The modern advanced traffic management system (ATMS) is made up of three parts: the computer hardware, including intelligent controllers; software including ATMS system software, operating system software, and network software; and the communications system, which includes network and remote communications. The Las Vegas Area Computer Traffic System (LVACTS) uses the 2070 Advanced Transportation Controller for the intersection intelligence and storage of the local intersection database. The software used on these controllers is the Next Phase (Trademark) Intersection Management Software. The central database is stored on a server at the LVACTS control center and replicated to a backup server also located at the control center. User interface graphics and upload/download control, including system maps and intersection status graphics, are stored locally on the user workstations in the control center and on workstations at the jurisdictional management centers (JMCs) located in North Las Vegas, Henderson, Las Vegas, and Clark County. LVACTS uses Integrated Control Of Traffic Networks (icons--Trademark) for this purpose. The focus of this paper is the design of the network communications system, including the servers and workstations; the bridges, routers, and switches; and the microwave and fiber optics communications that tie all of these control centers together to make up the LVACTS system.
