New Project Brief: Improving Travel Time Reliability
|
|
Greetings!
Travel time reliability is an emerging topic that is increasingly important to understand because of the benefits it can offer. Reliable travel times are related to improved safety, efficiencies for freight transport, and improved quality of life for road users who experience less delay and frustration. Unreliable travel times are caused by recurring congestion (bottlenecks and poor traffic signal timing) and nonrecurring congestion (traffic incidents, weather, work zones, and special events). Managing these challenges and achieving the benefits of reliability will require a common understanding among transportation policy makers and professionals regarding the concept of travel time reliability and the methods by which it can be improved. SHRP 2 Reliability research is developing products that transportation professionals can use to improve travel time reliability. A new project brief describes tools from SHRP 2 Reliability research to change business processes to support travel time reliability, to monitor travel time reliability and usefully preserve the data, to evolve the institutional arrangements of agencies, improve traffic incident scene management, and improve overall systems operations and management.
