The results show thatarrivals occur over at least 40 minutes with a peak at about 25 minutes before events. The departures are moreintensified with a peak between 15 <strong>and</strong> 20 minutes after events. The frequency distribution shown in Figure 16was used for all events. This assumption was tested <strong>and</strong> found to produce reasonable results.Figure 16Observed Arrival <strong>and</strong> Departure Patterns20%18%16%14%12%10%8%6%4%2%0%-40min -35min -30min -25min -20min -15min -10min -5min 0min 5min 10min 15min 20min 25min 30minArrivalDeparture5.2 Development <strong>Park</strong>ing Dem<strong>and</strong> Trip GenerationThe trip generation analysis numbers are included in Appendix A. Table 6 shows a summary of the final results<strong>and</strong> the figure used for capacity analysis. Table 5 shows that the critical scenario is Winter Saturdays, during thenetball <strong>and</strong> Australian Rules football season. The forecast trip generation (between 7:00am <strong>and</strong> 7:00pm) isapproximately 3,600 round trips (7,200 one way trips) in Stage 1, increasing to approximately 3,700 round trips(7,400 one-way trips) in Stage 2. The forecast peak 15-minute flows are 305 in <strong>and</strong> 337 out in Stage 1, <strong>and</strong> 335 in<strong>and</strong> 337 out in Stage 2. The maximum car occupancy (parking dem<strong>and</strong>) during the day is 1,021 spaces with an85 th percentile dem<strong>and</strong> of 869 spaces in Stage 1. The respective numbers in Stage 2 are 1,070 <strong>and</strong> 890. Theseare substantially greater than the dem<strong>and</strong> for activities on any other day of the week or season.Table 5Forecast Trip Generation (Summary)DayDailyTripsto /fromWSPArrival Departure OccupancyMax 15min Max 15min Max85thPercentileFlow Time Flow Time Bays Time BaysMonday 392 54 05:30 05:45 65 09:10 09:25 229 17:55 125Tuesday 424 54 15:30 15:45 65 18:10 18:25 315 17:55 202Wednesday 1,136 132 17:20 17:35 159 21:55 22:10 560 18:50 372Thursday 368 54 17:30 17:45 65 22:10 22:25 258 17:55 203Friday 224 54 15:30 15:45 65 18:10 18:25 226 17:55 117Saturday (Summer) 308 54 08:30 08:45 65 16:10 16:25 271 15:55 248Saturday(Winter)Stage 1 3,604 305 14:00 14:15 337 15:50 16:05 1,021 10:05 869Stage 2 3,665 335 14:00 14:15 337 15:50 16:05 1,070 15:45 890Sunday (Summer) 491 70 08:25 08:40 65 16:10 16:25 252 15:55 203Sunday (Winter) 1,042 148 08:20 08:35 142 11:05 11:20 621 09:45 391The results in Table 5 conservatively assume 100% car usage <strong>and</strong> 0% linked trips for all events except for PNAevents during Winter Saturdays. For these netball events, 65 to 70 % car usage <strong>and</strong> 30 to 40 % linked trips wereassumed. These assumptions were tested against existing event schedules <strong>and</strong> observed traffic data <strong>and</strong> werefound to produce reasonable results. <strong>Car</strong> usage <strong>and</strong> linked trips are discussed further in Section 5.3.It is important to note that the above forecast traffic volumes <strong>and</strong> subsequent intersection analysis shown inproceeding sections are based on a forecast only <strong>and</strong> that the day to day variation of traffic can alter somewhatT:\60218676 - <strong>Wembley</strong> PK TA\8 Issued Docs\8.1 Reports\Comprehensive <strong>Integrated</strong> <strong>Access</strong> RevF.docxRevision F - 8 February 2012
