In this paper, we examine a vehicle routing problem with a makespan objective incorporating both stochastic and correlated travel times, which is usually not considered in routing problems. As an alternative to simulation, we develop an approach based on extreme-value theory to estimate the...

This paper outlines the rationale, methodologies, key findings and policy implications of the national Value of Travel Time Savings (VTTS) study conducted in Britain during 2014-15. The study found VTTS varied with distance, trip purpose and mode of travel but not with worthwhile use of travel...

This paper reports the theoretical and empirical evidence on the distributional effects of Express Lanes. It also provides evidence of how they affect congestion, both in the Express Lanes themselves and in the parallel general-purpose lanes. The paper also helps put Express Lanes in context by...

This paper discusses the importance of reducing the space consumption of car traffic as opposed to simply reducing individuals' travel time. It highlights the role of app-based mobility services in reducing urban congestion from a spatial perspective and the importance of shifting the focus from...

This paper explores the impact that advances in Information and Communication Technology (ICT) have on the behaviour of transport users and their mode choice habits in Seoul. It discusses the stated preference survey conducted in Seoul and the analysis carried out using the discrete choice...

Integrated interoperable rail systems facilitate high speed rail (HSR) train movement on conventional intercity lines, and vice versa. Hence, for such rail systems, it is preferred that HSR stations are located at existing intercity rail stations. However, all existing intercity stations may not...

Automated storage and retrieval systems (AS/RSs) are material handling systems that are frequently used in manufacturing and distribution centers. The modelling of the retrieval–travel time of an AS/RS (expected product delivery time) is practically important, because it allows us to evaluate...

In this paper we describe how we included travel time variability in the national Dutch transport forecasting model and what the policy impacts of this new forecasting tool are. Until now, travel time reliability improvements for road projects were included in Dutch cost-benefit analysis (CBA)...

This paper provides an overview of some alternative conceptual definitions of travel time variability, discusses their implications about behaviour, and puts them into a broader context, including deviations from the underlying assumptions regarding rational behaviour. The paper then discusses...

We present a new approach to shape functional urban areas in terms of proximity. It uses travel time from urban cores to connect them and to determine its hinterland. It only needs information that nowadays it is available for most countries. In addition, we test this approach to a developing...

This report revisits the rationale and methods for estimating the value of reductions in travel time. In doing so, it considers changes in the way people use time and specifically explores whether the value of time will fall towards zero as connected technologies allow a wide range of activities...

We study the trip scheduling preferences of train commuters in a real-life setting. The underlying data have been collected during large-scale peak avoidance experiment conducted in the Netherlands, in which participants could earn monetary rewards for traveling outside peak hours. The...

Regarding the location of a facility, the presumption in the widely used p-median model is that the customer opts for the shortest route to the nearest facility. However, this assumption is problematic on free markets since the customer is presumed to gravitate to a facility by the distance to...
