Unsignalized Intersection Guide
Approximately 90% of intersections in the United States are unsignalized with over 6,000 fatalities estimated to have occurred at these types of intersections in 2007. It is vital that state and local transportation agencies consider how the design and operation of unsignalized intersections can better address safety performance, operations, multimodal needs, and other impacts. A majority of unsignalized intersections are owned and operated by local agencies. Many smaller jurisdictions do not have professional engineers on staff but must frequently make decisions on treatments at unsignalized intersections. All transportation agencies need practical guidance to assist them in arriving at and justifying these decisions to policy makers and the public. The objective of this research is to develop a comprehensive guide to enhance the safe operation for all users of unsignalized intersections. The guide should be practical and multimodal and aid practitioners in selecting design, operational, maintenance, enforcement, and other types of treatments to improve safety, mobility, and accessibility.
