Determination of centre line markings adjacent to property access#

The purpose of this section is to provide information that assists in determining the appropriate centre line marking (a single continuous, unidirectional continuous dividing line or a double barrier line) to allow motorists from turning right either into or out of a property access, or to restrict such movement. Determination of the line marking at the centreline adjacent to a property access is highly susceptible to having adequate sight distance. Adequate sight distance is referred as the capacity for the stationary vehicle to select a gap in oncoming traffic to make the right turn, and also to have sight distance for the vehicles in behind to either stop when they have identified the presence of the stationary vehicle or decelerate and pass to the left of the stationary vehicle. Adequate sight distance is determined sufficient when standard requirements for Sight distance at property entrances and Stopping sight distance provided in the Austroads Guide to Road Design (AGRD) are satisfied. Requirements to sight distance at property entrances are provided in Part 4A of the Guide to Road Design. Requirements of stopping sight distance are provided in Part 3 of the Guide to Road Design. A single continuous or unidirectional continuous dividing line may be installed when sufficient sight distance is present and is determined as adequate sight distance to allow right-turning manoeuvres either into or out of the property access. Where adequate sight distance is not met, a double barrier line may be used to restrict such movement. Modification to the existing line marking is required when potential safety problems are identified using the methodology outlined in this document. The minimum length of double barrier line that should be marked is 40 m (that is, 20 m each side of the property access). Consideration should also be given to effects on other property accesses, which meet the assessment criteria and the presence of double barrier line marking in the near vicinity (it may be necessary to join new barrier lines with existing lines). The property owner should be consulted, given that modification of property access line marking from unidirectional to double barrier lines will always result in the restriction of one existing legal movement (for example, marking a double barrier line to restrict right turns into a property access from a road retains the status quo of the right-turn movement into the property, but makes the existing legal right turn movement from the property illegal).
