4.0 TRAFFIC OPERATIONS

4.1   Traffic Generation

      The Department for Transport and Main Roads (DTMR) Road Planning and Design Manual and former
      Roads and Traffic Authority (RTA) Guide to Traffic Generating Development provide traffic generation
      rates for visitor accommodation and residential uses as follows:
               visitor accommodation (motel): 0.4 trips per unit
               medium density residential: 0.6 trips per unit

      The predicted peak hour traffic generation for the existing approved use and the proposed development
      is shown in Table 4.1.

                                                                                                   TRIPS
       LAND USE                                   SCALE       TRIP RATE             SOURCE
                                                                                                 (VEH/HR)
       Existing Approval

       Visitor Accommodation                 62      Units           -             HTC Report        30


       Proposed Development

       Visitor Accommodation                 20      Units   0.4 trips per unit       DTMR            8
       Residential Use                       38      Units   0.6 trips per unit       DTMR           23
       Total                                 58      Units                                           31
                                                                                  NET INCREASE      1 trip


      Therefore, the proposed development of the site is not expected to significantly increase peak hour
      traffic generation over the existing approval. The one additional trip predicted is negligable and well
      within the daily fluctuations in traffic.

4.2   Traffic Impact

      Based on the above, the proposed material change of use is not predicted to have any adverse impact
      on the safety or operational efficiency of the surrounding road network and no additional upgrade works
      would be required to mitigate the impact of the development.
