Abstract:
Road transport is vital to
economic development,
since conveyance of both
people and goods are vital for a
country's growth. Within this
context Sri Lanka too has been
investing heavily on road networks
during last few years. To sustain a
a good road network, having a
systematic road management
system is essential. In such
systems, roads are classified and
recorded along with its attributes
and all maintenance and planning
is done using this system. Therefore
road classification is the key and
having a well defined procedure to
classify roads is a must. However,
at present, in Sri Lanka, majority of
the roads are unclassified.
In Sri Lanka, vast amounts of road
infrastructure facilities have been
built in the past and is still
continuing, but ironically a proper
classification system is yet to be
implemented. Based on the current
classification system, roads are
categorized as "A" , "B" , "AB""C" ,
"D" and E class . Class A , B and AB
roads are managed by Road
Development Authority and are
considered as national roads. The
national road network consists of
nearly 12,000km of roads. Class C
and D roads are managed by
Provincial Road Development
Authorities and total length of class
C & D roads is about 16,000 km.
Over and above these roads there
are many more miles of roads that
have been built, yet not categorized
under any of these classes and
.. remained for years without a
classification. Most of these roads
are low volume roads and total
approximated length is around
70,000 km. Majority of those roads
are managed by Municipal councils,
and Pradesiya Sabhas. The
National Road Master Plan (2007-
20 17) has categorized them as E
class roads. T'he : proper
classification of all roads are
important because it ensures that
National, provincial and local
government funds are spent on the
appropriate road based on user
needs and accountability is
assured.
Accessibility depends on many
factors including the availability of
roads, their condition, design and
the means by which people can
reach them and travel on them.
Roads have two key functions
which may not be compatible with
each other, firstly, to enhance the
mobility of vehicle users and
secondly, to increase accessibility
to locations where people want to
travel to and from. Thus, high
speed roads have fewer entry or
exit points so that vehicles can
better maintain their higher speeds
whilst local roads have many points
of access to residences,
businesses and intersections
which mean that traffic must move
more slowly.
