Project Description
Traffic Engineering Blossoms with Intellectual Modernization: The City of Lancaster has just completed two of its greatest traffic engineering projects to date, the Traffic Signal System Modernization project and the North County Intelligent Transportation System (ITS) Expansion project. These projects are being submitted as one application because they come out of the City’s Transportation Communications Master Plan, and ultimately the intended and achieved results of these projects are completely reliant upon the success of each other. These projects required multi-jurisdictional coordination with the City of Palmdale and Los Angeles County, including funding source collaboration. The Traffic Signal System Modernization project replaced the City’s aging traffic signal communications system infrastructure with a more reliable, redundant, and faster system based on current ITS architecture. The project upgraded the existing copper interconnect with fiber optic cable and CCTV camera equipment, as well as installed wireless communications to remote signalized intersections. The CCTV camera system allows the City to quickly diagnose problems and resolve them speedily so that residents experience less interruption to traffic flow. Residents are already benefiting from reduced travel times and an increased level of service. This is accomplished through the ITS receiving real-time data and making signal cycle length adjustments as traffic ebbs and flows. The North County ITS Expansion project has upgraded the City’s Central Traffic Control Management System, including the installation of new traffic signal controllers as well as new, upgraded communications equipment. Updating older hardware and software allows for more efficient systems that rely on improved ITS technologies and communications. A major result of installing all of this new equipment is the City is now connected to the Los Angeles County Information Exchange Network (IEN). The LA County IEN is a coordinated network for sharing information and control of the various traffic control systems throughout LA County, using a common network backbone based on the Common Object Request Broker Architecture (CORBA). Sharing information and control throughout LA County is intended to improve coordination between member agency traffic control systems, like Lancaster’s, as well as improve incident response and management activities. The incident and planned event tracking system in the IEN allows member agencies to share incident, planned event, and construction activities. The unique IEN scenario manager, will allow the City to establish multi-agency incident response/mitigation plans in case of a natural disaster or emergency.
