Abstract:
Road transportation network is the biggest issue in the cities of the
developing countries. Sri Lanka is one of the fast growing country in Asia and this
country is facing many difficulties to solve the problem regarding the road traffic
conjunction and it associated problems. Vavuniya city is the one and only service point
for all the areas of the Vavuniya district. More than 80000 people of this district access
this service point for their day today activities in every day. This study is discuss about
the road transportation network problem of the Vavuniya urban council area. In that
way the main objective of this study is to mapping the road transportation network to
identify the road transportation network problem and provide the appropriate solution
for this problem. Primary data such as discussion and unstructured interviews,
secondary data such as land use map, topographical map and road information data
from urban council of Vavuniya were used to this study. Descriptive statistical method
and mathematical analysis (alpha, beta and Cyclomaric number index) and Arc GIS
10.4.1 version used to analysis the data and mapping the information. There is high
density in road network has been identified and there is a low density of road network
has been identified as per the divergence orbit of the city. There is no regularity in the
accessibility of the sub road with the A, AB and B grade road. Structural Conditions
of the road in the sub urban area is in a very poor stage. Some road of the city such as
1st Cross Street, 2nd cross street, Mosque Street and market road have high vehicle
traffic due to the access of huge number of vehicles in particular time. Some road such
as Thirunavatkulam, Kovitputhukulam, and Santhsolai roads cannot be used during
the rainy season due to the bad condition of the road. Traffic signal system has to be
established in the main junctions of the city. Extending the important services,
decentralize the administrative complex to other parts of the Vavuniya district would
be the solution for the road traffic problem of the Vavuniya city.
