Practical measures could be employed to reduce the actual impacts.Hockey, archery and other ad hoc uses will not result in material changes to peak demands, due to limitations inplaying fields.The State Netball Centre will be used by Netball WA and VenuesWest as well as the PNA to host events. TheNetball WA events will be regular and thus have been included in the model.VenuesWest events will be irregular and thus have not been included in the model. However, a discussion of theimpact a VenuesWest event may have on parking has been included in Section 5.2.Should there be a significant increase in activities on-site (such as more than 41 games of netball at any one timeor any other change that will increase overall vehicle trips to site) then a new study may be required to assess thetraffic impact and parking demand and identify management and mitigation measures.Car Usage and Linked TripsTo convert the forecast number of people to trips, assumptions were made in regard to car usage (cars perperson) and the proportions of linked trips. Linked trips are trips where different people travel in the same car orwhere the same people attend different events. The analysis was first run assuming 100% car usage and 0%linked trips. This assumption was tested and adjusted as required to reflect the observed number of cars. This isfurther discussed in Section 5.2.Arrival and Departure PatternsIn order to assess the impact of the forecast car trips a frequency distribution had to be assumed to forecast thearrival and departure patterns. From the video survey (Saturday, 6 August 2011) it seems as if the arrivals andT:\60218676 - Wembley PK TA\8 Issued Docs\8.1 Reports\Comprehensive Integrated Access RevF.docxRevision F - 8 February 2012
