Location of logistics companies: a stated preference study to disentangle the impact of accessibility

Due to the globalization and the fragmentation of industrial production processes, the logistics sector, organizing the linkages between different production plants and the market, is growing fast. This results in an increasing demand for suitable new business locations. Previous research has indicated that accessibility is a key factor in the location decision making process. Though the literature on this subject is extensive, little research has been done to quantify the impact of the different dimensions of accessibility on the location decision process of logistics companies. This paper aims to fill this void in the literature by means of a revealed preference study (using a Geographic Information System (GIS) analysis) and a stated preference study (using a designed discrete choice experiment) in Flanders (Belgium). The results of the revealed preference study served as input to the design of the choice situations in the stated preference study. In the stated preference study, the respondents were confronted with a series of choice situations described by means of accessibility variables as well as land rent information. An analysis of the resulting data by means of discrete choice modeling revealed that land rent is the most important factor in the location choice of logistics companies in Flanders. Access to a port is the second most important factor, followed by access to a motorway, the location in a business park and an inland navigation terminal, which are all about equally important. Access to a rail terminal plays no significant role in the location choice of logistics companies in Flanders.     

Institutional integration for sustainable transportation policy in Canada

In recent years, many Canadian urban areas have witnessed a rapid population and economic growth thereby putting sustainable transport and urban form at the forefront of planning initiatives. As a result, the development of strategic transport plans and long-range visioning exercises has become a priority for most cities. Still, proper appraisals of these plans along with funding and implementation have lagged behind. Reasons for this lag can be attributed to the lack of constructive interactions between actors in the decision-making process and of common grounds for policy evaluation. This paper proposes to assess the extent of institutional integration in the appraisal, funding, and implementation of transport policy. For this purpose, a survey was conducted with planners and policy-makers pertaining to the three levels of government (municipal, provincial, federal) in Canada. The survey discussed the existing process for funding and evaluation of transport policy and its associated pitfalls as well as the desired state of policy appraisal. Results show low institutional integration among the three levels of government and weakened regional visions within most urban areas in spite of an increased sensitization of decision-makers and the public regarding the importance of achieving society's goals of sustainability and equity.     

Integration of HSR and air transport: Understanding passengers’ preferences

Different solutions for the integration of high-speed rail (HSR) and air transport could be implemented, ranging from very basic integration to more sophisticated systems which include ticket and handling integration. A discrete choice experiment is conducted to better understand passengers’ preferences. We estimate a number of flexible choice models, taking into account the existence of systematic and random taste heterogeneity. We obtain a range of willingness-to-pay values for service quality attributes, finding some important results that can be used to infer policy conclusions about the real attractiveness of the Air–HSR integrated alternative. In this respect, we find that schedule coordination which reduces connecting time will be crucial.     

An evaluation of the transport to employment (T2E) scheme in Highland Scotland using social return on investment (SROI)

This paper presents findings from an evaluation of transport to employment (T2E) in rural Highland Scotland. T2E is a centrally co-ordinated shared transport service which provides access to workplace, training and childcare where no alternative transport is available. The paper assesses the social as well as economic impacts on the local community through social return on investment (SROI) analysis. Measurable social benefits were found to outweigh the investment by 3:1 suggesting the concept to be a viable solution in a climate where public transport options are limited and typically restricted by low density and dispersed populations and challenging conditions for delivery.     

Evaluating the European added value of TEN-T projects: a methodological proposal based on spatial spillovers, accessibility and GIS

This paper develops a methodology for calculating the European value added value (EVA) generated by transport infrastructure projects. This approach is particularly useful for evaluating projects in the framework of Trans-European Transport Networks (TEN-T), although it may also be used in trans-national projects in other geographical areas. The methodology is based on the appraisal of spatial spillovers generated by trans-national projects by using accessibility indicators (access to markets) and Geographical Information Systems (GIS). Projects are split into sections and spillover effects of each section are then computed. The sections that produce a high proportion of spillovers in relation to internal benefits generate a high EVA. Additionally, indicators are obtained of the effects of each section in terms of spatial concentration on the different countries affected, efficiency (general improvement in accessibility) and territorial cohesion (reduction in accessibility disparities between regions). The validity of this approach is verified by applying it to TEN-T priority project 25. This methodology does not seek to replace existing project appraisal methodologies (particularly the cost-benefit analysis); rather it provides complementary data for decision-making. Sections which are scarcely profitable from the cost-benefit analysis perspective but which have high European value added should receive more European funding than more profitable sections of markedly national interest.     

Exchange rates and US direct investment into Latin America

Abstract

In this paper, we analyze separately the determinants of maritime transport and road transport costs for Spanish exports to Poland and Turkey (markets for which maritime and road transport are competing modes) and investigate the different effects of these costs on international trade. First, we investigate the extent to which maritime and road transport costs depend on different factors such as unit values, distances, transport conditions, service structures, and service quality. Second, we analyze the relative importance of road and maritime transport costs in comparison with distance measures as determinants of trade flows. The main results of this investigation indicate that real distance is not a good proxy for transportation costs and identify the central variables influencing road and maritime transportation costs: for both modes, transport conditions are strong determinants, whereas efficiency and service quality are more important for maritime transport costs, and geographical distance is more important for road transport. Road and maritime transport costs are central explanatory factors of exports and they seem to deter trade to a greater extent than road or maritime transit time when endogeneity is considered.     

Gasoline prices,transport costs,and the U.S. business cycles

The effects of gasoline prices on the U.S. business cycles are investigated. In order to distinguish between gasoline supply and gasoline demand shocks, the price of gasoline is endogenously determined through a transportation sector that uses gasoline as an input of production. The model is estimated for the U.S. economy using five macroeconomic time series, including data on transport costs and gasoline prices. The results show that although standard shocks in the literature (e.g., technology shocks, monetary policy shocks) have significant effects on the U.S. business cycles in the long run, gasoline supply and demand shocks play an important role in the short run.

The construction of a HSR network using a ranking methodology to prioritise corridors

The construction of new high-speed rail (HSR) lines, in a climate of financial instability since the onset of the global crisis of 2007–2008, has reopened the debate among the scientific community. Support for the new projects is facing serious concerns over the extremely elevated costs of high-speed and the ability of today's governments to fund or co-fund these systems. This is the main reason the assessment of methodologies to prioritise the construction of new high-speed rail (HSR) corridors has recently become an important issue for transport planners in countries like the U.S. where HSR does not exist.The literature on ranking tools for prioritising HSR corridors is practically non-existent, even in Europe. In 2009, a new ranking methodology was developed and applied to 30,000 city pairs in the U.S. to determine their suitability for high-speed rail investment. As none of these lines has been constructed and none of them are in operation, this methodology has not been validated. The main objective of this paper is to analyse, validate and improve this ranking tool using data from a current HSR network: the Spanish one. Results show the consistency of the model as a preliminary approach to ranking pairs, mainly for the top first O–D relations; however the model fails to discriminate clearly between secondary groups of corridors. These deficiencies are chiefly due to the type of variables used by the model which ultimately, after improved, would provide policymakers with a useful tool when planning the construction of a new HSR network.
