Integrated mobility management (I2M), Energy and Noise & Vibration - S2R-CFM-CCA-01-2019

Deadline: Jun 18, 2019  
CALL EXPIRED

SPECIFIC CHALLENGE

Integrated Mobility Management (I2M)

The project IN2RAIL (GA number 635900) has delivered a first system design for an integrated Communication Infrastructure to link the defined rail operation services and their field assets. This platform (Integration Layer) uses standardized data structures and processes to manage the data exchange between different stakeholders and provides a gateway for data exchange with external clients. The availability of such data will enable analyses to enhance rail traffic management, including improved planning and timetabling, reliable and resilient operations and informed asset investment and maintenance decision making.

The most critical factor to realize the proposed system concept is the maturity of the Conceptual Data Model with embedded elements of information required from the different applications of subscribed services/clients. To achieve this goal, applied operational procedures or technical functionalities must be described in such depth that the necessary data to be received or send from/to other clients can be specified. If preceding projects deliver their targeted outputs, the works proposed for WA4.2 in this project will not face significant risk to be completed.

Energy

The challenge regarding energy is linked to the need to reduce energy consumption within the railway sector in order to ensure that the environmental advantage of railways remains or increases. The necessity to reduce energy costs, an important part of the total Life-Cycle Cost, to contribute to the general S2R objective “Reduced operating costs” is also a priority. Furthermore, reduction energy consumption from HVAC is needed is required, as HVAC accounts for a major part of the energy consumption from the traction.

Noise and Vibration

In order to ease vehicle certification and reduce the associated cost and time expenses without penalising the real vehicles noise performance, virtual certification will play an important role in the near future. Thus, current exterior noise simulation tools require further research and validation in order to ensure that the procedures and methodologies applied, and the results obtained represent the noise performance the real train will have. Additionally, current noise measurement procedures lack the possibility to accurately separate noise sources on pass-by noise tests, and do not cover the common vehicle scenarios (including different track types). Separation of contributions is relevant both for vehicle validation and for source ranking prior to mitigation measure implementation, and the improvement of separation techniques shall finally lead to more flexibility, better comparability and hence a better vehicle characterization in current homologation procedures and for the customers.

SCOPE

Having regard to the Union policies and targets on decarbonisation, taking into consideration that automation and digitalization are key enablers of a drastic railway system transformation, in order to address the challenges described above, the proposals should address all the following work streams, in line with the S2R MAAP.

Work stream 1: I2M

The action to be funded under topic S2R-CFM-IP-01-2019 is expected to develop prototypes up to TRL6 for the TMS integration layer.

IN2SMART (grant agreement number 730569) further progressed Railway Information Measuring and Monitoring System (RIMMS), Dynamic Railway Information Management System (DRIMS) and Intelligent Asset Management Strategies (IAMS) demonstrators, complementing the work previously done in past project (IN2RAIL).

The action to be funded under the topic S2R-OC-IP2-02-2019 (linked to TD2.9) will provide a demonstration platform for an Integration Layer-enhanced TMS.

The action to be funded under this topic will therefore specify and develop necessary Interfaces to allow Freight and Passenger Operations, Maintenance Services and Traffic Management Systems to access the different databases via the integrated ICT and design a concept and to test and validate the proposed prototypes on the platform to be delivered by the action to be funded under the topic S2R- OC-IP2-02-2019.

- Integration of Business Services
Technical Engineering: This activity shall encompass all coordination and system engineering activities required to ensure compatibility, interoperability and design of the Interfaces of the Integration Layer to TMS, Asset Management Systems, Passenger and Freight Planning and Operation Services. Development Specification and Prototypes for APIs including specific Plug-ins: The objective of this activity is to specify and develop prototypes up to TRL 3 for the APIs between the Integration Layer, TMS, Asset Management Systems and Passenger and Freight Planning and Operation services. These activities are based on the requirement specification developed under the WP6 of X2RAIL2 (GA number 777465) and WP7 of IMPACT-2 (GA number 777 513).
Develop a concept and design Guidelines for a Demonstrator: Developing a concept and the design guidelines for a demonstrator to test and validate the prototypes. This task is closely linked with the coordination and the works proposed for the action to be funded under the topic S2R-OC-IP2-02-2019 (establish a test bench to test and validate all prototypes related to the Integration Layer).

- Advanced Business Service Applications
Specification and Development of prototypes for TMS applications: The Objective of this work is to specify and develop prototypes for applications in a TMS addressing traffic prediction, real-time control of the operation, maintenance planning and operational decision support features. This will enable:

1. Optimised service intent, timetable and schedule planning across different time- resolutions for efficient TM operations;

2. The ability to predict and prevent (e.g. pre-planned alterations for predictive maintenance interventions); or quickly detect unplanned operational disruptions and minimise their impact and incident recovery (e.g. reactive maintenance, conflict resolution);

3. The ability to re-optimise timetable planning, as more rail and mobility system operation data is made available, thereby facilitating continuous improvement in TM and;

4. Additional data to be provided to other non-rail mobility providers, to enhance overall mobility offering.

Examples of additional data which can be used to improve Traffic Management (TM) operations can include but are not limited to:

• -  Rolling stock and crew availabilities (planned vs. actual), small events which may affect effectiveness of macro-level timetabling;

• -  Live passenger movements and overcrowding, availability and incentivising multi-modal options to alleviate demand on rail during abnormal operational conditions;

• -  Smart maintenance operations based on predicted behaviour of infrastructure assets (outputs from IN2SMART).

This could lead to the creation of advanced prototypes, including but not limited to:

1. Rolling stock and crew availability management systems to reduce likelihood of disruption to planned TM operations;

2. Enhanced freight tracking including better coordination with ‘last-mile’ logistics providers;

3. Automated decision support tools for TMS to cater for preventative maintenance requests of a railway asset, based on Intelligent Asset Management Strategies developed under IN2SMART, minimising system disruption on macro-level timetable;

4. Demonstration of pre-emptive information output to minimise disruption to passenger journeys and maximise speed of rail operational recovery, based on discrete events, e.g. passenger overcrowding, rail network disruption, TMS failure.

5. Enhanced standard operator workstation HMI design to accommodate new information flow and decision support functionalities for above prototypes.

Work stream 2: Energy

The activity should provide support to all S2R Innovation Programmes (IPs) and Technology Demonstrators (TDs), most notably as regards the energy calculation methodology and agreed boundary conditions produced in the project FINE-1 (Grant agreement number 730 818).

The existing list of energy-related TDs shall be reviewed for matching with the updated MAAP. Once the energy related tasks have been confirmed, respectively identified for each IP, they should be analysed with respect to their potential contribution to energy saving.

The action shall undertake the following activity:

1. Update of the energy KPI, creating specific TD input consolidation groups by market segments and continue the data gathering from the TDs;

2. Supporting the IPs and TDs for estimating energy improvement;

3. Carry out pre-standardisation work: Energy-efficient technologies and strategies should be

   analysed from a whole life cycle perspective;

4. Review the energy baseline defined in FINE-1 and collect lessons learned in the application as a reference for the evaluation of energy savings of new S2R technologies;

5. Review and update the “future railway system with respect to energy” deliverable work of FINE-1 as ;

7. Theoretical Evaluation of energy savings achieved (via simulations and calculations with the

   support of the tool developed in the project OPEUS29;

8. Regarding HVAC, the activity should define the state-of-the-art of the technology, define additional sub-level KPIs as well as energy savings evaluation methods; deliver an analysis of potential energy (HVAC related) savings shall be carried out along a train journey in order to investigate e.g. wasted heat and braking energy utilisation. The thermal car body model used for this purpose shall apply energy baseline scenarios as calculated by the OPEUS tool.

Work stream 3: Noise

1. Exterior noise simulation tools

The objective is to support the development in the complementary action to improve simulation capabilities for exterior noise at standstill and pass-by, based on existing tools stemming from ongoing and past projects. The modelling of exterior noise includes adding together noise sources placed on different parts of the train to simulate the resulting noise levels. The exterior noise modelling tools and methodologies to be enhanced and validated are those currently in use by industry members with respect to standstill and pass-by noise. The focus will be set on modelling of noise sources sound power and directivity and of integration effects.

The activity should consequently focus on the following two areas:

1. Defining requirements for the modelling to be carried out by the action to be funded under the topic S2R-OC-CCA-01-2019.

Foreseen achievable Technology Readiness Level: TRL3/4

Considering the “18C044-0C WHITE PAPER REFERENCE CCS ARCHITECTURE (RCA) BASED ON ERTMS” developed by the ERTMS Users Group and the EULYNX consortium and provided to S2R in July 2018, and following the ongoing collaboration initiated with the promoters of such initiative for the integration of the RCA in the S2R Programme, a final high level decomposition of RCA is expected be delivered to S2R by April 2019. The S2R Members should firstly verify the impact that the RCA would have or potentially have on the content of each work streams activities and subsequently each CFM proposal should be aligned, as far as possible, against the latest progress on the Reference CCS Architecture, in particular the system approach and interoperability of solutions must be ensured across S2R IP/CCA activities and for future developments.

EXPECTED IMPACTS

I2M

•   Additional services through integrated communication processes and permanent availability of status data in one common layer will significantly improve the performance of TMS. This is key to achieve the targets for capacity growth, reliability improvement and cost reduction.

•   Capacity Increase and Cost Reduction
  Improved business logic in the TMS integrating dynamically updated asset status data received via the proposed interfaces asset will enable the creation of a much more flexible and consistent time tables for cargo services which will reduce the “disturbances” caused by freight traffic on lines which are used also by passenger trains.
  This will lead to a higher utilization of the theoretical line capacity hence decrease the operational cost for IMs. Also a more robust (flexible) time table for Freight trains will reduce unnecessary waiting times for slots and reduce the OPEX for Freight Services.

•   Customer experience
  Overall customer experience is affected by not only the rail assets controlled by TMS, but also the interconnecting service providers at either end of their journey, including modes of transport to and from stations and pedestrian experience within stations. Therefore the proposed scope should enable service providers at each stage to deliver services to improve seamless customer experience.
  Where disruptions to regular service occur, such sharing of data can enable enhanced ‘service- recovery’ actions to take place, to minimise any negative effects to the customer experience.

•   Increase of Reliability of Train Services through increase of the Availability of Assets Maintenance operations will benefit from a dynamic update of the traffic status via the Integration Layer and its Interfaces. This will allow those services to plan much better their services operations. A quantification of improvement of this KPI must be originated from IP3 TD6 and TD8 (Maintenance Strategies) reflecting the better usage of available slots for maintenance.
  Improved effectiveness of maintenance operations will increase the reliability of all train services, hence increase further the capacity utilization and decrease operational cost.

  Energy

•   The expected impact of the research and innovation action in the field of energy will be linked to determining the potential energy improvement of technical innovations in order to decide which innovations should be applied when new trains or infrastructure assets are purchased.

•   In addition, the reduced energy consumption, thanks to the use of new technologies, should contribute to the reduction of the environmental impact of the railway sector and help to increase the competitiveness of rail transport due to reduced energy cost.

•   The standardisation of the simulation methodology and parameters as well as measurement procedures for the estimation and verification of energy consumption supports the general S2R objective of “simplified business processes”.

•   Actions will contribute to contribute to energy-related standardisation and reinforcement of energy-efficient technologies development both through technical developments inside Shift2Rail and also market demand for Life Cycle Cost-optimized solutions.
