arRaAuaClInnate Ac i Plan <br />Transportation & Land Use Q <br />Corridors with synchronized and coordinated traffic signals <br />tend to have shorter travel times, less delay, and reduced <br />congestion. These factors combined reduce fuel usage and <br />emissions. Historical studies have indicated that signal timing <br />improvements can reduce <br />GHG emissions in a corridor <br />by as much as 10 %. The <br />Orange County Transportation <br />Authority (OCTA) has an on- <br />going program to implement <br />traffic signal coordination and <br />synchronization along major <br />corridors throughout Orange <br />County. <br />For this measure, the City will <br />identify five additional corridors beyond those implemented by <br />OCTA, where traffic signal synchronization will be implemented. <br />The City will be responsible for the planning, design, and <br />construction of these improvements to complement what OCTA <br />is already committed to providing. <br />This strategy will require capital investment by the City. Traffic <br />signal synchronization within a major corridor can cost upwards <br />of $500,000 for planning, engineering, and construction, based <br />on similar budgets for these projects throughout Orange County. <br />The City will deploy this strategy on lower volume roadways <br />beyond the regional corridors already identified by OCTA, which <br />is estimated to lower the cost to approximately $200,000 per <br />Corridor, or $1,000,000 for the measure as a whole. It is possible <br />that some of this funding could be obtained through grants and <br />other agencies, but it is likely that the implementation of this <br />strategy would require some level of investment. <br />75B -39 <br />Type of Measure <br />Voluntary <br />Emissions Reduction <br />In 2020 <br />2,504 MTCCze <br />Emissions Reduction <br />in 2035 <br />5,864 MTCCze <br />Co- Benefits <br />Reduced energy cost — residents; <br />improved air quality; improved <br />health <br />Cost to City <br />Medium to High <br />................... ............................... <br />Private Cost <br />None <br />................... ............................... <br />Potential Funding Sources <br />Grants; Measure M funding; <br />General Fund <br />Ease of Implementation <br />Medium <br />
