Impact of transport infrastructure on factors affecting traffic accidents in urban traffic: green supply chain issue

Abstract

This study aims to demonstrate the added value of the urban traffic control and its incorporation in the concept of Green in the Supply chain. We intend to consider the process of urban transport infrastructure and consider all infrastructural factors with a systemic perspective to examine the impact of these factors on minimizing the risk of urban accidents. The research data are gathered using questionnaires and interviews with experts in the field of traffic and transportation. In this research the effective factors in vehicle accidents were classified into four groups of Motive, Traffic function, Incident details and accident Prevention. Infrastructure components were also categorized into four categories that can be called the four sub-components: Roadways, Base preparations, Yards and stations and Development. Also, the priority of each component and their influence to each other are determined. According to research findings, improving transport infrastructure could reduce urban accidents and improve urban traffic.
