                                                                                           Traffic Impact Assessment



                 4.2         Traffic Generation

                 In determining the predicted traffic generation for the site, reference has been made to the
                 RTA Guide to Traffic Generating Developments, 2002. Using the rates stipulated in this
                 document combined with engineering judgement, we have estimated the predicted traffic
                 volumes at each of the access points during the morning and evening peak periods.

                 4.2.1     Serviced Apartments
                 The RTA stipulates a rate of 0.1-0.2 peak hour vehicle trips per dwelling for housing for
                 ages and disabled persons. As such, we have adopted a rate of 0.2 peak hour vehicle trips
                 per dwelling for the Serviced Apartments proposed within the site.

                 4.2.2      Independent Living and Apartments
                 For the Independent Living and Apartment land uses, we have conservatively assumed a
                 rate of 0.4 peak hour vehicle trips per dwelling. This has been assumed to account for the
                 higher usage of private vehicles amongst occupants of these land uses when compared to
                 the Serviced Apartments.

                 4.2.3     Aged Care
                 The RTA Guide to Traffic Generating Developments, 2002 does not provide specific
                 guidance on the calculation of vehicle trips associated with Aged Care facilities such as
                 those provided by Blue Care. Whilst the abovementioned RTA rate is appropriate for
                 application to the Serviced Apartments, we believe the trip making characteristics of the
                 Aged Care facilities during peak hours will be more closely related to staff numbers due to
                 the generally long stay nature of such beds.
                 Based on discussions with Blue Care, it is understood that the proposed Aged Care facility’s
                 staffing schedule (incorporating community services and hospitality) is to be as shown in
                 Table 4.2.3 below

                 In accordance with the above table, it has been assumed that a total of 20 vehicle trips are
                 generated by staff employed by the Residential Aged Care facility during the AM peak
                 period (7:45am - 8:45am). Similarly, a total of 32 peak hour vehicle trips has been assumed
                 for the PM peak period (3:00pm - 4:00pm)
                 In addition to the above, anticipated traffic generation by visitors to the Aged Care facility
                 has been accommodated for by the application of a rate of 1 peak hour vehicle trip per 10
                 beds.
