Summary Comparison of Alternative Circulation Networks <br /> <br />Alternative A has 21% less morning congestion but 29% more evening congestion <br />than the existing baseline conditions. LOS E and F intersections are reduced by <br />four in the mornings, but are increased by one in the afternoons. Compared to <br />Alternatives B and C, Alternative A has more LOS E and F intersections and more <br />average city-wide delay. Regarding average arterial delays, Alternative A routes <br />are projected to have increased delay relative to the existing conditions (with <br />notable exceptions for morning westbound/southbound travel). Average overall <br />delay, both directions, for selected routes is about 10 percent greater than at present, <br />about the same as for Alternative B but about 3 percent worse than Alternative C. <br /> <br />Alternative B produces about a 6% less overall city-wide delay at intersections in <br />the morning and 11% less in the afternoon compared to the Alternative A network. <br />Alternative B has more delay and more LOS E or F intersections than Alternative <br />C. There are two fewer LOS E or F intersections than Alternative A, but one <br />remains in the morning and six in the afternoon. Alternative B overall has about 11 <br />percent more delay on these arterial routes (both directions) than existing <br />conditions. Its routes in the aggregate have slightly more delay than the equivalent <br />land use scenario on the Alternative A network. The eastbound afternoon direction <br />is the most congested, with morning and westbound afternoon arterial levels of <br />service typically at LOS C and D. <br /> <br />The Alternative C street network produces the fewest LOS E or F intersections and <br />the least total peak hour delay for the three alternatives. Average delay increases by <br />11 percent compared to existing conditions and has 15 percent and 5 percent less <br />delay than Alternatives A and B, respectively. Alternative C has the least delay of <br />the three alternatives, with route delay increasing by about 6 percent in the <br />aggregate (all routes, both morning and afternoon). <br /> <br />General Conclusions <br /> <br />· The intersection improvement mitigations assumed for Alternative A and listed <br /> in Appendix A are very important for improved future traffic conditions. <br /> <br />The key extension included in Alternative B is the E1 Charro Rd. extension to <br />Stanley Blvd.; the other road widenings/extensions would not be critical to <br />levels of service or capacity, but would reduce traffic volumes on certain streets. <br /> <br />Alternative C represents a marginal improvement in levels of service and <br />delays citywide compared to the other two alternatives but is not necessarily <br />better when considering selected routes through the city. <br /> <br />· When considering levels of service on individual intersections, there is little <br /> difference among the three altematives. <br /> <br />4 <br /> <br /> <br />
