6. PHASED COMMUNICATIONS DEPLOYMENT PLAN <br />A traffic communications deployment plan was developed for the City of Eugene based on the <br />recommendations from the deployment alternatives analysis. Figure 13 illustrates the proposed <br />communications infrastructure and Table 10 includes a phased list of projects (each with a <br />description and cost) needed to deploy the infrastructure. <br />In general, the phasing order of the projects was determined based on input from City Public <br />Works and Information Services staff, project dependencies, cost, expected benefits, and <br />technical feasibility. Corridors that currently have existing communications infrastructure <br />terminating at the Pearl Street hub were given higher priority than those terminating at the <br />Roosevelt hub since the City may need to vacate the Pearl Street facility in the future. A <br />contingency project is included at the end of Table 10 to relocate the Pearl Street hub to the <br />Regional Information System (RIS) in the event this must happen before deployment of many of <br />these communications projects. The detailed list of phased projects generally deploys <br />communications in the following sequence: <br />3. Coburg Rd fiber trunk line <br />4. WillakenzieNalley River unserved area <br />5. Franklin Blvd fiber trunk line <br />6. 6` Ave fiber trunk line <br />7. 11` Ave fiber trunk line and nearby unserved areas <br />8. Willamette St/Amazon Pkwy fiber trunk line and nearby unserved areas <br />9. Remaining downtown areas <br />10. River Rd /Chambers St fiber trunk line <br />11. Hwy 99 fiber trunk line and nearby unserved areas <br />The phasing is flexible and some projects may be pursued earlier than shown in Table 10 as <br />opportunities arise. Opportunities may include partnerships with other agencies such as ODOT, <br />public improvement or private development projects along communications corridors, <br />installation of ITS devices that require communications, or new funding sources. <br />Overall, projects were developed at a manageable funding size to allow deployment as funding <br />becomes available. The initial fiber optic cable installation on a piece of a corridor typically costs <br />more than the following pieces because Ethernet over copper (EOC) devices will need to be <br />installed in each traffic signal controller cabinet that was previously connected to the twisted pair <br />copper interconnect homerun that does not fall within the limits of the fiber optic cable <br />installation. As fiber optic cable is extended along the rest of the corridor during subsequent <br />projects, the EOC devices may be removed where fiber optic cable and components are <br />installed. These EOC devices may then be used on other corridors. <br />DKS Associates Eugene Master Traffic Communications Plan March 2008 <br />Page 33 <br />
