Non-linear modelling of urban road network accessibility

Abstract

Road network analysis is major vital aspects in moderating transport system capability. In most Indian cities, the rapidly expanding traffic demand has become difficult to handle due to existing road network.  The existing road network in most of the urban areas is facing the issues of proper connectivity, accessibility, maturity and development. In order to effectively use the existing road network, the most important network parameter, accessibility should be evaluated and modelled. Transport accessibility is generally a significant criterion of transport geography, as it represents the mobility of the people or goods in a particular location. High accessibility levels of a location imply that the location is well developing with fewer transportation-related problems.  A greater range of possible solutions to the problems related to transportation could be offered by accessibility-based planning and are preferred because accessibility is the eventual goal of most activities that include travelling.

In this context, the present study attempts to develop models for road network accessibility with respect to connectivity, maturity and development. The study aims to develop individual models with different independent variables and combined model for accessibility index using SPSS software. The present work also focuses on comparing the results of linear and non-linear models developed in the study. The models developed in the study are helpful for the urban transportation planners to balance the road network structure based on accessibility index.
