BackgroundIn India various
problems related to road network can be identified as inadequate capacity,
congested city roads, safety, lack of way side amenities, poor riding quality
etc. One of the major problems in preparing the road network improvement
strategy is the lack of large volume of data needed for it. And even if it is
available, the problem is how to manage and access the data. As the different
informations are scattered at different agencies, it is a severe problem for the
respective organisations to make any decision on the road network problem. Every
time it is mandatory for those organizations to start from scratch in planning
and executing of their work. Considering the complexities in developing,
updating and processing of transport related data there is an urgent need to
adopt new concepts on information technology in design and development on
information system for the road network. The application of GIS in particular
has relevance to road network due to the spacially distributed nature of road
related data. Thus, GIS technology provides coreframework for an integrated
information system on transportation.
Chennai, the capital of Tamil Nadu
has grown from a tiny fisherman’s hamlet during the 17th Century to the fourth
largest metropolis in India. It is housing a population of 6 million which is
expected to grow to 10 million in the near future. The Chennai metropolitan
area(CMA) covers an extent of 1172 sq.kms of which the city municipal
administration area extends to 172 sq.km. The major road network in the
metropolitan area is of ring and radial pattern with 5 radial arterials and one
Inner Ring Road(IRR). Also it is proposed to construct one Outer Ring Road (ORR)
and a by-pass road. The major roads are listed below:
- NH 5 on the North West towards Calcutta
- NH 4 on the South West towards Bangalore
- NH 45 on the Southern Direction towards Madurai
- Thiruvallur High Road parallel to NH 4
- Inner Ring Road from Kathipara to NH 5.
The rapid growth of
population and increasing number of motorised and non-motorised vehicles put the
city’s road network into a complex problem. In the existing social scenario, the
urban planner is forced to manage the existing facilities rather than to develop
new facilities. Due to the spatial distributed nature of transportation related
data, GIS technology provides the core frame work an integrated traffic
information system.
Objectives The objectives of the study
are:
- To develop a database for Chennai City using GIS
- To identify the critical links for Chepauk Zone re quiring immediate
attention.
- To propose improvements for the critical links.
