A Methodology to Develop Hierarchial Road Network in Peri Urban Settlements: A case study in Chennai

Date of Start:July 2004
Division of Urban Systems Development, College of Engineering, Anna University, Chennai (R, I)

Scope and Objective
(i) To assess the existing accessibility level and road network pattern
(ii) To identify the level of infrastructure, activity pattern and travel characteristics of each settlement in the study area
(iii) To develop the hierarchial road network in order to establish the hierarchy in the accessibility level
(iv) To overlay the existing road network and proposed network and identify the missing links
(v) To assess the adequacy level of the existing network and establish a new hierarchy.

Methodology
(i) Identification of Study area
(ii) Data Collection – Primary Survey – Household Opinion survey and Secondary data – Census data such as Population, Non       Agricultural Workers, Agricultural workers, Literacy rate, Density etc. and Existing road network Map
(iii) Assessment of Level of infrastructure, Activity pattern and travel characteristics of each settlement.
(iv) Development of hierarchical road network using GIS based on Coplanar concurrent theory, Gravitational pull theory and       Moment principle theory.
(v) Overlay of Existing road network and proposed network and identifying the missing links.
(vi) Assessment of adequacy level of existing road network using EMME/2 and a new hierarchy is established.

Findings and Conclusions
A new hierarchy of road network is established for the study area. When new hierarchy is established it is seen that traffic gets uniformly distributed and congestion index is reduced.
