Throughout the streetcar alignment, TSP would result <br />in a 0.05 decrease in ICU during the AM peak hour and 0.01 decrease during the PM peak hour. Detailed ICU <br />worksheets are provided in Appendix E. <br />3.4.3 TSP Run Time Savings <br />The following tables present the overall run time savings for all signalized intersections and at <br />Main/Broadway/Bristol, respectively. The run time savings assume a roundtrip along the streetcar alignment. <br />Table 3-9 Run Time Savings -All Signalized Intersections along Route <br />on <br />AM <br />PM <br />l Intersections Analyzed (sec / hr) <br />7TDelayReduction <br />3,030.4 <br />3,112.6 <br />vings (min./hr.) <br />50.5 <br />51.9 <br />(Minutes per Streetcar) <br />3.9 <br />3.7 <br />Table 3-10 Run Time Savings -Addition of TSP to Main/Broadway/Bristol <br />"? 16 <br />
