dc.description.abstract |
A bypass road is one of the strategies introduced to reduce traffic congestion in small and
medium sized towns in Sri Lanka. However, a limited number of studies have been carried
out to examine the impact of bypass roads in towns where the main transport route is
replaced by another outside the town. In such a context this study explores the effects of
bypass roads on build form of towns and also investigates the changes of land use and
building density, along with accessibility. The small towns analysed are Avissawella,
Mawenella, Balangoda and Piliyandala in Sri Lanka. The study has utilized network
centrality assessment to analyse the changes in accessibility. Finally, the findings of
temporal changes are compared and contrasted with theories and the key factors that
influence built form changes are identified. The results of the above four case studies
indicate three scenarios: i. The bypass road has more accessibility than the existing main
road and new land uses and high-density areas emerge along the by-pass road, making this
the main centre of the town. ii. Both bypass road and the existing main road show similar
levels of accessibility and attraction. iii. Accessibility of the existing main road remains
higher than the bypass road and very few new lands uses and build up areas are attracted
towards the bypass road - thus the existing main road remains the main centre of the town.
According to the results, if the accessibility of the new bypass road is stronger than the
existing main road, the commercial activities and buildings move towards the bypass road,
However, if the new bypass road has no influence over the accessibility to the town, the
commercial activities and buildings of the main town remain as they are. The results confirm
that spatial and economic forces are closely interrelated as indicated in the theory of the
natural movement economic process. However, the study found out that the above forces
are constrained by natural barriers. Accordingly, it is suggested that these findings are useful
for transport engineers when making new strategies to implement bypass roads and also to
urban planners when they develop local development plans after implementing bypass
roads. |
