Computer-Aided Dispatch and Automatic Vehicle Location System Best Practices

This paper describes how many transit agencies in the United States have made investments in computer-aided dispatch and automatic vehicle location (CAD/AVL) technology in order to achieve better command and control of their fleets, security, performance measurements, etc. For various reasons, these systems are not operated in a manner to reach their full potential, and therefore, often fail to meet agency expectations. Booz Allen Hamilton recently performed a study for one agency that is in the process of taking over the operations and maintenance of its system. This study included interviews of seven transit agencies that have been operating CAD/AVL systems for several years. The study found that the agencies undergo three stages throughout the realization of their expectations of the systems. The first stage, termed “Maintenance Mastery,” involves taking control of the management of the system. The second stage, “Data Validation,” involves validating that the system is working correctly and gaining an understanding of the capabilities and limitations of the data. In the last stage, the agency finally transitions use of the system across the agency. This final stage is System Adoption. This paper discusses common fault areas that can cause these projects to fail, and presents best practices from actual implementations across the United States. The study focus was on the following key best practice areas related to introducing CAD/AVL to transit operations: (1) staffing models and structures; (2) reactive and preventative maintenance measures; (3) changes to standard operating procedures; (4) data validation techniques; (5) management and development of reports; (6) training and outreach; and (7) governance and senior leadership involvement.
