A System for Monitoring Environmental Quality of Urban Road Network and for Supporting Decision Makers

摘要

This paper presents the attempt to design and create a database system for monitoring the environmental quality of urban road network and for supporting the decision making process of local authorities. The factors that determine and affect the environmental quality of urban roads are researched and indices are designed to quantify these factors. These factors are categorized into 20 sub-categories and grouped into 8 main categories such as urban planning and architectural factors, traffic patterns, recorded roadside land uses, recorded road equipment, or even financial ones. On the whole, 124 indices are designed, and examined on a pre-selected part of the town of Chania, which is found to be characteristic for the urban complex. A geodatabase is created, which is based on the data that was collected for every index, and this geodatabase is directly connected with a Geographical Information System (GIS). Within this GIS the potential for processing, analyzing and presenting quantitative data, is examined. The aim of this geodatabase is to constitute a useful tool for the local authorities for a continual monitoring of the environmental quality of urban roads and in their decision making on issues concerning the management of the urban environment.
