Ecological footprint (EF) determines the area of ecologically productive territory necessary to produce the resources utilised and to assimilate the waste produced by a given population over a year. Knowing your own EF is the first step in planning and implementing policies to reduce it. Considering that transport is a significant component of the impact of human activity on the environment, this study calculates the EF of the CO2 emissions associated with person mobility (EFM) at the University of A Coruña (UDC). The results presented are based on statistical inference from surveys conducted in 2008, 2016, and 2020. The period 2008–2016 coincides with the effects of the economic crisis, and 2020 with those of the COVID-19 pandemic. The EFM of UDC in 2016 was 2177 global hectares (gha), 148 times its biocapacity. Ninety-two percent of it was generated by car trips. Policies to reduce the environmental impact of mobility should focus on reducing car use. This study analyzes various factors of variability. The EFM per capita of the commutes from the place of residence to the UDC campuses grew between 2008 and 2020 by 17%. The results obtained are compared with those of other nearby universities and around the world.

The COVID–19 pandemic led to restrictions on activities and mobility in many parts of the world. After the main peak of the crisis, restrictions were gradually removed, returning to a new normal situation. This process has impacted urban mobility. The limited information on the new normal situation shows changes that can be permanent or reversible. The impact on the diverse urban transport modes varies. This study analyzes the changes in transit ridership by line, the use of stops, the main origin–destination flows, changes in transit supply, operation time, and reliability of the city bus network of A Coruña. It is based on data from automatic vehicle location, bus stop boarding, and smart card use. Data from the first half of 2020 were compared to similar data in 2017–2019, defining suitable baselines for each analysis to avoid seasonal and day of week effects. The impact on transit ridership during the lockdown process was more significant than that on general traffic. In the new normal situation, the general traffic and the shared bike system recovered a higher percentage of their previous use than the bus system. These impacts are not uniform across the bus network.

The availability of public databases provides a great amount of data for research, but their use can involve a lack of detailed information about the decision-makers. This fact prevents the analysis of systematic variations in their preferences. In addition, the influence of the explanatory variables included in the utility function of discrete choice models is not necessarily linear. The analysis of the port choice process through this kind of models has usually been addressed neglecting both the existence of heterogeneity in the preferences and the non-linearity in the variables. In this paper, a Box-Cox Mixed Logit Model is proposed to overcome both constraints, and it is introduced through a case study. In the aim to highlight the interest of the proposal made, the obtained results were compared with those of the more traditional formulations. The conclusion is that this model provides more accurate results. Therefore, it can better help policy-makers when assessing hypothetical scenarios to define their competitive strategies because conclusions can vary significantly, as can be seen from the prognosis carried out for the Spanish case.

Residential location choice (RLC) predicts where and how people choose their residential location in the framework of land use–transport interaction models (LUTI). This paper seeks an efficient RLC model in the context of irregular zoning of location alternatives. The main current proposals in the field are discrete choice models. In RLC modeling, the alternatives are spatial units, and spatially correlated logit (SCL) is an efficient approach when the analyst cannot pre-define groups of alternatives that efficiently reflect the systematic substitution patterns among the alternatives. The SCL uses the spatial information on the contiguity of the zones to determine spatial correlation among the alternatives. Urban residential location choice usually uses administrative zoning, which is very irregular in many cities (mainly historic cities); however, SCL is not efficient in this context owing to the limitations of the binary contiguity spatial variable employed as a spatial correlation metric (SCM). This paper proposes an extension of the mixed SCL model, with an SCM based on the proportion of common border length in contiguous zones, which is more efficient in the irregular urban zoning context. The proposed model is applied to an urban case study of LUTI RLC modeling with irregular zoning, based on the administrative divisions of the city of Santander (Spain) and is shown to be empirically more efficient than the previous approaches.

The aim of this study is to analyse how the degree of use of port facilities influences the port choice process. In order to achieve that goal, a multinomial logit model was firstly proposed and then applied to a case study. In this particular case, the relationship between the container traffic and the availability of cranes was considered for the main Spanish peninsular container ports. From the obtained results, it can be concluded that the port throughput contributes positively to attract traffic because of the economies of agglomeration and the scale and network effects achieved; however, there is a threshold of traffic beyond which the attractiveness of ports decreases. The proposed methodological approach also allows to obtain the functional form of the analysed relationship without establishing it a

A la hora de realizar una inversión en un nuevo sistema de capacidad intermedia (SCI) en el campo del transporte público urbano y metropolitano, en muchas ocasiones la elección de implantar un metro ligero se ha justificado en una percepción, bastante generalizada, de que los sistemas ferroviarios tenían mayor potencial de captación de viajeros que sistemas equivalentes basados en autobuses. Esto es lo que se ha venido a denominar como rail factor. En la investigación que se presenta se ha estudiado la existencia de este factor mediante una amplia campaña de encuestas de elección en preferencias reveladas y declaradas, desarrollada en ciudades españolas y francesas con distinta presencia de SCI. Tras la observación de más de 28 000 situaciones de elección, se han desarrollado modelos de comportamiento para las diferentes ciudades, empleando modelos logit multinomial, logit jerárquico y logit mixto. Además de variables explicativas tradicionalmente consideradas en el estudio del reparto modal, se han tenido en cuenta otros factores como la experiencia previa de los usuarios en el empleo del sistema de transporte público, la influencia de las elecciones reveladas en las elecciones declaradas o la calidad del servicio de transporte público. Se ha constatado que en algunos casos existía esa preferencia inherente por el metro ligero, pero que en otros la preferencia de los encuestados era por el autobús de alto nivel de servicio. Finalmente, se ha concluido que no puede afirmarse, de forma general, la existencia de un mayor potencial de captación por parte de los modos ferroviarios respecto a los basados en el autobús, siendo necesaria la realización de encuestas en las circunstancias locales para evaluar el potencial de captación real de cada caso particular.DOI: http://dx.doi.org/10.4995/CIT2016.2016.4067

Studies that link human behaviour to the influence of weather have historically been conducted in such fields as tourism, marketing and leisure. In most studies that jointly examine weather and the mode of transport, only open-air transportation has been considered (for example, bicycle, motorcycle or walking). This focus, together with the habitual use of data collected with automatic devices and a lack of studies that analyse this issue using stated preference data, are the main reasons motivating this paper. This paper aims to analyse the influence of weather and the density of traffic on the choice of transport mode. A case study is conducted in an access/egress corridor located in the city of Barcelona (Spain). Two data sources were used: revealed preference and stated preference data. Modelling techniques using mixed data enabled the stronger features from both data sources to be captured. Finally, we discuss how the selection of different alternative specific constants in models estimated using mixed data could generate unrealistic forecasting results if environmental changes are expected in the actual market.

This study identified and analyzed the reasons that have led the BusWay of Nantes, France, to be one of the most, if not the most outstanding and successful case of setting up a bus with high level of service (BHLS) system in European cities. The lessons and the conclusions from the study may be applicable to and useful for other sites with similar conditions. The analysis examined the measures that were implemented (infrastructure, vehicles, design of transit service operations, complementary facilities and services, and branding) and the results (level of service in frequencies and operating speed, reliability of schedules, ridership, and traffic safety). Furthermore, as BHLS and light rail transit (LRT) are integrated in the same level of the trunk network in Nantes, the city provided a relatively level playing field to develop an equitable comparison of the two systems. Through the case study of Nantes, the study found that the BHLS system was suitable for meeting demand volumes in the range from 1,000 to 2,500 passengers per hour in one of both directions during peak hours with a level and quality of service very near the LRT, but with more moderate investment costs and higher flexibility.

To represent the behavior of travelers when they are deciding how they are going to get to their destination, discrete choice models, based on the random utility theory, have become one of the most widely used tools. The field in which these models were developed was halfway between econometrics and transport engineering, although the latter now constitutes one of their principal areas of application. In the transport field, they have mainly been applied to mode choice, but also to the selection of destination, route, and other important decisions such as the vehicle ownership. In usual practice, the most frequently employed discrete choice models implement a fixed coefficient utility function that is linear in the parameters. The principal aim of this paper is to present the viability of specifying utility functions with random coefficients that are nonlinear in the parameters, in applications of discrete choice models to transport. Nonlinear specifications in the parameters were present in discrete choice theory at its outset, although they have seldom been used in practice until recently. The specification of random coefficients, however, began with the probit and the hedonic models in the 1970s, and, after a period of apparent little practical interest, has burgeoned into a field of intense activity in recent years with the new generation of mixed logit models. In this communication, we present a Box‐Cox mixed logit model, original of the authors. It includes the estimation of the Box‐Cox exponents in addition to the parameters of the random coefficients distribution. Probability of choose an alternative is an integral that will be calculated by simulation. The estimation of the model is carried out by maximizing the simulated log‐likelihood of a sample of observed individual choices between alternatives. The differences between the predictions yielded by models that are inconsistent with real behavior have been studied with simulation experiments.

Wear is a very important subject for railway administrations. Therefore, it would be of interest to develop a methodology for designing wheel profile geometry in order to improve its behaviour in relation to this subject. Until now, existing approaches of this kind are based on the statistical study of wear wheel profiles, but this do not consider the characteristics of vehicles and railway tracks, and in addition, it is not an option when a vehicle is going to run, for example, over two different types of track over which mixed running has not previously happened. In the current paper, a new general methodology is presented for improving wheel profiles in relation to certain physical phenomena that arise during the running of the vehicle over the tracks. This methodology is based on the genetic algorithm (GA) technique. To show the power of this procedure, it is applied to an application case (of a tram-train in Spain), in which great improvements in the behaviour of wheel profile are achieved. In the light of this application, the importance of definition of indexes which control the evolution of the GA is shown.

The provision of rural public transport has always been seen as a matter of competing for scarce public resources. The fundamental problem is that the demand for rural transport is low and the population is widely dispersed. Conventional public transportation solutions are not able to meet the demand efficiently. In this respect, railway transport proves to be particularly inefficient. In Spain there are approximately 2500 km of rural railway lines carrying low traffic volumes. These have traditionally been considered to be loss-making lines. Yet, in principle, this idea is incorrect. This paper looks at some of the techniques currently being successfully applied on rural railway lines that enable considerable savings on operational and maintenance costs to be made.

In response to the demand for improved mobility in metropolitan areas, the 1990s saw the development of a new transport system in Europe known as the tram-train. This system is based on using conventional railway lines with a low traffic density to extend urban tram (streetcar) or light rail services without changing vehicles, incorporating them into railway traffic. The tram-train enables a wider range and scope of direct transport services and reduces waiting and transfer time. The operation of light rail vehicles on conventional railway infrastructure requires the solution of numerous technical issues, such as traction power supply system, rolling stock design, gage compatibility, tire and rail profile, structural strength, passenger access, and signaling. Such problems are described and their solution by services now operating, or in advanced planning stages, worldwide is discussed.
