5.3 Petrol Filling Stations in relation to Highway Design
5.3.1 Location of Petrol Filling Stations
5.3.1.1 Consideration must be given to what existing facilities are already available in the area when
applications for new petrol filling stations or service areas, consisting of more than one petrol
filling station and other auxiliary services, are made. Except as otherwise specified, petrol filling
station in this chapter refers to conventional petrol filling station, petrol cum liquefied petroleum
gas filling station and liquefied petroleum gas filling station.
53.1.2 Petrol filling stations must be located such that interference with traffic flow on the frontage road
and any adjoining roads is minimised, and no additional traffic hazards are created.
5.3.1.3 Petrol filling stations should be located such that the journey distance for vehicles seeking petrol
is minimised, but at the same time avoiding any undesirable increase in traffic flow in adjacent or
surrounding roads.
5.3.1.4 Turning movements into or out of the petrol filling station from/to the opposite traffic direction
to the traffic immediately adjacent to it should be prevented. On Local Distributor Roads or
below for example such movements can generally be tolerated.
5.3.1.5 Generally petrol filling stations should not be located adjacent to Trunk Roads and Primary
Distributor Roads. However on Expressway, petrol filling stations should preferably form part of
service areas.
5.3.1.6 It is desirable where two or more petrol filling stations are adjacent to each other that access to
and from the main road is obtained via a common service road.
5.3.1.7 Sight distances in accordance with the minimum desirable standards on section 3.3.5 of Chapter
3 should be provided on the approach to the service area or petrol fitting station, and for vehicles
leaving the service area or petrol filling station in accordance with section 4.3.8 of Chapter 4.
5.3.1.8 Service areas or petrol filling stations should preferably be sited opposite each other on dual
carriageway roads. If they are single carriageway roads then they should be staggered within
visible distance of each other, but not less than 100m apart, with the nearside filling station being
the nearest to the approaching traffic on that side.
5.3.1.9 Where it is agreed that a filling station should be provided on a Trunk Road, including
Expressways, or a Primary Distributor Road, or a Rural Road, the following must be taken
account of:
(i)
(ii)
(iii)
(iv)
Filling stations should not be located on any slip road of a grade separated junction.
On Expressways the petrol filling station, or service area, should be at least 2km from any
intersection.
Merging and diverging lanes commensurate to the design standard of that road must be
provided at access and egress points to and from the service area or petrol filling station.
The spacing between petrol filling stations or service areas should be at least:
(a)
(b)
10 km on Expressways, and
5 km on Trunk Roads and Primary Distributor Roads.
