GIS, a tool for improving the road network management

Abstract

Transport is a significant branch of the economy due to its contribution to the creation of gross domestic product. In order to ensure a reliable transport network that boosts trade and economic growth, prior to the construction of new national roads and motorways, it is necessary to ensure a proper technical condition of the road. Therefore, road network administrators have to attain a balance between the program of maintenance / repair / rehabilitation activities and the works that can be executed within the limits of the available funds so that the investment achieves the highest profitability and the road network either viable. There are currently a number of factors that influence the decision-making process in prioritizing maintenance work as well as allocating funds so that the investment achieves the highest return. Therefore, a multi-criteria decision-making approach is needed to ensure a balance between the program of maintenance / repair / rehabilitation activities and the works that can be executed within the limits of available funds. In the present paper, the authors proposes to develop a decision support model based on the principles of the GIS information systems, to help the road network administrators to take decisions that prioritize the maintenance works.

Modeling Road Accessibility in a Flood-Prone Area in Romania

“…Initially, the databases were added and prepared for processing. The road network, the essential component used in the elaboration of this study, is line-type data, and comprises segments that have set travel speeds depending on the road quality [14]. Based on their length and speed, it was possible to calculate travel speeds on a road section in GIS [15].…”
