Integrating Business Processes to Improve Travel Time Reliability

This volume addresses various ways that transportation agencies can reengineer their day-to-day business practices to help improve traffic operations, address nonrecurring traffic congestion, and improve the reliability of travel times delivered to roadway system users.

Project L01 inferred from a series of case studies how various business processes contributed to improving travel time reliability and the extent the business processes informed one another. The contractor conducted a series of case studies and a workshop to test the approach to be set out in guidance for operations managers and other transportation practitioners. The case studies mainly concerned domestic projects, but also addressed an element of Active Traffic Management in Europe. A key portion of the project was to identify a methodology for documenting business processes that could be adapted to evaluating various series of step-by-step actions and decisions that affect travel time reliability.
