The adoption of the HD-ERTMS for improving the capacity of single-track railway lines

by Michele Napolitano, Luca D'Acierno, Luca De Matteis, Mario D'Avino, and Marilisa Botte

Proceedings of the 23rd IEEE International Conference on Environment and Electrical Engineering (IEEE EEEIC 2023) and 7th Industrial and Commercial Power Systems Europe (I&CPS 2023), Madrid, Spain, June 2023, 2023

Moreover, the signalling systems used in rail transport have evolved to become increasingly efficient. In particular, systems based on the ERTMS/ETCS (European Rail Traffic Management System/European Train Control System) are being developed recently because they guarantee interoperability at the European level, as well as considerably improve the performance of the rail systems. In this context, this paper analyses the use of the HD-ERTMS (i.e., High-Density ERTMS), normally applied in the case of railway nodes (as, for instance, complex stations) of double-track lines, in the case of single-track railway lines. Preliminary results have shown that the HD-ERTMS allows forwarding consecutive platoons of rail convoys in the same direction thus increasing the line capacity by up to 60%.

Keywords: signalling system, HD-ERTMS, railway system, single-track line, user waiting time, station platform.

The adoption of micro-mobility solutions for increasing student accessibility: The case study of the University of Naples, Italy

by Luca D'Acierno and Marilisa Botte

Proceedings of the 22nd IEEE International Conference on Environment and Electrical Engineering (IEEE EEEIC 2022) and 6th Industrial and Commercial Power Systems Europe (I&CPS 2022), Prague, Czech Republic, June-July 2022, 2022

The former is affected by settled activities; the latter depends on features of the supply system. From a sustainable perspective, one of the key strategies is promoting the use of active modes and micro-mobility options. In this context, the paper aims to investigate the variations in student accessibility (i.e., passive accessibility) due to the adoption of a micro-mobility solution. To show the feasibility of the proposed approach, it has been applied in the case of university plexuses in the Fuorigrotta district (Naples, Italy). Simulation results confirm that such solutions increase the accessibility level and show that they are preferred by users as first/last mile options, as well as for replacing pedestrian trips. Moreover, the provided outcome reveals the effectiveness of the proposed methodology as a Decision Support System (DSS) for helping micro-mobility operators to design service features.

Keywords: accessibility, public transport, micro-mobility solutions, student mobility

Assessment of rail service capacity under the current regulations aimed at ensuring social distancing conditions against the COVID-19 pandemic

Many regulations and rules have been and still are enacted by the world’s governments to minimise the level of risk to which the population is exposed. The majority of them aims at ensuring people social distancing and, in this context, the public transport sector plays a crucial role. Indeed, guaranteeing social distancing on buses or trains, while maintaining good service quality at the same time, represents a very challenging goal. Within this framework, the paper presents a methodology for optimising rail service operations thus satisfying mobility demand while complying with the maximum occupation coefficients allowed by current regulations. In order to show the goodness of the proposed method, it has been applied in the case of a real regional rail line in the south of Italy.

Keywords: Covid-19 pandemic, Social distancing, Rail service capacity, Occupation coefficients

Modelling of interactions between rail service and travel demand: a passenger-oriented analysis

The proposed research is situated in the field of design, management and optimisation in railway ... more The proposed research is situated in the field of design, management and optimisation in railway network operations. Rail transport has in its favour several specific features which make it a key factor in public transport management, above all in high-density contexts. Indeed, such a system is environmentally friendly (reduced pollutant emissions), high-performing (high travel speeds and low values of headways), competitive (low unitary costs per seat-km or carried passenger-km) and presents a high degree of adaptability to intermodality. However, it manifests high vulnerability in the case of breakdowns. This occurs because a faulty convoy cannot be easily overtaken and, sometimes, cannot be easily removed from the line, especially in the case of isolated systems (i.e. systems which are not integrated into an effective network) or when a breakdown occurs on open tracks. Thus, re-establishing ordinary operational conditions may require excessive amounts of time and, as a consequenc...
