c <br /> TRIP GBNSRATION <br /> Based on the 4th edition of the Institute of Transportation <br /> Engineera Trip Generation oanusl, the proposed day care will <br /> generate 123 tripa during the P.M. peak traffic hours, with <br /> 48 percent entering and 62 percent exiting. The day care <br /> will generate 670 daily iaeekday trips, and 114 tripe during <br /> the morning peak hour. <br /> The day care tril� diatribution is based on the existing <br /> traffic volume pa�terna at the Tower Street / Nortk Broadway <br /> interaection and the known destination of parents dropping <br /> off their children. Approximately 10 percent of the trips <br /> are aesumed to �be made by DSHS employees; the rest of the <br /> trips ere bound for the college. Although many of the <br /> college bound tripe will use the nearby parking lots, they <br /> were sll routed along Toxer Street into the main campua <br /> parking nreas to create a "worst case" scenario. <br /> Ae diacussed below in the level of aervice sectian of this <br /> report, the afternoon peak hour is the most aignificant and <br /> was used to analyze the traffic impecta. In the afternoon, <br /> entering traffic ia assumed to enter ToWer Street from <br /> , either the campua or the State of Washington offices nearby, <br /> and will not �ae the arterial street syatem to any extent. <br /> Traffic exiting the eite will split 37 percent to the north <br /> and 58 percent to the south st the North Broadway <br /> interaection. The remaining 5 percent will crose Broadway <br /> and enter the ahopping area. Figure 2 ahows the p.m. penk <br /> hour trip generation, distribution and routing for the <br /> project. Figurea 3 and 4 illustrste the a.m. peak hour <br /> traffic and the average weekday traffic respectively. <br /> LEVEL OF SERVICfi <br /> An intersection level of service ( LOS ) calculation for the <br /> year 1980 p.m. peak hour was performed for the existing <br /> interaection geometry and lane ussge. Since the morning <br /> peak hour has aignificantly lower volumes, about b7 percent <br /> of the afternoon peak, separate calculations were not <br /> performed for the a.m. peak. Traffic on North Broadway was <br /> projected to 1990 from the 1988 counts obtained from the <br /> City of Everett by adding four percent per year to those <br /> counte. �+8%) . <br /> The intersection currently operates at LOS B ( 11 .87 seconds <br /> delay) during the p.m. peak traffic hour, and will continue <br /> to operate at LOS B ( 12.48 seconds delay) after construction <br /> � of the day care. <br /> 2 <br />
