Traffic Management Sub-Plan Uncontrolled when Printed: Revision D Date: May 2010 the local road users but also road users originating from outside the local area. This may include radio broadcasts, newspaper articles in regional newspapers, notification on the RTA website and variable message road signs. Traffic on Highways consists of a mix of vehicle types ranging from small vehicles through to heavy vehicles and oversize load carrying vehicles. This mix of traffic must be considered in the development of the TCP to ensure that warning signage is sufficient to meet the expected queue lengths of stopped vehicles. An additional queue length of 10% is recommended by RTA (2003) to cater for extra vehicles. An increased risk of rear end collisions arises in any location where road traffic is stopped for a period of time. Ensuring that there is sufficient warning to road users before encountering the queue is essential. 6.1.2 Collector/Sub-arterial Roads Sub-arterial roads are roads connecting to arterial roads to areas of development and carrying traffic directly from one part of a region to another (RTA 2000). Collector roads collect and distribute traffic in an area in addition to serving abutting properties (RTA 2000). Transmission line traversing sub arterial and collector roads has the potential to not only effect local road users but also road users from outside the immediate vicinity of the roadway. Consultation will be undertaken with the local council and surrounding businesses and residents (as necessary) to formulate an effective TCP. The notification process will be similar to that for a highway but with a more concentrated focus on notifying the surrounding region. As a courtesy, local police may also be notified on particularly busy roadways. A mix of traffic can be expected on sub-arterial roads but to lesser extent and with less larger vehicles than on highways, and lesser again on collector roads. This will be considered in the development of the TCP. An increased risk of rear end collisions arises in any location where road traffic is stopped for a period of time. Ensuring that there is sufficient warning to road users before encountering the queue is essential. 6.1.3 Local Roads Local roads are used primarily for access to abutting properties (RTA 2000). Local roads are predominately serviced by small vehicles and depending on the length of the roadway and number of residential dwellings attached, usually have a low volume of traffic.

Traffic Management Sub-Plan Uncontrolled when Printed: Revision D Date: May 2010 Notification of local residents is required, and as the traffic flow is to be stopped consultation with local council is to occur. An increased risk of rear end collisions arises in any location where road traffic is stopped for a period of time. Ensuring that there is sufficient warning to road users before encountering the queue is essential. 6.1.4 Access Roads Several accessways are to be traversed by the transmission line in both rural and residential localities. Access roads are characterised by very low traffic volumes, with vehicle types dominated by smaller vehicles. Notification is limited to the resident/landholder of the property and is best achieved by verbal communications to determine the most suitable method of traffic control. Verbal communications may identify alternative options for access for vehicles, thus eliminating vehicles from approaching the project area. Assessing the level and times of service (assumed to peak at business hours when residents are travelling to and from work) for accessways with landholders may identify timeframes most suitable to carry out the project works without causing delay to residents. Trenching activities along Parkway Drive access ways are predicted to only take approximately one day per accessway to complete. 6.2 TRANSMISSION LINE INSTALLATION IN A ROAD RESERVE Transmission line upgrades within the road reserve will require traffic management to direct traffic around or past works sites depending on distance of the project works from the nearest traffic carrying lane. In locations where traffic will be travelling past the worksite, traffic management will involve warning signs to inform the presence of construction workers (see Table 7.1). In locations that require diversion of traffic for construction works to be undertaken, some form of traffic control must remain in place when the site is unattended. The closure of one lane of traffic or deviation of a lane using traffic cones or bollards will be required along some routes where project works are occurring within a road reserve and of distances described in Table 7.1. This will allow for the construction in locations less than three metres (m) from the edge of the roadway and where works progress across roadways. The management methods for these partial or full road closures will be undertaken in accordance with an appropriate Traffic Control Plans (TCP) and will involve trained traffic controllers where necessary.
