Development Staging

It is standard practice when analysing future year traffic operations to adopt a ten year design horizon

from the year of full occupation. Therefore, the following development staging has been adopted:

== Traffic Counts: 2014
== Development Application: 2014
== Construction and Operation: 2016
— Operation plus 10 years: 2026

4.1.1 Background Traffic Growth

A background traffic growth rate of 2.2% per annum has been applied to observed traffic volumes. This
rate is consistent with the Department of Local Government, Planning and Sport and Recreation’s 2011
forecast growth rate for resident population in the Sunshine Coast region. The application of this rate

equates to a 30% increase in local traffic volumes over the next 12 years (2014 to 2026).

Traffic Generation

4.2.1 Service Station and Restaurant Drive-Through

The service centre trip generation rates contained in the DTMR Road Planning and Design Manual and
in the RTA Guide to Traffic Generating Developments are not considered suitable for this study as they
relate to service stations in urban areas. Service stations located on rural highways are likely to experience

significantly different traffic generation rates and patterns to those in urban areas.

We have previously undertaken surveys of traffic generation for three BP highway service centres located
on the Pacific Highway at Coomera and Staplyton, and on the Bruce Highway at Caboolture. Each of
these service centres comprises a petrol filling station with associated food / restaurant outlets (including

drive-through facilities).

The surveys identified the number of vehicles entering each site on a typical weekday, between the hours
of 7am - 5pm. The traffic volumes along the adjacent section of highway were also recorded to calculate

the site traffic generation as a proportion of the passing highway traffic.

Figure 4.1 shows the percentage of turn-in traffic as a proportion of (one-way) passing highway traffic for

each of the three service centre sites during the network peak hours. The data indicates that that during
