Introduction:
Approach for
Master Plan Study:
Rural Road Planning and
implementation of rural roads into a functional and operational
unit (of infrastructure) is a disciplined exercise. Planning for
rural road like any other development planning work requires
background information and technological backstopping. This also
requires adequate and qualified manpower vis-à-vis logistic
support.
The first pre-condition for a
Rural Road Planning is social and economic data information.
This is because the road under question is an integral part of
"human centered development". Activities that of community and
households are reflected in infrastructure planning to which
road development exercise is not an exception.
Social data / information
generally cover a very large domain. Human relation, community
organization, intrinsic values, customs, festival and
accountability of communities toward physiographic, flora and
fauna etc are all integral to social relation. The
infrastructure planning such that road development cannot be
conceptualized in the absence of above; and therefore, the local
level planner has to put effort to generate "behavioral
information", of localities to which the road alignment is also
to be fixed.
Apart from, behavioral
information, the planners would also require a set of generic
information on activities. These information are important for
initial appraisal of rural road project. The objective of an
initial information is to set out economic relation. Activities,
such that agriculture production, business, trade and other
economic information of the universe are considered under
economic activities. Other than economic information, the road
related planning would also require some core economic facts. In
this regard, local planners would be interested in house hold
population size, sex ratio, settlement pattern, income and
sources of income, employment land ownership and type of assets
owned, production pattern, and household activities etc.
The type of information suggested
would generate pool of socio-economic information, which needs
to be tested along with other information. Aside social and
economic information, the local planner would also require
performance data on social services, such that, school, college,
health post, health center, hospital, private nursing home,
drinking water and sanitation service etc. Further, planner
would also be interested in service industry such that hotel,
restaurant, touristic spots. The set of data and information
suggested upon careful classification would generate useful
results. It need be noted that infrastructure planning is a
dynamic process, which cannot be justified in the absence of a
social and economic framework. Therefore, the role of local
planner at DDCs is important. Next to socio-economy is technical
feasibility. This would require:
-
Information on geomorphology
-
Geology
-
Type of rocks, its dip,
strike and strata and seepage flow etc (to decide stability
of road and structure)
-
Information on hydrology and
metrology
-
Geometric characteristics of
rural roads
-
Road design standards
-
Stope-protection and erosion
control
-
Soil conservation
-
Traffic study
-
Road width (m)
-
Carriage width (m)
-
Shoulder width (m)
-
Maximum gradient (%)
-
Pavement surface (gravel,
earth)
-
Culvert, pipe / RCC slab
-
Minimum horizontal curve
radius (m)
-
Camber slope (%)
-
Minimum vertical slope /
curve / radius (m)
-
Limitation of gradient /
length
-
Design speed km./hr.
-
Stream crossing (road way
including parapet wall), and
-
Minimum embankment height
(m), etc.
Apart from technical information
for engineering design, the alignment would also require
information environment and construction. Following information
would be useful, in this regard;
-
Impact on ecology and
environment
-
Possible disturbance to
geo-system and related instability there of
-
Deforestation problem
-
Grading and encroachment
-
Effect on "quality of life'
Corollary to engineering and
environment study effort would also require to consider the role
of people in road development, technology interpenetration and
status of markets. The current and potential market status would
reflect trade pattern. This would require price information.
Generally, retail prices are used to compute price indices.
Scope of Work and Objectives
The district transport master
plan updating is the scope of work and objective of the current
endeavor. The DC has however gone slightly beyond it and while
updating, the document proposed socio-economic data collection
technique useful for DDC in future research work.
Apart from socio-economic data
collection technique, DDC also provided due consideration to
overall ' Thinking process', to infrastructural development and
has submitted few useful insights to be considered by DDCs
during plan preparation. On technical front, the low cost road
construction technique with labour-based technology is
discussed. This is expected to serve as a guideline for future
road development works.
Methodology
The district transport master
plan was prepared by the DDC in close association of TAC. T the
outset, the data formats prepared by the TC was discussed with
full cognizance to information required and the consistency
which is required to be provided by the updated formats.
Secondly, the TAC also discussed the problem of road ownership
and it' maintenance and management problems.
The methodology is based on the
approach manual principles of the DoLIDAR (1999). Following
aspects are covered in the preparation of updated DTMP.
Review of DTMP prepared in 1997
Collection of district road
network data and plotting in the base map.
Collection of available thematic
maps.
Identification of market centers
/ services centers, industrial locations, tourist centers and
their information's. Ranking of market centers.
Preparation of Indicative
Development Potential Map
Road inventory and road condition
survey including identification of required works and tentative
costing
Preparation of Road Inventory
Map.
Preparation of rural road
inventory map.
Classification of rural road
network.
Identification of road sections
under routine maintenance, periodic maintenance, rehabilitation
an sections to be constructed.
Identification of new
transportation linkages.
Review scoring basis proposed in
DoLIDAR Approach Manual and update scoring system as necessary.
Screening and grading of new
proposed transportation linkages.
Review prioritization criteria
for periodic maintenance, rehabilitation and new construction
and update as required.
Estimation of fund requirement
for maintenance, rehabilitation and new road construction.
Prepare prioritization list
separately for roads section under periodic maintenance,
rehabilitation and new construction road sections for rural road
class A and class B roads.
Analysis of financial available
resources in last five years for rural road development.
Analysis and projection of future
fund availability for next five years (tenth five year plan
period)
Preparation of five-year road
maintenance and development plan for routine maintenance, period
maintenance, rehabilitation and new construction for rural road
class A and RR class B roads within the districts.
Prepare prospective plan map.
