 3.1 Diamond Lane / Elm St / Wessel Petroleum / Cooroy Motel Intersection
The Wessel Petroleum and Cooroy Motel access to Diamond Lane is located approximately 8m
from the Elm St intersection. It is also located approximately 25m from the location where the slip
lane from Diamond St joins Elm St. The location and alignment of these intersections are non-
compliant with current standards.
The proposed development would remove the Cooroy Motel access onto Elm St and Diamond
Lane. Removing the access to Elm St is in line with the requirement to limit direct access to major
roads. The removal of the access to Diamond Lane will significantly improving the safety of the
intersection. Furthermore, the proposed development will reduce the volume of traffic directed
towards the non-compliant Diamond Lane / Elm St / Wessel Petroleum access.
Some the traffic generated by the Cooroy Motel contributes to the number of vehicles traversing
this intersection. The Guide to Traffic Generating Developments by the Road and Traffic Authority
(RTA) was used to estimate the volume of traffic generated by the Cooroy Motel. Based on the
assumption of 25 units, with 85% occupancy and a caretaker’s residence, it is estimated that the
Cooroy Motel currently contributes approximately 73 vehicle trips per day. It is expected that
approximately 50% of these trips will utilise the Diamond Lane / Elm St intersection.
The proposed development will have two dwelling units accessing Diamond Lane. Based on the
Guide to Traffic Generating Developments, each of these units can be expected to generate
between 4 and 5 vehicle trips per day resulting in an expected total trip generation of 9 vehicle
trips per day. It can be expected that the majority of the vehicle trips will travel through the
Diamond Lane / Elm St intersection. The proposed development will decrease the amount of
traffic to the Diamond Lane / Elm St intersection by approximately 27 trips per day.
