<title>Abstract</title> In this paper, a two-step approach for the evaluation of rail freight yard performance at a tactical management level, that could plausibly be used at both annual and weekly planning levels, is presented and discussed. The suggested approach involves analytical modelling with G/G/m...

<title>Abstract</title> The complex and uncertain nature of dealing with multimodal transport emissions generates a need for appropriate methodology to support informed decision making. This paper presents a system-of-systems (SoS) approach that takes into account the complexity of a policy problem stemming...

<title>Abstract</title> The institutional background against which air transport is supplied has been changing rapidly. The initiation of market forces has led to lower fares, additional services, and more efficient airline companies as competitive pressures have grown. A major concern, however, is whether the...

The increase in motor vehicle use is one of the important factors that cause traffic congestion, especially in megacities. Thus, the reasons behind this increase require serious attention. This paper offers an analysis of this kind, for a megacity from the developing world, Istanbul. A...

<title>Abstract</title> In response to an initiative to develop an advanced traffic information system in Bangkok, this paper explores practical guidelines for the optimal location of road sensors, such that the data collected on spot speeds reflect an entire link's average speed. In particular, the authors...

<title>Abstract</title> A framework for the evaluation of the effectiveness of traffic diversion strategies for non-recurrent congestion, based on predictive guidance and using dynamic traffic assignment, is presented. Predictive guidance is based on a short-term prediction of traffic conditions, incorporating...

<title>Abstract</title> Many urban university campuses are considered major trip attractors. Considering the multimodal and complex nature of university campus transportation planning and operation, this paper proposes a dynamic traffic simulation and assignment analysis approach and demonstrates how such a...

<title>Abstract</title> The need for dependable and flexible models of transit vehicle maintenance has been well established in the literature as a means for improving daily operations, capital planning and service quality. Stemming from the practical need to predict the duration of maintenance activities and...

This paper examines the variation in the value of travel time savings (VTTS) for travelers with a managed lane (ML) option when taking an ordinary trip versus a trip that is unusual in some way. VTTS estimates vary substantially depending on the urgency of the trip made. At the low end, the mean...

This paper proposes a solution to the problem of limited network sensor coverage caused by insufficient sample size of probe vehicles or inadequate numbers of fixed sensors. A framework is proposed to estimate link travel times using available data from neighbouring links. Two clues are used for...
