The existing system for organizing and processing local car flows in railway junctions does not implement the concept of an integrated, or rather a systematic approach to ensuring interaction elements subsystems junction, as complex integral system, necessary extent. As result, local, at first glance, optimal measures further improve operation node do give expected effect. organization flows, d...

In the last years the interest in urban freight mobility has increased. However, the management and control of urban freight transport requires models which simulate the transport system. In literature some models have been analysed and implemented with tools which allow the verification of the measures adopted in several cities around the world. In paper a review of measures implemented in som...

The study examines the existence of liquidity risk premia on freight derivatives returns. The Amihud liquidity ratio and bid-ask spreads are utilized to assess the existence of liquidity premia. Other macroeconomic variables are used to control for market risk. Results indicate that liquidity risk is priced and both liquidity measures have a significant role in determining freight derivatives r...

Abstract: Here city logistics terminal is defined as the facility consisting of warehouse center, marketing center, freight detaching center, distributing center and the information center. It is a link of freight transport between transport terminal such as port, railway freight station and highway entrance and the retailing facilities. The purpose of this study is to optimize the size and spa...

The issue of shared use urban freight facilities first received attention during the 1970's when it was observed that, while inter-urban freight movements were becoming increasingly efficient, there were significant diseconomies in the movement of freight via truck within urban areas. Early research suggested that shared urban freight facilities should be constructed so that trucking companies ...

Data from freight traffic roadside surveys in Mexican highways are analyzed in order to find consistent patterns or systematic relationships between variables characterizing this traffic. Patterns traced are validated by contrasting against new data sets, allowing so a pattern’s description refinement. In a first stage truck traffic is characterized with respect to vehicle counting size, month ...

Air freight is an important part of the global supply chain. In particular, various high-value electronic products need to be transported efficiently by air freight. Currently, many air freight forwarders still rely on manual operations to process air cargo. These manual operations may affect target service levels due to handling delays and human errors, and result in high operational costs. In...

In freight consolidation, a “fair” cost allocation scheme is critical for forming and sustaining horizontal cooperation that leads to reduced transportation cost. We study a cost-sharing problem in a freight consolidation system with one consolidation center and a common destination. In particular, we design a mechanism that collects bids from a set of suppliers, and then decides whose demand t...

Rail wheel squeal on curves in rail track is a source of potential noise annoyance to residents adjacent to rail lines. For one private rail freight operator, wheel squeal was causing repeated complaints from neighbours. Wheel squeal can be caused by the wheel-tyre to rail-top interaction and the wheel flange interaction with the gauge face of the rail (more like a screech). This paper describe...
