Among different types, the one considered in this paper is the so-called one-way car-sharing system whereby a user can begin and end a trip at any station of the system. At the same time, the Vehicle-to-Grid (V2G) concept is emerging as a possible innovative solution for smart power grid control. A management system that combines car-sharing system operations and V2G technology is a recent challenge for academia and industry. In this work, a mixed integer linear programming formulation is proposed to find the optimal management of electric vehicles in a one-way car-sharing system integrated with V2G technology. The proposed mathematical model allows finding the optimal start-of-day electric vehicles distribution that maximizes the total revenue obtained from system users and V2G profits through daily electric vehicles charging/discharging schedules. These schedules are based on mean daily users' electric vehicles requests and electricity prices. The model can be applied to evaluate the possible average daily profitability of V2G operations. In order to test the model performance, we applied it to a small-size test network and a real-size test network (the Delft network in the Netherlands). Under the model assumptions, the adoption of V2G technology allows to fully cover the daily charging costs due to users' trips and to obtain V2G profits by taking advantage of electric vehicles unused time without significantly reducing the satisfied car-sharing system demand. Most of the energy purchased to charge the electric vehicles batteries is provided back to the grid during energy peak load demand, creating benefits also for energy providers.

From the transportation insight, the railway electrification is expected to attract higher passengers’ demand, since the increase of commercial speed will influence the reduction of the total travel time, and, consequently, create the competitivity with other transportation modes. Therefore, in this work, we focus on investigating the opportunities for railway electrification by developing a novel Electrification Railway Network Design Problem (E-RNDP), which aims at determining the best set of railway lines to be electrified on existing railway network considering budget limitation. The objective of the proposed model is to minimize overall cost considering electrification, signaling, and CO2 socio-environmental costs. The proposed model has been tested on a real case study in Salento, Italy, where the obtained results highlight the benefits that we can achieve through railway electrification in terms of total CO2 socio-environmental savings. Additionally, for every electrified line, we obtain the optimal number of traction substations considering maximum distance coverage. The obtained solution resulted in CO2 emission savings of around 4716 CO2 tons per year and an environmental improvement of 37.37%. Furthermore, a sensitivity analysis is carried out according to different budget values, which could give insight into correlations between total infrastructure and emission costs to interested parties. Additionally, the proposed model could be applied to any real-size problem solving, and it could be useful for decision-makers to decide where to invest in railway electrification.

Although free-floating bikes allow much greater spontaneity and flexibility for the user, they need additional operational challenges especially in facing the bike relocation process. Then, we suggest a methodology able to generate spatio-temporal clusters of the usage patterns of the available bikes in every zone of the city, forecast the bicycles use trend (by means of Non-linear Autoregressive Neural Networks) for each cluster, and consequently enhance and simplify the relocation process in the network.

Le nuove forme di mobilità, infatti, possono esacerbare le disuguaglianze preesistenti nell'accesso ai sistemi di trasporto pubblico escludendo alcune aree urbane quali ad esempio i quartieri a basso reddito o quelli più lontani dal centro città, ovvero proprio laddove i residenti potrebbero beneficiare maggiormente di un nuovo servizio. L'obiettivo di questo lavoro è inquadrare questi aspetti e discuterli alla luce degli studi più recenti, profilando gli aspetti chiave da approfondire sia nella ricerca scientifica così come da parte dei professionisti della pianificazione.

The main initiatives are encouraging a shift from private to other transport modes by providing a fully integrated multimodal service in which the coordination and data sharing among different stakeholders are required. The idea of this paper is to analyze the mode choice, as well as the variables that affect the travelers’ airport access mode choice. For that purpose, we used multinomial logistics (MNL) regression to determine probability of mode choice given various multimodal chain alternatives. The inputs of the proposed model were based on the answers from the participants of the online survey which was disseminated in Europe. Through more than 2000 answers to the survey, we collected the data related to the factors that influence the airport access mode choice, travelers’ attitude, motives for traveling, as well as the socio-demographics of participants. Afterwards, we investigated the ...

In our model the terminal is assumed as a system that has to be designed and/or controlled in order to achieve the best performance on the basis of the existing resources. The terminal itself is assumed to be a node of the existing freight intermodal network that could improve his reliability from improving the performance of the activities at the nodes. From the theoretical stand-point the model has been based on Petri Net.
