A sustainable transportation system has been defined as “one that satisfies current transport and mobility needs without compromising the ability of future generations to meet their own” (Black, 1997; Richardson, 1999). The success of sustainable transportation in urban regions depends on encouragement of non-motorized (pedestrian and cyclist) and sharedride transportation modes instead of car-...
Resilience has been discussed in ecology for over forty years. While some aspects of resilience have received attention in transport planning, there is no unified definition of resilience in transportation. To define resilience in transportation, I trace back to the origin of resilience in ecology with a view of revealing the essence of resilience thinking and its relevance to transport plannin...
Sustainability Background Sustainability is a broad term that considers the environmental, social, and economic aspects of problems and their respective solutions. Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs. (Brundtland 1987) Physical, economic and social patterns of human developm...
Recently, sustainability has become a very important research area in transportation because of the dependencies between transportation, economic, and environmental systems. A great deal of research is being conducted regarding various aspects in order to try to understand these interdependencies. However, still there is a need to capture the behavior of such systems over time. This study attem...
Abstract The role of transportation in the economic process is central. Transportation’s benefits, however, can be dampened because its environmental and social cost. A central question then arises as to degre sustainability a national system. In present paper we develop mathematical model define assess sustainability. relies on number indicators encompassing impact, efficiency, safety, contrib...
This paper focuses on the procurement of full truck-load transportation service with the view to ensuring sustainability in transport logistics. The carrier assignment problem (CAP) involved in truck load contract auction is studied using a complete enumeration method and heuristic approach. Performance of both methods is compared in terms of solution quality and computational time based on the...
Sustainability throughout supply chains is gaining more importance and re-planning inventory operations can help companies curb emissions. In this study, we present two bi-objective integrated continuous review inventory control and transportation models with less-than-truckload and truckload carriers. Solution methods to approximate the Pareto Frontiers are proposed. Numerical studies illustra...
