    Urban Freight is vital for the economic, social and cultural growth of the city. The multiplicity of stakeholders and conflicting interests confer magnified difficulty in cities and in all centers of European cities. Future Smart cities, sensorized and with real-time data, will streamline the management of the Smart city logistics. Information infrastructure becomes an indispensable asset to society, contributing to the development of info-ecosystems covering smart mobility and logistics last step (the "last mile" or the capillary distribution). This article analyzes the current situation of urban freight distribution in European cities, the usual measures of implementation, the stakeholders and their positions, and some of the current trends and practices that confer the Smart city logistics one area of growing interest from the scientific point of view as well as from the professional application perspective.

    This paper presents a reformulation of the hybrid model developed by Daganzo (2010) to extend its applicability to a greater number of cities, especially those characterized by a radial street pattern. The new transit network structure is also composed of two types of schemes: radial/circular in the central area and hub and spoke in the periphery. This analytical model defines the optimal network layout through minimizing its objective function, which is composed of agency and user costs. Its decision variables are central area size, headway, line spacing, and stop spacing. In this reformulation, stops with single coverage, those only served by one line, are introduced in the hybrid model to improve spatial accessibility to avoid an increase in agency investment. This model is a tool to design competitive transit systems topologically characterized by simple schemes adapted to the urban structure and concentrated transit flows, and also operatively by high frequencies and speeds. Ultimately, all this allows for easy use and management of transit networks. The model¿s robustness with regard to input parameters and decision variables reinforces its results and estimates what implementations on real road networks would be like. It presents coherent behavior regarding real-world standards, where high, concentrated and temporally well distributed demands lead to more efficient and effective transit systems. High performance bus (HPB) is the transport technology used throughout this paper because, as has been proved in this paper, it is the best transit mode in urban areas for a wide range of demand values. Main system characteristics have been obtained such as central areas greater than a 25% of the city, low headways of around 2 min, high commercial speeds ranges between 14 and 17 km/h, and suitable spatial accessibility, where stop spacing moves between 350 and 550 m.

    We present a strategy to improve bus service in urban networks that gives equal or better transit service and saves public resources: a win-win strategy. It consists on changing from ¿direct lines¿ to mobility centers from each quarter of the city to a bidimensional ¿network structure¿ and from ¿schedule based¿ management to ¿frequency based¿ management. The implementation in Lleida, a 140,000 inhabitant city of Spain, has proven that it is possible to save 15% of the resources providing equal or better door-to-door service, but a final fine-tuning has found the proper equilibrium between ¿network structure¿ and ¿direct lines¿ to better fit the users¿ perception.

    This paper shows that the precision of a freeway travel-time information system, in a real-time context, is not related solely to the accuracy of the measurement. Immediacy in reporting the information and forecasting capabilities play a role. Therefore, focusing only on the accuracy of the travel-time measurement is a myopic approach, which can lead to counterintuitive results. Specifically, it is claimed that, using travel times estimated with the traditional spot-speed midpoint algorithm, the performance of the real-time information system when evolving traffic conditions prevail is better than using much more accurate directly measured travel times (MTTs). Guidelines for an adequate configuration of the common parameters of the system are provided. In addition, real-time context enhancements for travel-time estimation methods based on punctual speed measurements are proposed. These are addressed by taking into account an easy and practical implementation. They have been proven to work well in an empirical application on a Spanish freeway.

    La congestió del trànsit és la principal font d¿ineficiències en les autopistes metropolitanes (pèrdua de productivitat, d'energia o emissió de gasos contaminants, entre d'altres externalitats). Les estratègies de gestió activa del trànsit (ATM, en anglès) s¿utilitzen amb la finalitat d¿afrontar el problema i alleujar els seus efectes, mitjançant la gestió de la congestió, tant recurrent com no recurrent, amb una combinació d¿estratègies operacionals en temps real i de predicció.La gestió dinàmica del límit de velocitat (DSL, en anglès) és una eina d¿ATM que pretén aportar certs beneficis al trànsit de les autopistes, com l¿increment de la capacitat i/o l¿homogeneïtzació de les velocitats dels vehicles. Actualment, està implantat en moltes autopistes metropolitanes d¿arreu del món. Aquesta tesi està dedicada a avaluar aquests avantatges conceptuals amb dades empíriques i models contrastats de flux de trànsit.Les dades empíriques s¿obtenen de l¿autopista C-32 a Barcelona, la primera instal·lació de DSL a Espanya. L¿anàlisi detallat d'aquestes dades permet la caracterització dels efectes de l¿estratègia de DSL en el comportament del trànsit. S'ha trobat que, sota les condicions adequades, el DSL pot augmentar la capacitat de les autopistes a causa d'una reducció en la dispersió de les velocitats entre carrils. Aquesta contribució permet definir noves polítiques d¿ATM.Es proposa una estratègia coordinada per a la gestió del trànsit que té en compte tant les estratègies de control d¿accessos com de DSL, per tal de reduir el fenomen de la pèrdua de capacitat en les proximitats d¿una rampa d¿accés en autopista. L¿eficàcia d¿aquesta estratègia de gestió s¿avalua amb simulacions, mitjançant una extensió del model tradicional de transmissió per cel·les, que incorpora la capacitat de reproduir estratègies DSL, juntament amb la pèrdua de capacitat. Els resultats mostren una millora en els indicadors de rendiment del sistema, destacant els beneficis en termes d¿equitat que l¿estratègia coordinada aporta .Finalment, els resultats d¿un anàlisi cost-benefici de l¿estratègia DSL, considerant els principals factors externs, suggereixen que la rendibilitat social d'aquesta estratègia en autopistes metropolitanes, quan s'aplica de forma aïllada, és limitada. Les potencials sinergies derivades de l¿aplicació coordinada d¿un conjunt d¿estratègies ATM, defineixen un interessant repte per a futures investigacions.

    Traffic congestion is a major source of inefficiencies in metropolitan freeways (e.g. productivity loss, energy waste, pollutant emissions, among other externalities). Active traffic management (ATM) strategies are used in order to face the problem and alleviate its effects by managing recurrent and non-recurrent congestion with a combination of real-time and predictive operational strategies. Dynamic speed limit management (DSL) is an ATM tool believed to bring some benefits to freeway traffic, like the increase in capacity and/or the vehicle' speed homogenization. Currently it is being implemented in many metropolitan freeways worldwide. This thesis is devoted to assess such conceptual benefits with empirical data and robust traffic flow models. Empirical data are obtained from the C-32 freeway in Barcelona, the first DSL implementation in Spain. The detailed analysis of these data allows characterizing the effects of DSL management on traffic behavior. It is found that, under the right conditions, DSL can increase capacity due to a reduction in the speed dispersion across lanes. This finding allows defining new ATM policies. A coordinated strategy for traffic management considering both ramp metering and DSL is proposed in order to reduce the capacity drop phenomenon in the vicinity of a freeway on-ramp. The effectiveness of this control method is tested using simulation with an extension of the traditional cell transmission model, which incorporates the ability to reproduce DSL, together with the capacity drop. Results show amelioration in the performance indicators of the system, highlighting the equity-friendly component of this coordinated strategy. Finally, results from a cost-benefit assessment of DSL considering the main externalities suggest that the social profitability of DSL management in metropolitan freeways is limited when applied alone. The potential synergies of applying a ¿pack¿ of different ATM strategies in a coordinated way, define challenging issues for further research.

    This paper analyzes in a systemic way a taxonomy of technologies that allow “continuous charging” (ConCha) of vehicles while they circulate on highways. Once the menu of available technologies has been described, they are appraised following a multi-criteria method to select the most promising one. This happens to be the Induction Power Transfer system, also called OLEV for on-line electric vehicle, and already in laboratory implementation in Korea. After the description of the system a cost-benefit analysis is performed and applied to a highway in Barcelona, Spain. The conclusion is that the system is already feasible nowadays and it can be even more feasible in the near future, depending upon the vehicle technology cost and energy price.

    This paper examines the design of high performance transit network that minimizes the transit agency costs, the time of transit users in the system and the travel time of car users. Surface transit services need segregated lanes to achieve a target cruising speed, so that the transit network length has a significant impact on the traffic performance. This effect has been modeled in this paper by the Macroscopic Fundamental Diagram (MFD). The optimization process encompasses two different approaches. First, an analytic model defines the optimal layout of surface transit networks according to the time headway, stop spacing, line spacing and network size variables. Then, the average travel time of the traffic network is evaluated by the use of the MFD curve corresponding to the former transit network length. The full methodology has been implemented in the city of Barcelona. The calibration of MFD in its central district has been done by means of traffic microsimulation runs. The social optimum number of corridors is 15, somewhat smaller than the optimization which does not consider traffic (23).

    El presente trabajo trata la optimización del diseño de redes de autobús de altas prestaciones teniendo en cuenta los costes de los usuarios y el operador del bus junto con los costes del vehículo privado. Investigaciones recientes (Daganzo 2010, Estrada et al. 2011) formulan las prestaciones de los usuarios y los costes del operador de una red de altas prestaciones en ciudades compactas. Dichas prestaciones se consiguen segregando las líneas de transporte público, utilizando buses de alta capacidad, mayor espaciamiento entre paradas y con intervalos de paso bajos en hora punta. La implementación de la red de autobuses genera una disminución del espacio viario disponible para el vehículo privado que conllevará el incremento de los tiempos de viaje de la red vial. En consecuencia, en el presente trabajo se incluye el coste asociado al vehículo privado dentro de la función objetivo de costes. Dicho coste se formula a partir del diagrama fundamental macroscópico (Geroliminis y Daganzo, 2008) que se considera variable según el número de corredores de la red de altas prestaciones. En su aplicación a la ciudad de Barcelona, la inclusión del vehículo privado en la función objetivo resulta en una red óptima de 15 corredores de altas prestaciones. Este valor se sitúa entre el valor óptimo sin restricciones de 23 corredores presentado por Estrada et al. (2011) y los 11 corredores propuestos por la administración pensados para no afectar en exceso al vehículo privado.

    In one of the very first papers on traffic flow theory back in 1952, Wardrop presented the difference between the space mean speed (SMS) and the time mean speed (TMS) of a group of traveling vehicles, and derived a relationship suitable for estimating TMS, given SMS and the speed variance over SMS. As time goes by, traffic practitioners have tended towards computing TMS instead of SMS, mainly when using double loop detectors, and nowadays this is the usual practice in traffic management centers. Therefore, the useful relationship between TMS and SMS should go the other way around in relation to Wardrop’s. Recently, the complementary relationship, suitable for estimating SMS from TMS and the speed variance over TMS, has been proved. However this is not enough, as speed variance is usually not available. The present paper develops a probabilistic method to estimate SMS from TMS without the previous knowledge of speed variance and only using the usual time aggregations of double loop detector data. The main assumption of the method – the normality of vehicle speed distribution – is discussed and a formulation to obtain the expected error of the estimation is derived. The results obtained with test data from the AP-7 highway, near Barcelona in Spain, show that the developed methodology is able to estimate SMS with an average relative error as low as 0.5%.

    Bus stops represent a key bottleneck that produces significant delays in travel times. In major cities, the width of streets is constrained by sidewalks and buildings. In this context, adding on-street loading areas in series is a valid method to increase bus stop capacity. A tandem bus stop is a linear bus stop with two loading areas on a dedicated bus lane where buses serve depending on the sequence in which they arrive at the stop since overtaking is not allowed. The objective of this paper is to provide an analytical methodology to help city planners to choose between conventional and tandem bus stops. This study focuses on the capacity gain of a tandem bus stop in the case where there are buses waiting in line. Current studies are based on simulation results only for particular cases. The model is applied to Barcelona, Spain, where the dwell time is described by a log-normal distribution according to the available empirical data. The results obtained in this paper indicate that a capacity gain of 30 to 70% can be achieved, which allows for substantial commercial speed increasing. If buses spend more time at the service position and the variability is low, the gain is greater. Our results suggest including in the Transit Capacity and Quality of Service Manual a more detailed description of the behavior of urban tandem bus stops, where the “effective number of berths” concept should be considered a variable (instead of constant) that depends on the dwell time characteristics.

    La presente investigación presenta la colaboración entre el CENIT y Renfe, que ha consistido en la elaboración de una metodología específica para la evaluación económica y social de la Alta Velocidad (AV) ferroviaria, con un enfoque innovador y de sistema, que permite evaluar la realidad de la AV ferroviaria en España de una forma rigurosa y a la vez imaginativa que supera los habituales CBA desarrollados para aspectos operativos (la AV incluye aspectos tácticos y estratégicos también).

    La congestión del tráfico en entornos urbanos y metropolitanos perturba la eficiencia de la logística de la ciudad contemplada como “fábrica de movilidad”, afectando a todos los colectivos sociales de forma directa e indirecta, empeorando la calidad de vida y penalizando las actividades comerciales y el acceso y entrega de productos en “la última milla”. Esta investigación define indicadores objetivos simples y sus homólogos subjetivos (a partir de la percepción de los usuarios) de forma genérica, lo que permite comparar distintos escenarios temporales y territoriales, y extender el análisis a distintas ciudades. Los indicadores definidos incorporan la distribución espacial de la congestión (para una franja horaria definida) y la distribución temporal a lo largo del día (para una zona concreta) dentro de un indicador global de congestión.
