Sürdürülebilir ulaşım için yaşam döngüsü analizi uygulaması

In human life, transportation is one of the most important activities and needs. In terms of sustainable transportation, it is very important to select appropriate project for the least damage to the environment. The road superstructure needs to be renewed over time due to wearing caused by high load, climatic conditions, and improper construction materials. One or more lane or the entire lanes are generally closed during road renovation works. As a result, traffic flow conditions change and normal function of the road is deteriorated due to closed lanes. In this thesis, SIDRA Intersection analysis program and GaBi life cycle analysis software were used to determine the environmental effects caused by different lane changes during road renewal. In the scope of the study, entrance intersection of Mavişehir in İzmir was chosen as an example and it was accepted that 100 meters superstructure would be undergoing renovation works. Firstly, SIDRA program was calibrated by making observations at the signalized intersection. SIDRA program was then used to calculate the relevant fuel consumption in scenarios based on lane changes due to traffic emissions resulting from traffic delays and road renewal activities. Finally, life cycle analysis studies have been conducted for each scenario to determine the environmental impacts by considering both the materials to be used for road renewal and traffic delays. In life cycle impact analysis phase, eight different environmental impact categories were considered. The results obtained in the life cycle analysis were compared according to the scenarios produced for each impact category.
