DENVER RTD'S COMPUTER AIDED DISPATCH/AUTOMATIC VEHICLE LOCATION SYSTEM: THE HUMAN FACTORS CONSEQUENCES

This report documents what happened to employees' work procedures when their employer installed Computer Aided Dispatch/Automatic Vehicle Locator (CAD/AVL) technology to provide real-time surveillance of vehicles and to upgrade radio communication. Denver's Regional Transportation District (RTD) acquired a CAD/AVL system and installed it systemwide. The Operator Performance and Safety Analysis Division, DTS-79, at the U.S. Department of Transportation's Volpe National Transportation System Center performed the research with the support of the Federal Transit Administration's Advanced Public Transportation Systems Program. The analyses examined the usability of the CAD/AVL features and how CAD/AVL affected the employees' work tasks. Employees' responsibilities remained the same, but they received additional information. Dispatchers transmit and receive more calls. Street supervisors' duties have expanded, but their staffing level is unchanged. Bus operators use new communication procedures, but initially, expressed discomfort with the surveillance capability. RTD can better manage their transit operations because the CAD/AVL system reduces the time they need to respond to incidents in the field.
