times for all routes in each group were summed together to provide an easy comparison of alternatives. The resulting travel times are shown in Figure 3 in the Appendix. A summary of comparisons is shown in Table 5. Table 5 — Travel Time Changes with Line Ave Alternatives' 'The percentages shown are for all routes in each category relative to the existing travel times. As shown in Table 5, and intuitively for this type of change, the travel times across the system will increase with the loss of a direct connection between Main Street and Twin Lakes Road. However, the magnitude of the impact and who receives the most impact changes based upon the alternative. In general, Alternative A represents the most impact to cut -through traffic on Line Avenue and least impact to other routes with origins and destinations within the study area. Alternative C represents the least impact to cut -through traffic on Line Avenue and most impact other routes. e. Warrant Analysis - Twin Lakes Road & 181St Avenue As presented earlier, the existing traffic at the Twin Lakes Road/181St Avenue intersection does not satisfy the volume Traffic Signal Warrants. With any of the alternatives for Line Avenue, the projected shift in traffic volumes generally results in an increase at the Twin Lakes Road/181St Avenue intersection. Because of these estimated increases in traffic, the possibility arises of a traffic signal being needed. To fully evaluate the volume signal warrants (Warrants 1-3), the changes applied to the Twin Lakes Road/181St Avenue intersection for each of the alternatives was applied to the full 24-hour period. Using these volumes, two warrants, Warrant 2 Four -Hour Volumes and Warrant 3 Peak Hour Volumes, were satisfied for all three alternatives. Up to six of the required eight hours met the criteria for Warrant 1, Eight -Hour Volumes. Although two warrants are met, traffic operations at the intersection are still satisfactory with acceptable LOS for the overall intersection and individual movements. These results suggest a traffic signal, while warranted, may not yet be justified. However, it is likely that added growth from additional development in the general area would push traffic volumes to satisfy the Warrant 1 as well as increase delays to indicate need. It is likely that a traffic signal will be needed at the Line Avenue/Twin Lakes Road intersection within a few years. Traffic volumes and operations should continue to be monitored into the future, regardless of an alternative for Line Avenue. The results of the warrant analyses are shown in the Appendix.
