Abstract:Pedestrian safety has been a major concern throughout the 140-year history of the automobile, resulting in the development of numerous safety treatment options for mid-block pedestrian crossings. These include several types of beacons and signals. Some of these devices use flashing yellow beacons to alert motorists to pedestrian presence, while others include a red light to make it mandatory for motorists to stop and allow pedestrians to cross. Most of these electrical devices can be augmented with physical features such as raised crosswalks that force vehicles to slow as they approach the crossing, or mid-block pedestrian refuge islands that allow pedestrians to cross wide streets in two stages. In Nevada as throughout the United States, inconsistent device selection has resulted in undertreatment at some pedestrian crossings and overtreatment at others. This report summarizes the project team's research and recommendations on methods for selecting appropriate treatments based on local site conditions. Much of this work is encapsulated in a Microsoft Excel workbook intended to assist practitioners with identifying the most cost-effective treatment type based on expected pedestrian safety benefits. In addition, this report explores the effects of Rectangular Rapid-Flashing Beacons (RRFBs) and Pedestrian Hybrid Beacons (PHBs) on pedestrian and motorist delays under various signal timing strategies for the high-volume conditions typical of major arterials in the greater Las Vegas area. The report's appendices include a detailed literature review and other supporting documentation.
