Scope and Objectives

The main objective of the study is to evolve a comprehensive methodology for planning and evaluation of rural road network. The specific scope and other objectives are:
• To review the network planning, project appraisal methods and evaluation techniques adopted worldwide for selection and prioritizing of rural roads.

• To study the planning practices adopted at macro and micro level for development of rural roads in India and its implications on socio-economic development.

• To evolve a methodology for selection of best link options for unconnected villages at Block level.

• To develop investment options and ranking of the rural roads based on the criteria of accessibility and economic benefits.

 
Methodology
The present study reviewed the historical aspects of network planning and project appraisal methods and proposed a methodology to evaluate the rural connectivity at block level. This approach is based on functional accessibility of villages with the hypothesis that the population of the unconnected villages will have to travel to the nearest major centres using the existing tracks or fair-weather roads to access the functions that are missing in their villages. The optimum routes for connectivity of unconnected villages are selected based on the shortest path techniques. The accessibility values of the routes are estimated based on the modified gravity and settlement interaction approaches. The selected links/routes are further evaluated by applying economic analysis, using the Road Economic Decision (RED) model, to determine the appropriate options for investment interventions. The methodology developed has been applied to Rajgarh Block of Churu district in Rajasthan as a case study by developing the database and analysis in GIS environment.
 
Findings and Conclusions
The integrated functional accessibility approach, suggested at block level, is useful for preparation of block level master plan for rural roads. The routes for connecting the unconnected villages are evaluated using the cost-effectiveness approach, i.e. access benefit-cost ratio as well as the cost benefit analysis for determining the needed investment interventions. Ranking of rural road projects can be carried out using this methodology.
