Air transport industry has gradually increased its share of global passenger and freight traffic, and this trend has accelerated in the last 40 years. For the past decade, air-freight traffic growth has outpaced air passenger traffic growth by 1-2% each year. In the past, air-freight sector offered limited services, with heavy reliance on several intermediaries and a significant dependence on a...

Introduction Common practices in current urban logistics planning in Scandinavia and the UK, and the degree to which SUTP (Sustainable Urban Transport Plan), SUMP (Sustainable Urban Mobility Plans) and SULP (Sustainable Urban Logistics Plans) guidelines are used, are examined in this paper. Methods A systematic literature review identifies relevant studies based on predefined inclusion criteria...

This paper investigates the determinants of freight rates between six European countries and 47 partners. We show that the inward freight rates are, on average, 23% higher than for outward ones, indicating that the cost of repositioning empty containers is mainly carried by European importers. Moreover, we have broken down the freight rates into basic ocean freight and surcharges in order to an...

Purpose. This study is aimed at determining the vertical dynamics of supporting structures freight cars made round pipes. Methodology. Mathematical modeling dynamic loading main types pipes (gondola car, covered flat hopper car) was carried out. The studies were out in a plane coordinate system – XZ plane. At same time, it taken into account that car moving an elastic-viscous track so reactions...

This paper proposes a micro-simulation model for urban freight movement, in which the behavior of freight agents and their relationship in supply chains are incorporated. The proposed model is a modification of the traditional four-step approach in that it considers the behavior of each freight agent individually. This paper covers three of the four steps of the traditional approach, including ...

Considerably less research has been done on modeling freight demand with disaggregate discrete models than on modeling passenger demand. The principal reason for this imbalance is the lack of freight demand data. Freight demand characteristics are expensive to obtain and are sometimes confidential. This paper analyzes the freight demand characteristics that drive modal choice by means of a larg...

We analyse maintenance cost data for Swedish railway infrastructure in relation to traffic volumes and other characteristics, and separate the cost impact from passenger and freight trains. Lines with mixed passenger and freight traffic, and dedicated freight lines are analysed separately using both log-linear and Box-Cox regression models. We find that for mixed lines, the Box-Cox specificatio...
