Port expansion and negative externalities: a willingness to accept approach
2015
Port expansion has been seen as the origin of negative externalities, affecting local residents’ well-being and contributing to the poor public image of ports. In this study, the contingent valuation method is used to estimate the costs borne by local residents as a consequence of the negative externalities derived from the growth of the Port of Valencia (Spain) in the last 30 years. As transport project appraisal has become more complex, this technique complements existing methodologies in this field, such as the social cost benefit analysis and the multicriteria analysis. Given the perceived property rights of families that have been living close to the port for a long time, a willingness…
The potential impact of Brexit on Ireland's demand for shipping services to continental Europe
2018
Abstract Ireland, as an island nation, has historically relied on the UK landbridge to export and import its goods to and from Europe. This provides a fast, reliable and secure service along the UK landbridge route relative to the more economical and less frequent direct continental route. However, the relative competitiveness of maritime services along both routes may be significantly influenced by the UK exit from the European Union or Brexit. This paper aims to understand the potential impact of Brexit on maritime freight transport demand from Ireland to continental Europe for export trade shipments. Based on data collected from an efficient stated preference (SP) experiment, discrete ch…
Measuring foreland container port connectivity disaggregated by destination markets: An index for Short Sea Shipping services in Spanish ports
2020
Abstract The present research aims to develop a Foreland Port Connectivity Index (FPCI) including both qualitative and quantitative variables related to the characteristics of the maritime services provided. To that end, the FPCI incorporates two discount factors—the number of shipping services and destination countries—as penalties to correct for the quality of a port connection. After defining the FPCI, the index is applied to Spanish ports to study their connectivity in terms of container Short Sea Shipping (SSS) services. Although the connectivity of SSS traffic has not been widely studied, it is an interesting case study as small ports play a more relevant role in facilitating access t…
Assessing cruise port of call performance: a passenger-based approach using PLS modelling
2017
ABSTRACTIn the present context of booming cruise demand, the study aims to advance the knowledge on port of call performance from cruise passengers’ perspective. The aim of this investigation was twofold: (1) to examine the structural links among port of call perceived quality–satisfaction–future intentions (revisit and word-of-mouth (WOM) behaviour); and (2) to test the moderating effect of cruisers’ motivation (push versus pull factors) to visit the port of call on the proposed structural links. Partial least squares path modelling was used to test the proposed model with a sample of 492 cruise passengers at a Mediterranean port of call. The findings revealed that port of call quality has…
Activity Report of the French Transport Geographers
2007
International audience; The 2007 Répertoire des Géographes Français shows 97 geographers (on a total of 2084 listed people) working in the transportation field. The Commission de Géographie des Transports meets every year in mid-September for a thematic conference: Cergy-Pontoise in 2004 (transportation nodes), Besançon in 2005 (inter-regional transportation networks), Chambéry in 2006 (tourism and transportation, co- organized with the Commission de Géographie du Tourisme). In addition, the main theme of the 2005 Festival de Géographie in Saint Dié-des-Vosges, "World in networks", allowed many transportation geographers to present their research to a wide audience reaching outside of acade…
Application of queuing methodology to analyze congestion: A case study of the Manila International Container Terminal, Philippines
2016
The objective of this paper is to apply queuing methodology in order to analyze congestion at the Manila International Container Terminal (MICT) in the Port of Manila, the Philippines. The vessels calling at the MICT have to wait in a queue before receiving services at berths because of congestion. For vessel operators and cargo owners this situation creates waiting time costs and delays in delivery of goods to final customers. One option to decrease waiting time is to expand capacity by increasing the number of berths. Construction of a new berth is a time consuming and costly procedure, which needs to be considered carefully before being implemented. To determine whether the data collecte…
Schedule-Based Integrated Intercity Bus Line Planning via Branch-and-Cut
2018
This work addresses integrated line planning for intercity bus lines, which differs in several respects from line planning in public transit. Passengers in intercity transportation decide on specific timetabled services to get to their destination. This is a contrast to an urban setting with higher frequencies, where it is generally sufficient to choose a line. Furthermore, intercity bus transportation in deregulated markets is usually characterized by fierce competition within and across modes. Customers are highly sensitive to price, time of day, duration, convenient access to stations, and service quality. Hence, bus line operators need to decide thoroughly on every single timetabled se…
Branch-and-price-and-cut for a service network design and hub location problem
2015
In the context of combined road-rail freight transport, we study the integrated tactical planning of hub locations and the design of a frequency service network. We consider a number of real-world constraints such as multiple transshipments of requests at hubs, transport time limits for requests, request splitting, and outsourcing possibilities. To our knowledge, the combination of problem features we deal with has not been described before. We present a path-based model and solve it with a branch-and-price-and-cut algorithm. Computational experiments show that large realistic instances from a major German rail freight company can be solved close to optimality within one hour on a standard …
A GIS-Based Methodology to Estimate the Potential Demand of an Integrated Transport System
2017
In the design of a new public transport system or of an extension of an existing system, the choice of a suitable placement of stations and stops in the territory and the definition of the main axes are very important. The different choice in the number and distribution of the stops of a road transport system or of a railway transport system, in fact, makes the system more or less widespread and affects the consistency of the catchment area and the attractiveness of the system. The accessibility of a system, add to the reliability in providing the service, is the fundamental parameter influencing the modal split of the users. Therefore, the Public Administration must have tools able to eval…
Investigation of the consequences of the modifiable areal unit problem in macroscopic traffic safety analysis: A case study accounting for scale and …
2019
Abstract Traffic safety analysis at the macroscopic level usually relies on previously defined areal traffic analysis zones (TAZs) that are used as the units of investigation. Hence, statistical inference is made on the basis of such units, implying that the consideration of a certain TAZ configuration may influence the results and conclusions achieved. Regarding this, the modifiable areal unit problem (MAUP) is a well-known issue in the field of spatial statistics, which refers to the effects that arise in statistical properties and estimations when there is a change in areal units of analysis. In this paper, the consequences of MAUP have been investigated through a dataset of traffic cras…
