The RAILGAP project started on 1st January 2021. It is structured into nine Work Packages (WPs) with different functions in order to fulfil its overall objectives. There are six technical WPs that will carry out the necessary tasks to deliver the technical objectives of the project, and there are also two WPs designated for ensuring an efficient management and coordination of the project as well as a dissemination and exploitation activities.

WP Goal
WP1 – Project Management and Coordination WP1 consists of all project coordination activities, including project planning, performance and financial control, quality assurance, risk management, emergency planning and the administration of EU funding.
The main objectives of this work package consist of:
  • The effective coordination of the project:
  • The efficient management of the common consortium activities; The effective overall administrative and financial management of the project;
  • The effective quality management;
  • The technical coordination of the technical work of the various WPs to keep the alignment with the overall objectives of the project.
WP2 – User requirements and constraints form railways directives, regulations, standards The main objectives of WP2 are:
  • Identification of the User Needs;
  • Transformation of identified User Needs into Functional and Not-Functional;
  • Identification of the constraints and the obligations set by both (a) the EU Regulations and Directives and (b) the Railway Standards on the use on new technologies (e.g. use of cameras mounted on-board of trains due to the privacy requirements and the European GDPR);
  • Definition of high level logical functional architecture of the RailGap infrastructure.
WP3 – Description of the measurements, specification of the measurement procedures, execution of field measurement campaigns and data storage/handling The main objectives of WP3 are:
  • State of the Art related to COTs hardware to meet user needs and/or user requirements;
  • Specification of the information to be measured and identification of the measurement equipment;
  • Specification and development of the measurement procedures;
  • Identification of the Engines to be equipped (e.g. two in Italy and one in Spain) with the on-board measurement environment and of the railway lines to be used for the execution of the Field Test Campaigns;
  • Electrical and mechanical designs of both of the on-board and trackside measurement environments, and their verification (intrusiveness analysis in accordance with EU Regulation No 402/2013);
  • Execution of Different Batches of Field Test Measurement Campaigns and management of the collected measurement data.
WP4 – Characterization of EGNSS, IMU, LIDAR, Camara Technologies in Railways The main purpose of this work package is to rigorously derive and validate the necessary error models and performance of sensor fusion solutions for railway precise and robust position and trajectory determination. This is done by statistical assessment of the error processes of different technologies such as Global Navigation Satellite System (GNSS), inertial measurement units (IMU), LIDAR and cameras in the railway environment and by deriving innovative fault detection and exclusion mechanisms and hybridization algorithms able to provide trustable confidence intervals.
WP5 – Assembly of the Measurement environment and development of the trackside central collector-definition of the concept phase of the on-board diagnostic recording unit The main objectives of WP5 are:
  • Definition and description of the architectural design of the Measurement Environment (for both on-board and trackside);
  • Specification of the functional and not-functional requirements of the Measurement Environment;
  • Development of the Measurement Infrastructure.

WP6 – Ground Truth definition, development and verification The main objective of this work package is to define the Ground Truth concept and methodology for its computation, the specification and development of a toolset for GTG Ground Truth Generation and their validation of previous toolset.
WP7 – Trackside Digital Map definition, development and verification The main objectives of this work package are to identify and design a toolset that will be used to develop the trackside Digital Map by using multisensory data collected directly from trains in commercial operation and to develop a methodology for the object detection and acquisition of key points that will be used as reference to compute their relative positions w.r.t. the train position during each train ride.
WP8 – Dissemination and Exploitation The main objective of this work package is to ensure that the project results and outputs are widely disseminated and effectively exploited by their target groups (including S2R).
WP9 – Ethics requirements The objective is to ensure compliance with the 'ethics requirements' set out in this work package.
