Dennis \\'elsch \hrch 24, 1997 Page 19 The minimum acceptable le"el of congestion for design rurposes \"aries by municipality size and dri\'€r expectations. For larger metropolitan areas, the minimum acceptable level of congestion is usua11y LOS "D." In smal1er, more rural communities ,,"here drivers tend to be less aggressi\'e, the minimum acceptable le\'el of ser,ice is typica11y LOS "C" For the purposes ot this analysis, the minimum acceptable le\'el of seI\'ice was assumed as LOS "D." Capacity analyses i\'ere conducted for each of the nine key dri"€"say and intersection ]OCCit10ns. The analyse:::- \\'ere conducted by using the pocedures c)uthned in tne 1994 Hi~ni\'a\' Caracitv Manual Crdate and tne e\.istir:s intersection t;eome;ics and ';;'aHic control. The results of tne anal:~-2s ?re doct;:-;-,ented in 1":':-1,,, :" The data indicate that the existing P\1 peak nour conditions at eacn of the nine key intersections is currently acceptable (LOS D or better) and that the conditions at each of tne intersections would be expected to remain acceFt2.ble if the de\'€lopment did not occur (i,e" under the Year 2001 Background conditions,). The data also indicate that se\'en of the nine intersections should operate acceptably ti:,dc?r the l'ear 2001 Post-Development P~1 peak hour conditions. The t-,,"O e>,.::eption5 ',,'ould be the C]e\'eland Asenue intersections with ),'orth Centre Pomte Dri\'e and Lydia A\'enue where the side street left tuming mo\'ements onto Cleveland Avenue are expected to operate under congested conditions during the Year 2001 Post-Development PM peak hour, Signal Warrant Analyses Traffic signal \\'arrant ana1y::.es were conducted for each of the four unsigna1ized key inten;€'ctions for the existing, Year 2001 Backgrou.I'ld and Year 2001 Post-Development time periods. The Manual on Uniform Traffic Control Devices specifies 11 traffic signal warrants with various threshold or requirement values. Most of the warrants are based on satisfying various minimum combinations of major and minor street volume. The minimum threshold values are reduced to 70 percent of their requirement values when the 85th percentile speed on the major street is above 40 mph and/or the intersection is located within a community of 10,000 persons or less. If and when an intersection's traffic demands meet or exceed the-threshold requirements, it is an indication that a traffic signal may be installed. A traffic signal is not required just because an intersection meets one or more of the specified signal warrants.
