3.6.2 Location of Run-ins
3.6.2.1 General
(i)
(ii)
(iii)
(iv)
Run-ins should be sited as far as possible away from junctions, horizontal curves,
summit curves, bus stops, zebra or other pedestrian crossings, railway level crossings
and other similar locations.
Where the lot abuts onto more than one road the run-in should be sited on the least
important of these roads.
For corner lots, it is generally preferable to site run-ins on the downstream side of
junctions rather than on the approach side (roundabouts excepted).
Normally there should be not more than one run-in and one run-out, combined or
separate, on any single frontage.
3.6.2.2 Grade Separated Junctions
Run-ins should be avoided at, or in the vicinity of, grade separated junctions, as they
substantially increase the accident potential. Any exceptions must receive special attention
to ensure that there is no interference with weaving or merging/diverging movements.
3-6.2.3 Signal Controlled Junctions
Run-ins should not normally be sited within 60 m of the stop line on the major road or
within 45 m on the minor road, on either the approach or exit roads.
3.6.2.4 Roundabouts
Run-ins should not normally be located on the roundabout itself or within 60 m on the exit
carriageway or 45 m on the approach carriageway. In special circumstances these distances
may be reduced to 30 m and 25 m respectively.
3.6.2.5 Uncontrolled Intersections
Run-ins should be located as far as possible away from an uncontrolled junction and
preferably not closer than 30 m. If there is a likelihood that a junction could be signalised in
the future, the distance should be that appropriate to those for signal-controlled junctions.
3.6.2.6 Horizontal Curves and Summit Curves
Run-ins should not normally be located on horizontal or summit curves. If, however, this
cannot be avoided, then the visibility distance for vehicles approaching the run-in should
preferably be appropriate to the Desirable Minimum Sight Distance given in Table 3.3.5.1,
and never less than the Absolute Minimum value.
3.6.2.7 Rear Loading/Unloading Lanes
Access should be via a rear loading or unloading lane if one is provided. However, where
the size of the development is such as to cause overloading of the rear lane, consideration
may be given to access off the public road on to which the lot abuts. On some occasions
access from both the rear lane and the public road may be necessary.
