' 1. EXECUTIVE SUMMARY <br />' This plan was collectively developed by City of Eugene staff from the Public Works and <br />Information Services Departments to address communications needs of the City's traffic <br />network as well as City facilities. This executive summary includes the plan objectives, plan <br />' approach, recommended communications deployment approach, expected benefits, a proposed <br />deployment plan, and recommended steps for network expansion. The remainder of the plan <br />describes each element of the project approach in detail. <br />' 1.1 Plan Objectives <br />Although the City maintains a twisted pair copper interconnect network that supports operations <br />' of 85 percent of its traffic signals plus other traffic devices (e.g. four cameras, system detectors), <br />this infrastructure is aging and has limited capacity to support future planned improvements. In <br />order to address this problem plus others, the Public Works Department would like to achieve <br />the following objectives: <br />■ Upgrade the existing communications infrastructure to support future planned <br />improvements (e.g. new traffic signals, cameras, dynamic message signs, weather <br />' stations) from the City's Capital Improvement Program and the Regional ITS Plan. <br />■ Install communications to the remaining 15 percent of the traffic signals that are <br />operating offline. <br />' ■ Relocate communications equipment from the 858 Pearl Street facility, which will likely <br />be vacated by the City in the future. <br />' Additionally, the Information Services Department (ISD) would like to deploy City -owned <br />communications infrastructure to a number of City facilities that are currently served by <br />communications leases to relieve the long -term financial burden of leased services. <br />' 1.2 Plan Approach <br />This plan is intended to meet the objectives stated above. While this plan is primarily geared to <br />' support the Public Works Department's needs, it also strives to support the needs of ISD where <br />City facilities are located near transportation infrastructure. The following approach was used: <br />1. Identify existing system deficiencies <br />' 2. Identify existing and future system requirements <br />3. Review Regional ITS Plan communications recommendations <br />4. Review communications practices in the western United States <br />5. Explore feasible technology options for use in Eugene <br />6. Analyze the communications alternatives <br />7. Select a recommended alternative <br />' 8. Develop a phased deployment plan <br />Ultimately this plan will be used to secure funding to construct the communications <br />improvements needed to support the plan objectives, <br />' 1.3 Recommended Communications Deployment Approach <br />Based on the system deficiencies, system requirements, and technology options, a hybrid traffic <br />' communications network is recommended for the City of Eugene's Public Works Department <br />that consists of a fiber optic trunk line using Gigabit Ethernet and spurs that use wireless, fiber <br />optic, or Ethernet over copper technology. Table 1 includes more detail about these <br />' recommendations. <br />' DKS Associates Eugene Master Traffic Communications Plan March 2008 <br />Page 1 <br />
