The report is based on a series of case studies, from the United States and one from Great Britain, that describe successful business processes. The case studies show how business processes were successfully improved in operational areas such as traffic incident management (TIM), work zone management, planned special-event management, road weather management, and traffic control system management. This report and an accompanying guide also provide a detailed introduction to business process mapping. The approach to business process mapping used in this report and the guide was developed by the IBM Corporation for use in automating business processes, called Business Process Modeling Notation (BPMN). This approach proved highly adaptable to business processes related to traffic operations. BPMN Business processes diagrammed using BPMN are simple to comprehend and communicate. This report, along with the accompanying guide (which focuses on showing how to use BPMN for mapping traffic operations business processes) and other SHRP2 Reliability track products related to institutional structures and business process reengineering, are intended to help transportation agencies move forward in addressing nonrecurring traffic congestion and delivering more reliable travel times on their highway networks.
