Traffic Signal Design and Operations Strategies for Non-Motorized Users

The objectives of this research are to (1) identify and evaluate a broad range of current international and national practices for signal design and operations strategies for non-motorized users including vulnerable road users with disabilities; (2) identify gaps in the state of practice on signalized intersections with multimodal specific infrastructure and intersections with varied geometric designs (e.g., signalized path crossings, diverging diamond interchanges, continuous flow intersections, etc.); (3) develop guidance for traffic signal design and operations strategies that will address the needs of non-motorized users and increase their respective multimodal connectivity; (4) develop a means to convey how to best incorporate findings to a wide range of stakeholders including those with visual impairments and other disabilities; (5) recommend germane language for inclusion in future updates to guidance documents (e.g., the AASHTO design manual, the Traffic Signal Timing Manual and specifications); and (6) identify opportunities for future research.
