4.0 Traffic Impact Assessment
The proposed development is a Residential Aged Care Facility providing a total of 90 beds.
The RTA Guide to Traffic Generating Developments provides traffic generation rates for various land uses. It suggests a
rate of 0.1 - 0.2 trips per dwelling in the evening peak hour, for housing for aged and disabled persons. Appendix 3A in
TMR’s Road Planning and Design Manual suggests that this rate is appropriate for retirement / ages homes.
It is acknowledged that this trip generation rate relates to ‘dwellings’ (e.g. independent living units) rather than beds.
However in the absence of published trip generation rates on a ‘per bed’ basis, the rate at the higher end of the range has
been applied to the proposed development (i.e. 90 beds x 0.2 trips per bed). This is considered to be a reasonable
assumption given that the staffing requirements for an aged care facility (as opposed to independent living units) are
higher, but the traffic volumes generated by visitors are likely to be lower, and the traffic volumes generated by residents
will be negligible.
The application of this trip generation rate (i.e. 0.2 trips per bed) suggests a peak hour traffic generation of 18 vehicle
trips in the peak hour, or one (1) vehicle trip per 3 – 4 minutes on average, during the critical peak hour.
This level of traffic generation is clearly very low, and likely to be well within the typical fluctuations in background
traffic volumes on the local road network, therefore negligible from a traffic engineering and transport planning
perspective.
Furthermore, this does not take into consideration the existing uses (i.e. nine (9) residential dwellings) on the subject
site. These dwellings would currently generate in the order of 7 – 8 vehicle trips in the critical peak hours (assuming
0.85 trips per dwelling as recommended in the RTA Guide to Traffic Generating Developments), therefore the net impact
of the proposal would be only 10 – 11 additional vehicle trips in the peak hours, or one (1) additional vehicle trip per 5 –
6 minutes on average, during the critical peak hour.
As a consequence of the above, no external roadworks are required to support the proposal, and any impacts (however
minor) would be mitigated by way of infrastructure contributions payable as part of the redevelopment of the site.
