Publisher's Synopsis
"This report sets out requirements for travel time reliability within a performance-based planning process. The authors present two succinct tables that describe requirements for person and freight trips for reliable transport. A discussion of goals, performance measures, and performance targets follows. Performance measures are presented that pertain to roadway users and agencies. The report examines the cost-effectiveness of different ways to improve travel time reliability. The analysis draws from a wide range of literature, but because few data on outcomes of different strategies to improve travel time reliability are available, assessment of cost-effectiveness is qualitative. Nonetheless, in perusing the tables of information, one can form reasonable conclusions about what large, medium, and small expenditures for different types of operations and capacity improvement projects can produce in terms of a small, modest, or large effec
