Effectiveness of Bicycle Signals for Improving Safety and Multimodal Mobility at Urban Intersections

With increase of the non-motorized transportation users, more people are concerned about the non-motorized safety. Statistics shows that the majority of pedestrian and bicycle crashes occur at intersections on urban streets. For bicycle crashes, failing to yield/disregarding traffic control was identified as one of the main causes of bicycle crashes in Michigan. As a countermeasure to address such issues, more attention is paid to bicycle traffic signals at urban intersections. At the same time, there are needs for optimizing signal timing not solely for vehicular traffic but also for pedestrian and bicyclists, especially when bicycle signals are available. This research aims to investigate effects of bicycle signals at urban intersections on both safety and multimodal system efficiency. The bike signal system will be further investigated in conjunction with advanced bicycle infrastructure, such as bike boxes and protected intersection for bicyclists. The main purpose of this research is to provide an application guideline for bicycle signals by evaluating effectiveness at urban intersections. While this study employs a simulation approach in evaluating multimodal system performance, a field test will be conducted at the City of Grand Rapids in Michigan to investigate behavior and perceptions by different groups: drivers, pedestrian and bicyclists.
