3.6 Traffic Generation
                                                           2
The Roads and Traffic Authority (RTA) of NSW recommends peak hourly and daily traffic
generation rates for housing for aged and disabled persons (i.e. retirement villages or aged care
facilities) of 0.1-0.2 trips per dwelling during the peak hour periods. These values are consistent
with the recommendations provided within the Department of Main Roads’ document “Road
                                 3
Planning and Design Manual” .

Given the proposed redevelopment would include similar aged care activities to those being
performed currently, the trip generation rate of the existing ‘aged care facility” was measured to
provide a guide as to the appropriate trip generation rate to apply for the proposed
development.

The traffic generated by the existing aged care facility, as determined from the traffic surveys
carried out at the access location, are illustrated in Table 3-2.


Table 3- 2: Trip Generation by the existing aged
                                            aged care facility

          Type            Number        Total Trips (vehicles per hour)        Peak Hour Trips per Bed
                          of Beds
                                           AM Peak             PM Peak           AM Peak     PM Peak
Aged Care Facility           110               22                  31               0.22       0.28

For the purpose of this report, it has therefore conservatively been assumed that the additional
beds would generate traffic at the same rate as the existing beds. Adopting this rate, the traffic
likely to be generated by the additional 32 beds would be in the order of 7vph during the AM
Peak and 9vph during the PM Peak.

It is also noted that the traffic generation rate for the existing facility (which was adopted for the
expended facility) is similar, albeit more conservation, than the traffic generation rates for housing
for aged and disabled persons recommended within the RTA and DTMR guidelines.
