Description: "Reliability of transport, especially the ability to reach a destination within a certain amount  of time, is a regular concern of travelers and shippers. The definition of reliability used in  this research is how travel time varies over time. The variability can apply to the travel times  observed over a road segment during a specific time slice (e.g., 3 to 6 p.m.) over a fairly long  period of time, say a year. The variability can also pertain to the travel times of repeated trips  made by a person or a truck between a given origin and destination. Agencies are increasingly  aware of the issue of reliability, although the transportation industry as a whole as yet  lacks a firm understanding of the causes and solutions to failures of reliability. As the agenda  for the SHRP 2 research on travel time reliability took shape, it became clear a fundamental  study was required to be able to talk about travel time reliability in a meaningful way"--Foreword.
