“…One of the major obstacles to these improvements, especially in the case of ports that are located within cities and near the historic centre, is essentially the lack of space. Furthermore, the increase in port traffic also affects the increase in road traffic, affecting the network reliability and with consequent environmental, social and economic externalities [ 50 , 51 ].…”

The purpose of this work is to propose a methodological framework to evaluate the reuse of areas located close to the port as “retro-port”, in order to reduce the externalities caused by Ro-Ro freight terminal operation and the burden of freight deliveries in urban areas. In this regard, an analysis of the main variables involved in this process is presented, with reference to terminal traffic, terminal capacity, accessibility to the port and freight handling infrastructures. The results of this research constitute the base to support and improve urban logistics activities, rethinking the use of elements and areas that characterize the port and its surroundings. These findings pave the way for further research related to the design and dimensioning of retro-port and the realistic implementation of an urban consolidation centre.

“…The emissions are estimated using an average speed-based emission methodology presented in [25]. Due to the macroscopic nature of the network, this was the methodology selected to estimate emissions, since it only requires each road segment's average speed, which is one of the VISUM traffic model's main outputs.…”

COVID-19 pandemic impacted the behaviour of travellers. While worldwide, overall emissions decreased during the lockdown, shared mobility options may be perceived as less safe in a post-pandemic reality, leading to increased emissions due to expanded individual transportation. In particular, intercity trips entail numerous environmental impacts, such as emissions. The main objective of this paper is to assess how intercity corridors’ emissions vary when travel behaviour of the population changes following a pandemic. Based on a macroscopic modelling framework, the methodology consisted of three main phases: data collection, traffic modelling and emission modelling. Different scenarios related to the impact of the pandemic were developed, and their impacts were analysed using several key performance indicators related to CO2 NOx emissions and travel time. Findings suggest that reducing the average number of occupants per vehicle reduces emissions, which do not increase linearly with the number of vehicles. Compared with the baseline scenario (occupancy rate of 1.30), the most extreme scenario (occupancy rate of 1.00) may result in an increase in both CO2 and NOx emissions by approximately 30%. These results highlight the importance of making public transport and carpooling not only safe but also safe as perceived by users.

“…However, reducing costs must also be understood in the sense of reducing environmental pollution. The continuous use and the consequent reduction in the number of vehicles in circulation leads to a drastic reduction in CO 2 emissions into the atmosphere [ 18 – 20 ].…”

The spread and development of shared mobility makes it possible to offer users various forms of shared service that promote a sustainable approach. The choice of transport mode often depends on the distance travelled and the motivation for the journey. Among the conditions and variables that most influence the propensity to use a shared transport mode, the distance between the users’ places of origin or destination and the parking areas covered plays an important role, especially in the case of station-based type. The common system that has become more and more widespread in Italy is car sharing, with its various forms (i.e. station-based, free-floating, electric vehicles) that allow the use of reserved parking spaces or shared with other circulating vehicles. In urban areas, people generally tend to walk the first and last mile or use micro-mobility, while for longer distances they tend to use private or shared motor vehicles. Starting from this premise, this thesis provides a methodology for evaluating the effectiveness of car sharing by measuring the probability of using it based on parking distance. The proposed model is based on the estimation of O/D matrices with associated distance levels and the calculation of a probability index derived from several distance combinations. This research lays the foundation for a deeper analysis, which includes model calibration for different common mobility solutions and the evaluation of user probability in relation to implemented common mobility systems in several case studies.
