The document discusses transportation system management and operations (TSMO) and travel time reliability. It outlines how TSMO focuses on optimizing traffic management, traveler information, incident management, and demand management using multimodal and technology-based approaches. Travel time reliability is defined in terms of variability in travel times and key measures like buffer time. Ways to improve reliability include incorporating TSMO strategies, providing better traveler information, managing incidents and special events, and implementing roadway performance strategies. The transportation landscape is changing due to trends in demographics, the environment, technology, and other factors. Agencies should respond by prioritizing performance-based projects, integrating data and technologies, and partnering with the private sector.
