Traffic engineers and planners have the day-to-day responsibility to maintain the safety and operational efficiency of streets and highways in their jurisdictions. Managing traffic control devices (TCD's) is a key element in meeting this responsibility. Microcomputer technology has emerged for the management information on signs, pavement markings, traffic signals, and street lights, but these systems are limited by their single-device orientation and lack of routines to enhance the traffic control device management process. The potential for such an integrated system, however, was recently demonstrated in Norfolk, Virginia. The Norfolk Traffic Control Device Information System (NTCDI) is described.
