intersections requires designers to critically evaluate the tools and trade-offs available to make an intersection work better for everyone.
While shorter cycle lengths, compact design, and pedestrian safety islands are all desirable components of a multi-modal intersection, the tradeoffs inherent in each make these difficult to achieve simultaneously. Weigh intersection geometry, signal timing, and traffic volumes to formulate a design that clarifies the hierarchy of street users, while enhancing the safety and legibility of the intersection.
Control speeds by tightly managing the design and spatial layout of intersections.
