It can also be useful to financial personnel, traffic engineers, planners, and security and enforcement personnel. In addition, it provides information to those concerned with environmental issues such as drainage, runoff, lighting, noise, and air quality. The report focuses on the design factors affecting toll plazas, including traffic, toll collection methods, location and configuration of toll plazas, as well as congestion management, operation and maintenance of the facility, and environmental issues. The synthesis includes discussions of existing standards and practices related to toll facility design, including plaza and roadway geometrics, lane configuration, electronic toll collection, capacity, access, communication, safety and security, signing, pavement markings, and new technology.
