City logistics aims to improve urban freight transportation by considering the costs and benefits of public and private sectors, consolidating segmented freight shipments, and integrating the individual actors in a collaborative environment. This thesis studies network design problems in city logistics systems to address managerial challenges in urban freight transportation. We consider two network design schemes, namely the one and the two-echelon distribution networks, to formulate strategic and tactical level problems in urban freight transportation. In the single-echelon systems, freight is distributed from consolidation centers located on city boundaries to the customers inside the city. In the two-echelon systems, goods are unloaded at the intermediate facilities, called satellites, and consolidated into smaller vehicles suitable for the last-mile delivery in city centers. From an operational level perspective, we highlight the importance of synchronizing first and second echelon vehicles at the satellite locations and discuss the relation of the satellite synchronization problem to the network design problems. We propose mathematical programming formulations for the introduced strategic, tactical, and operational level problems in city logistics, and develop exact and heuristic solution approaches. The exact approaches use column generation to find optimal delivery routes efficiently. The heuristics are based on the hierarchical decomposition of the original problem into its basic decisions. Extensive computational studies in this thesis provide new insights into designing and implementing a practical city logistics system in real-world.

Freight villages: A literature review from the sustainability and societal equity perspective Baydar, A. Mete; Süral, Haldun; ÇELİK, MELİH (2017-11-20) The purpose of this study is to present a state-of-the-art literature review on Freight Villages from the sustainability and equity perspective, and discuss their impacts and place in the supply chain and logistics networks while focusing on the core concepts of freight transportation. With an understanding of the structure of freight villages, it is clear that they have potential for a number of merits with the increase in freight transportation activities. However, our review shows that current literature...
Spatial analysis of two-wheeled vehicles traffic crashes: Osmaniye in Turkey YALÇIN, GÜLER; Düzgün, Hafize Şebnem (2015-11-01) To achieve a sustainable traffic management and sustainable transportation planning in urban areas one of the tools that can be used effectively is Geographic Information Systems. In Turkey Transportation Department under Civil Engineering deals with roads and railways which are open to public such as inner city and outer city traffic arrangements with General Directorate of Security. This paper aims to analyze road traffic accident distribution according to the vehicle types involved in the accidents for u...
Sustainability of urban regeneration in Turkey: Assessing the performance of the North Ankara Urban Regeneration Project Korkmaz, Cansu; Balaban, Osman (Elsevier BV, 2020-01-01) The increasing environmental footprints of cities necessitated the integration sustainability principles into urban planning and development frameworks. The growing attention on urban sustainability also influenced the policy and the practice of urban regeneration. The quest for new methods for regenerating existing urban quarters in sustainable manners resulted in the concept of sustainable urban regeneration. The concept aims to develop urban regeneration projects in line with the three key pillars of sus...
Public transport improvement policies : assessment of the role of route and fare integration, modal reorganization with special emphasis to İzmir case Öncü, Mevlüde Ayça; Babalık, Ela; Department of Urban Policy Planning and Local Governments (2007) Public transport improvement and new public transport management approaches are accepted as the most effective tools in order to cope with the urban transportation problem threatening sustainable urban life and efficient functioning of urban areas. The need for new solutions to replace, or support, costly new capacities created two new concepts at the two ends of the transportation phenomenon; Travel Demand Management (TDM) on the demand side and Transportation System Management (TSM) at the supply side. Th...
Mobility-on-demand scenarios relying on lightweight autonomous and connected vehicles for large pedestrian areas and intermodal hubs Kumru, Murat; Makarem, Laleh; Gillet, Dens (null; 2017-10-05) This paper presents Mobility-On-Demand (MoD) scenarios relying on lightweight autonomous and connected vehicles to ease commuting in large pedestrian areas and intermodal hubs. In particular, we discuss the case of the EPFL campus as an example of a large pedestrian area and the case of the main Zurich train station as an example of a large intermodal hub. These two scenarios help to investigate the potential benefits and the implementation challenges of innovative lightweight autonomous and connected vehic...
