This paper proposes models and methods to optimise train speed profiles in suburban areas order minimise total energy consumption. In achieve this target, an optimisation framework is developed for designing driving strategies, which requires a railway simulation model as subroutine. we focus on the define energy- efficient relative consumption, assuming motion parameters control variables. We consider two cases: with without recovery systems. Proposed are tested real case. Initial results...

Energy efficiency and train length may be critical during rescheduling, in particular if long freight trains are considered. The first aim of this paper is to investigate how current scheduling rescheduling models consider energy efficiency. second extend a model that considers for drafting minimizes not only delays but also consumption. A small numerical example shows procedure can fast yield significant reduction Thus, it worth further research. However, validation on larger instances,...

In this paper, we propose a model framework for providing optimal driving strategies and related speed profiles which minimise the energy consumption of rail convoys.Previous models were extended applied to evaluate effects different signalling systems upon operating costs.The proposed method was tested on real network, Cumana suburban railway (Italy).
Abstract Future railway systems will need the support of more precise and reliable information on train motion during operation, to fully exploit potential new technologies. Train are here intended as time series state characteristics, that is, position, speed, acceleration. This paper investigates use two different filtering formulations for better online estimations along track. Specifically, extended Kalman filters (EKFs) particle (PFs) used fuse kinematic measurements collected by means...
The continuing growth of urban regions coupled with their strong interactions transportation systems places great emphasis on the coevolution these systems. In this paper we introduce three developments. First, as a preliminary, dynamic model evolution retail structure is extended to show how hierarchies emerge. Secondly, ideas are applied in transport networks. Thirdly, it shown that such can be translated into planning context and notion an explicitly hierarchical introduced. An example...
Traffic noise is a significant externality in urban areas that reduces the quality of life and may produce non-negligible effects on human health.The main factor responsible for traffic individual transportation (cars motorcycles) more congested network, higher average level noise.An Urban Plan (UTP) tool managing mobility; Italy UTP provided under national laws one its objectives abatement.The manages network (road directions, signal settings, etc.) without providing new infrastructures.In...
This paper focuses on the optimization of freight trains operation for energy saving purposes, highlighting future challenges and current possibilities. A simulation-based approach generation speed profiles, implemented in Matlab, is here adopted with real data from onboard monitoring system. Results have highlighted two interesting aspects: give useful information during calibration simulation model, by referring to it possible a clear reference potential saving.
This paper presents an enhanced version of the Resource Conflict Graph (RCG) approach for railway rescheduling that considers reduction tractive energy consumption in process. The objectives and constraints considered freight train are different from those related to passenger trains. For example, there is generally more flexibility scheduling regarding routes departure/arrival times. On other hand, trains have frequent unplanned stops overtaking acceleration phases use significant energy,...
The hierarchical connection of Rail Traffic Management System (TMS) and Automatic Train Operation (ATO) for mainline railways has been proposed a while; however, few have investigated this with the real field. This paper studies in detail benefits limitations an integrated framework TMS ATO stochastic dynamic conditions terms punctuality, energy efficiency, conflict-resolving. A simulation is built by interfacing rescheduling tool stand-alone realistic traffic environment OpenTrack....

This paper proposes a Hybrid Dynamic-Kinematic Extended Kalman Filter (EKF) for the online estimation of train position, velocity and acceleration along track. In proposed EKF commonly used kinematic measurements are fused with dynamic information, i.e. active power used, to obtain more accurate estimates. also results in an onboard-only based model that will enable implementation next generation traffic management systems. Two case studies, on real data runs Swiss line, presented...
