In this report we present an ontology for Multi-Modal Transportation Planning and Scheduling. We take, as our starting point, the previously developed OZONE scheduling ontology, which provides a general basis for formulating scheduling domain models. We extend this core framework as necessary to capture the essential characteristics and constraints of multi-modal transportation planning and sch...

This paper concentrates on the dualistic role of transportation as a pro-active agent of globalization and as a beneficiary of its development. Surprisingly, transportation is possibly the least researched element in the complex of factors that foster a changing world economy. The goal is to suggest areas that require an informed social science perspective based on research that will enhance th...

We present the main freight transportation planning and management issues, brie y review the associated literature, describe a number of major developments, and identify trends and challenges. In order to keep the length of the paper within reasonable limits, we focus on long-haul, intercity, freight transportation. Optimization-based operations research methodologies are privileged. The paper ...

The ceaselessly increasing number of trips on urban highways and major arterial roads have caused serious congestion and air pollution problems. Thus many transportation agencies have persevered in their efforts not only to alleviate such problems, but also to minimize social costs. However, the complex nature of such problems has strongly hindered transportation agencies’ ability to consider a...

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 ...

The VASA project develops a multimodal assistive system mediated by a virtual agent that is intended to foster autonomy of communication and activity management in older people and people with disabilities. Assistive systems intended for these user groups have to take their individual vulnerabilities into account. A variety of psychic, emotional as well as behavioral conditions can manifest at ...

Introduction During this century several transportation modes, including transit, personal automobiles, and airplanes, have competed for market share. Despite this competition, the personal vehicle has become the dominant form of mobility in many countries throughout Europe and North America. In turn, public transit has found it increasingly difficult to attract and retain passengers. This pape...
