5.          TRAFFIC IMPACT


The assessment of the impact of the proposed          development on the external road
network has been undertaken.          The impact has been analysed according to the
procedures set out in Austroads      Guide to Traffic Management and Road Design.
                                     -




5.1         Intersection Analysis (without development)


A review of the operational performance of the intersection of the Old Ceylon Road
and Cooroy Belli Creek Road bas been undertaken. According to Austroads Guide to
Traffic  Management Part 3         Traffic Studies and Analysis, Table 6.1, "At
                                     -




unsignalised intersections with minor roads where there are relatively low volumes of
cross and turning traffic, capacity considerations are usually not significant and

capacity analysis is unnecessary". Table 6 below shows the volumes where
intersections operate adequately and capacity analysis is not required.


                               Table 6   -
                                             Roadway Capacity
                                              Light cross & turning volumes
                      Type of Road           Maximum design hour volumes
                                               Vehicles per hour (two way)
                  Two Lane major road          400    I   500          650
                       Cross road              250    I   200           100


The traffic volumes on Cooroy-Belli Creek Road as stated in Table 1 of this report are
below 200 vehicles per hour and the estimated volumes on Old Ceylon Road are also
below 200 vehicles per hour. Therefore the intersection will continue to operate
under uninterrupted flow conditions and detailed analysis is considered unnecessary.




5.2         Road Section Analysis (with development)


The impacts of the proposed development on Cooroy-Belli Creek Road have been
assessed.      In accordance with the requirements of Austroads and the Main Roads
                                                                                                 "

document, "Guidelinesfor Assessment ofRoad Impacts ofDevelopment Proposals.
it states in Section 1.2 Scope of the Guidelines;


      "In general terms, a development’s road impacts are considered to be
     insignificant if the development generates an increase in traffic on the road
                                                  "
     network ofless than 5% ofexisting levels.


According to the traffic surveys the existing levels or average annual daily traffic
volume (AADT)on Cooroy Belli Creek Road is 511 vehicles per day (vpd). The
increase in development traffic is 4 vpd. Compared to existing levels the trips
generated from the site are below 5%. Therefore the increase in development
generated traffic would be less than 5% of existing levels and the impact is considered
insignificant.
