Transportation diversity (also called options, choice and multi-modalims) refers to the quantity and quality of transportation options available in a particular situation. It includes different modes, services and prices. Increased transport diversity can provide numerous benefits, including increased transport system efficiency, consumer savings, and support for equity objectives. Many of thes...

Existing studies on transportation mode detection from global positioning system (GPS) trajectories mainly adopt handcrafted features. These features require researchers with a professional background and do not always work well because of the complexity of traffic behavior. To address these issues, we propose a model using a sparse autoencoder to extract point-level deep features from point-le...

Mr. Chairmen and Members: We are pleased to be here today to discuss challenges in defining the federal role with respect to freight transportation issues. There are concerns that the projected increases in freight tonnage for all transportation modes will place pressures on the marine, aviation, and highway transportation systems. As a result, there is growing awareness of the need to view var...

Recognition of transportation modes can be used in different applications including human behavior research, transport management and traffic control. Previous work on transportation mode recognition has often relied on using multiple sensors or matching Geographic Information System (GIS) information, which is not possible in many cases. In this paper, an approach based on ensemble learning is...

In this work, we employ the GVAR model in order to analyze demand aspects of a multimodal public transportation system. The methodology is applied to the Athens region, Greece. GVAR provides a relevant econometric modelling framework for assessing relationships between economic entities, such as transportation modes, by analyzing the relative shocks and channels of transmission mechanisms among...

This paper studies the possible integration of long-haul operations by transportation mode and service level (defined by guaranteed delivery time) for package delivery carriers. Specifically, we consider the allocation of deferred items to excess capacity on alternative modes in ways that allow all transportation modes to be utilized better. Model formulation and solution techniques are discuss...

Most transportation-related applications are developed for privately-owned cars. Some recent ones are devoted to public transportation, they show limitations in dealing with the following aspects: (i) people who use public transportation may change transportation means not only within the same type but also among different modes such as between buses and subways and (ii) the system should take ...

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-...

In recent years, comprehensive researches have provided ample support for the supply chains in the coordinated decision-making framework. However, the issue of closed-loop supply chain coordination considering various transportation modes has not yet been addressed in the literature. In this paper, a two-echelon closed-loop supply chain consisting of a manufacturer and a retailer is investigate...

Energy issues in transportation systems have garnered increasing attention in recent years in both the public and private sectors. This study proposes a systematic methodology for policy-makers to improve energy consumption efficiency in multimodal intercity transportation systems considering suppliers’ operational constraints and travelers’ mobility requirements. A bi-level optimization model ...
