The Implementation and Use of Conceptual Standards - The Case of the RDS-TMC Service

The topic of the paper concerns the implementation and use of standards. The standards which are in focus in the paper include conceptual models and descriptions of the functionality and information exchange which should be provided in order to deliver ICT-services. This implies that these conceptual standards are specifications and guidelines for the information systems used to provide ICT-services, and the intended users of these standards are the service providers. In order to investigate the implementation and use of these standards a case study has been performed at the Swedish National Road Administration (the SNRA) with a focus on the RDS-TMC service. The SNRA is the service provider for the RDS-TMC service in Sweden, and the RDS-TMC service is a mobile traffic information service based on radio communication, i.e. the RDS-channel. The implementation of the RDS-TMC service is based on two conceptual standards, the ALERT-C and Location Code standards. One goal with the case study has been to investigate how these standards have been implemented in the systems used to provide the service. Another goal has been to investigate how the standards affect the development, maintenance and usability of these systems, and the information exchange in the service delivering process

Geomatics for Mobility Management. A comprehensive database model for Mobility Management

In urban and metropolitan context, Traffic Operations Centres (TOCs) use technologies as Geographic Information Systems (GIS) and Intelligent Transport Systems (ITS) to tackling urban mobility issue. Usually in TOCs, various isolated systems are maintained in parallel (stored in different databases), and data comes from different sources: a challenge in transport management is to transfer disparate data into a unified data management system that preserves access to legacy data, allowing multi-thematic analysis. This need of integration between systems is important for a wise policy decisions. This study aims to design a comprehensive and general spatial data model that could allow the integration and visualization of traffic components and measures. The activity is focused on the case study of 5T Agency in Turin, a TOC that manages traffic regulation, public transit fleets and information to users, in the metropolitan area of Turin and Piedmont Region. In particular, the agency has set up during years a wide system of ITS technologies that acquires continuously measures and traffic information, which are used to deploy information services to citizens and public administrations. However, the spatial nature of these data is not fully considered in the daily operational activity, with the result of difficulties in information integration. Indeed the agency lacks of a complete GIS that includes all the management information in an organized spatial and “horizontal” vision. The main research question concerns the integration of different kind of data in a unique GIS spatial data model. Spatial data interoperability is critical and particularly challenging because geographic data definition in legacy database can vary widely: different data format and standards, data inconsistencies, different spatial and temporal granularities, different methods and enforcing rules that relates measures, events and physical infrastructures. The idea is not to replace the existing implemented and efficient system, but to built-up on these systems a GIS that overpass the different software and DBMS platforms and that can demonstrate how a spatial and horizontal vision in tackling urban mobility issues may be useful for policy and strategies decisions. The modelling activity take reference from a transport standards review and results in database general schema, which can be reused by other TOCs in their activities, helping the integration and coordination between different TOCs. The final output of the research is an ArcGIS geodatabase, tailored on 5T data requirements, which enable the customised representation of private traffic elements and measures. Specific custom scripts have been developed to allow the extraction and the temporal aggregation of traffic measures and events. The solution proposed allows the reuse of data and measures for custom purposes, without the need to deeply know the entire ITS environment system. In addition, The proposed ArcGIS geodatabase solution is optimised for limited power-computing environment. A case study has been deepened in order to evaluate the suitability of the database: a confrontation between damages, detected by Emergency Mapping Services (EMS), and Traffic Message Channel traffic events, has been conducted, evaluating the utility of 5T historical information of traffic events of the Piedmont floods of November 2016 for EMS services

Intensive Innovation Context and Design System Dynamics. The Case of Car Information Communication Entertainment (ICE) Systems

Recent literature on innovation strategy and organizational change has challenged the classical punctuated equilibrium pattern that alternates long periods of stability with short bursts of radical change in the dominant design of products. Research into high-tech sectors such as the computer industry and into the mass-production sector has addressed the issue of repeated radical innovation trajectories and proposed theoretical patterns for «neo-industrial organizations» , «intensive innovation-based strategies,» and «design-oriented organizations» ). This chapter analyzes such ever-changing contexts. We try to demonstrate that such innovation trajectories cannot be analyzed as merely a succession of product projects, but rather must be tightly connected to deep transformations in the «permanent» organization where they are found

SOA-Based Model for Value-Added ITS Services Delivery

Integration is currently a key factor in intelligent transportation systems (ITS), especially because of the ever increasing service demands originating from the ITS industry and ITS users. The current ITS landscape is made up of multiple technologies that are tightly coupled, and its interoperability is extremely low, which limits ITS services generation. Given this fact, novel information technologies (IT) based on the service-oriented architecture (SOA) paradigm have begun to introduce new ways to address this problem. The SOA paradigm allows the construction of loosely coupled distributed systems that can help to integrate the heterogeneous systems that are part of ITS. In this paper, we focus on developing an SOA-based model for integrating information technologies (IT) into ITS to achieve ITS service delivery. To develop our model, the ITS technologies and services involved were identified, catalogued, and decoupled. In doing so, we applied our SOA-based model to integrate all of the ITS technologies and services, ranging from the lowest-level technical components, such as roadside unit as a service (RS S), to the most abstract ITS services that will be offered to ITS users (value-added services). To validate our model, a functionality case study that included all of the components of our model was designed

INSPIRE-MMTIS: overlap in standards related to the Delegated Regulation (EU) 2017/1926

The COMMISSION DELEGATED REGULATION (EU) 2017/1926 of 31 May 2017 supplementing Directive 2010/40/EU of the European Parliament and of the Council with regard to the provision of EU-wide multimodal travel information services provides a list of static and dynamic data categories to be made available by Member States through the National Access Points. A range of data standards are required for the publication of such data categories, of which a subset (20 data categories) refers to static spatial data which are also linked to the INSPIRE Directive (Directive 2007/2/EC). Within this policy context, this document is the final report of the INSPIRE-MMTIS study, aimed to identify and analyse the overlaps and gaps existing among the relevant standards to be used for the sharing and reuse of data under the remit of the above mentioned Delegated Regulation. Recommendations for both data providers and data users on how to deal with the overlaps/gaps have been formulated, based on a series of use cases. The analysis performed in the study represents a first step to support Member States in the implementation of the MMTIS Regulation. Results demonstrate that the analysed standards are sufficient to start implementing the Regulation, although several recommendations show that further work is necessary (given e.g. gaps in standardisation and the need for European profiles and conversion tools).JRC.B.6-Digital Econom
