The recreational center will <br />O g only experience minimal growth as thu number of users of the facility will be restricted by <br />ry <br />N facility capacity. <br />O. n <br />z <br />H Analysis of the impacts is limited to the 4:00 to 5:00 PM peak hour since a majority of the <br />users will travel to the facility at the end of their work shift. Most employees using the <br />t� CA H facility will travel there immediately after work. Presently, Boeing is ending the largest shifts <br />n U rA between 230 and 330 to minimize the impact on the transportation system.' Thus, the <br />impact of the trips to the recreational facility will be reduced since those trips occur prior to <br />Fa w the standard peak hour. <br />H_30W <br />The traffic impacts will be measured in terms of level -of -service. Level -of -service, as generally <br />defined, is a qualitative measure describing operational conditions within a traffic stream and <br />their perception by motorists and/or passengers. A level -of -service definition generally <br />describes these conditions in terms of such factors as speed and travel time, freedom to <br />maneuver, traffic interruptions, comfort and convenience, and safety [Highway Capacity <br />Manual (HCM), Special Report 209, Transportation Research Board, 1985]. Levelof-service <br />follow an alphabetical order from LOS "A" to LOS T". LOS "A" represents a free -Flow <br />condition where the individual users are unaffected by others in the traffic stream and LOS <br />"F is defined as forced or breakdown of flow. The LOS "F" condition exists whenever the <br />volume of traffic passing through a point exceeds the capacity of that point. <br />The 1995 edition of the HCM establishes levels of service for each facility type. These levels - <br />of -service describe the operating condition for each subject facility. For signalized <br />C%J( <br />intersections, the level -of -service is the average individual stopped delay in terms of seconds <br />pervehicle (sec./veh.). For unsignalized intersections, level -of -service is calculated for reserve <br />capacity to make a specific turning movement and is measured in passenger cars per hour <br />(pcph). Table 1 illustrates the general range of vehicular delays associated with the level - <br />of -service for signalized intersections. <br />r �► <br />TABLE 1 <br />LEVEL -OF -SERVICE CRITERIA <br />FOR SIGNALIZED AND UNSIGNALIZED INTERSECTIONS <br />Average <br />Level -or -Service Stopped Delay Reserve <br />f <br />Per Vehicle capacity <br />(sec/veh) (pcph) <br />A 0 to 5.0 >400 <br />��►� <br />B 5.1 to 15.0 300 - 399 <br />C 15.1 to 25.0 200 - 299 <br />D 25.1 to 40.0 100 - 199 <br />E 40.1 to 60.0 0 - 99 <br />F 60.0+ ' <br />' Demand exceeds capacity excessive queuing results <br />
