Global MEC supporting automotive services: from multi-operator live trials to standardization

Authors: F. Arneodo (5T), Andrea Laganà (TIM), R. Lesca (5T), D. Sabella (Intel), altri
Publication: IEEE Conference on Standards for Communications and Networking (CSCN)

The automotive domain is a critical area for the introduction of MEC (Multi-access Edge Computing) infrastructure in 5G systems, since it can benefit from moving cloud computing capabilities and IT service environments to the edge of the network. However, it brings several challenges, especially the need for easy data exchange in multi-operator environments. This paper describes the first known development of edge federation/roaming for a vehicular use case. This has been carried out through a MEC live trial by several international players, including network operators, neutral hosts, car manufacturers, infrastructure vendors and technology providers. It also describes the role of standards, in particular 3GPP, ETSI MEC and GSMA’s OPG (Operator Platform Group) for enabling inter-working between operators and car makers to provide global MEC support for automotive services. Trials and standards can energize the deployment of 5G and so advance the benefits of MEC for end users.

Autori: Arnone M., Dmastro T., Negrino C, Arneodo F., Botta D., Friuli G.
Proceedings of 14th ITS European Congress, Lisbon, Portugal, (Postponed).


Since 2009 Piedmont Region has started the design of a Public Transport (PT) integrated electronic ticketing system (BIP – Biglietto Integrato Piemonte) on the whole regional area. The project was aimed at increasing user accessibility through more flexible electronic ticketing. This paper focuses on a specific BIP application that, using data gathered in BIP environment, enables public stakeholders to have a detailed monitoring of PT service users’ behaviours, that represents a fundamental element for PT planning, programming and management. The user behaviour estimation, based on state of art literature, covers a whole regional area with heterogeneous transport modes and a complex transport network. Results were so promising that the algorithm has become a software component used in every regional BIP PT user behaviour analysis. The following chapters provide details on data, algorithms and tests and results developed to estimate travellers’ habits through the regional BIP platform.

Cooperative ITS Services Deployment in Turin

Autori:Arneodo F., Lesca R., Gagliardi G., Botta D., E. Bonetto, Brevi D.
Proceedings of 14th ITS European Congress, Lisbon, Portugal, (Postponed).


The Municipality of Turin has developed a strategic plan for the evolution of currently available ITS services towards the “Cooperative” model (C-ITS). A relevant task is the implementation of core technologies for Vehicle-to-Infrastructure communications (V2I). This paper describes two of the City’s main initiatives focusing on connected, cooperative and automated mobility, the “Torino Smart Road” and “C-ROADS Italy 2” projects. 5T is in charge of deploying those C-ITS services on the behalf of the Municipality, also in cooperation with Links Foundation research centre. In this paper, an overview is provided for both the mobility scenarios in Turin and the existing ITS services. The C-ITS deployment activities are summarized, as well. Finally, an account is given of the prototypal implementation of a roadwork warning C-ITS service and the major technical challenges, in particular concerning the matching between DATEXII and C-ITS messaging and the implementation of a “hybrid” 5G cellular/short-range communications infrastructure

TuST: from Raw Data to Vehicular Traffic Simulation in Turin

Autori: Rapelli M., Casetti C., Gagliardi G.
Pubblicazione: Proceedings of IEEE/ACM 23rd International Symposium on Distributed Simulation and Real Time Applications (DS-RT), 7-9 October 2019, Cosenza, Italy


Traffic simulations are becoming a standard way to study urban mobility patterns, to evaluate new traffic policies and to test modern vehicular technologies. For this reason, in recent years, mobility projects pushed towards an increase in the demand of traffic simulators and towards an extension of their area of investigation, aiming at covering a whole city and its suburbs.
In this paper we describe the methodology we followed in the creation of a large-scale traffic simulation of a 400-Km2 area around the Municipality of Turin. Our preliminary results demonstrate that a complete modeling of such a wide tool is possible at the expense of minor simplifications.

CORE project: policy, standards and harmonisation in satellite navigation based telematics for the transport of dangerous goods

Autori: Fazio D., Giaquinto D., Lia S., Arneodo F., Louette E., Mechin J.
Pubblicazione: Proceedings of 25th ITS World Congress, 17-21 September 2018, Copenhagen, Denmark

Dangerous goods transport regulations aims to protect everyone either directly involved (consignors or carriers), or who might indirectly become involved (emergency services, public). ADR /RID /ADN regulations assign duties and define rules, for minimising the hazards related to the carriage and the risk of incidents, and guarantee an effective response. Current regulations envisage paper form documents, for the purposes of transport operations, law enforcement and accidents (retrieved by police and emergency services).
Today, the majority of the companies transporting hazardous materials by road and rail have tracking and tracing solutions/services (satellite navigation based), which gather in electronic form most of the information required in the paper transport documents.
Over the last few decades, there has been a growing awareness of the authorities towards the benefits generated by the adoption of these solutions on a large scale, for:

  • Enhanced efficiency, safety and security (improved law enforcement and risk assessment, reduced accidents/relevant consequences, environmental damage and emergency response time)
  • Introduction of electronic (digitalised) transport documents .

Various initiatives have been developed in Europe to:

  • Increase the reliability of the tracking and tracing solutions/services through advanced technologies (e.g. based on the European GNSS and on multi-GNSS capabilities)
  • Validate the use of telematics to meet regulations and encourage the adoption of electronic transport documents.

However these initiatives are fragmented, geographically spread, lacking of a common/harmonised approach for a technical/functional architecture and standards, at national and international levels. Moreover, they require information sharing by the involved business actors and stakeholders, without robust incentive models.
In this context, the European CORE project (www.coreproject.eu) develops a best practice based on a flexible architecture and standards, and involving different countries. Its outcomes contribute to the harmonisation of cross-border operations, underlying policies and regulation.

Data standards for system interoperability and people mobility

Autori: Bourée K., Arneodo F., Duquesne C. , Nitsch G.
Pubblicazione: Proceedings of 7th Transport Research Arena TRA 2018, April 16-19, 2018, Vienna, Austria


“Mobility”, “interoperability”, and “inter-modality” are concepts expressing both objectives of services and characteristics of systems. How interoperable and intermodal systems influence personal mobility is intuitive and often discussed. In public transport, interoperability between fare systems, for instance, is an important step towards “seamless travel” by allowing users to access public transport in different areas with one single medium (“ticket”), while interoperability between trip planning systems allows for user-friendly passenger information and thus provides a necessary condition to ease the mobility of people. Truly interoperable systems follow a holistic approach in respect of transport, and provide the combination of different modes/means of transport within the same journey. CEN Technical Committee 278 WG3 developed a particularly useful standard for data structures (Transmodel) which acts as a reference for other standards, and hence facilitates the definition of the necessary requirements to make EU-wide multimodal travel information services accurate and available to all.

An operational framework to integrate traffic message channel (TMC) in emergency mapping services (EMS)

Autori: Arco E., Ajmar A., Arneodo F. e Boccardo P.
Pubblicazione: European Journal of Remote Sensing, Volume 50, 2017


Traffic Message Channel (TMC) is a technology for delivering traffic information to vehicle drivers. Sources of traffic information typically include police departments, Traffic Information Centers (TICs), camera systems, traffic speed detectors, floating car data, so on. Both public and commercial TMC services are operational in many countries. TMC messages can be also exchanged among TICs formally using standard protocols. The term emergency mapping (EM) encloses all activities finalized to produce geographic data on the consequences of a natural or man-made events. Emergency mapping services (EMS) normally exploit satellite or aerial imagery in order to extract the extent of the area affected and the impact on local infrastructures. In this paper, the authors verify the impact of the integration of TMC information in routinary EMS, exploiting the flood event occurred in November 2016 in north-west Italy as a case study. After an introduction to the problem and a description of TMC technology and of EMS, all technical aspects related to the integration of the two services are deeply described. Extracted traffic events have then been integrated and compared with EM products generated for the event previously mentioned. Finally, opportunities, limits, future enhancement and refining are summarized in the conclusions.

Managing by Data the Governance of Regional Transport Network

Autori: Arneodo F. Botta D., Gagliardi G.
Pubblicazione: Proceedings of the 11th ITS European Congress, 6-9 June 2016, Glasgow (Scotland)


In this paper, a new approach to mobility management is described as well as the Italian reference scenario, where the transportation offer is changing towards the provision of different transportation services like public transport, car sharing, bike sharing, public transport for weak mobility demand areas. The role of the Public administration becomes crucial either for the funding of public transport or the governance of the mobility services portfolio, with a change of mobility concept towards a mobility as a service one. Piedmont Region, a Local Public Administration, charged 5T Company to realize a Regional Service Centre (CSR) for the Governance of the regional mobility services. An appropriate application of ITS and Business Intelligence techniques on CSR data will enable a Managing by data approach to reach this goal.

DeCoClu: Density consensus clustering approach for public transport data

Autori: Fiori A., Mignone A., Rospo G.
Pubblicazione: Information Science, Volume 328, 20 January 2016, pp 378–388

Automatic Vehicle Monitoring (AVM) systems are exploited by public transport companies to manage and control their fleet of vehicles. However, these systems are usually based on the background knowledge of the transport network which can change during the time and in some cases can be missing or erroneous. GPS data and other information captured by the vehicles during their work can be exploited to update the network knowledge. This paper presents a novel approach, namely DeCoClu (Density Consensus Clustering), that aims at mining the topology of a public transport network by means of a consensus clustering density-based approach. In particular, the method exploits static information from time series of positioning signals (i.e., GPS data) to infer geographical locations of stops by means of a consensus clustering strategy based on a new distance function. Moreover, the logical pathway of a route (i.e., stops sequence) is defined by an Hamiltonian cycle. Experiments performed on real-data collections provided by a public transport company demonstrate the effectiveness of the proposed approach.

Transmodel – NeTEx – EPTIS: a European Standard for Modelling and Exchanging Fares

Autori: Arneodo F. , Boureé K., Tibaut A.
Pubblicazione: Proceedings of the 22nd ITS World Congress, 6-9 October 2015, Bordeaux (France)

Interoperability between fare systems is an important step towards “seamless travel” and is a necessary condition for the efficient provision of passenger information on fares across transport modes. Achieving this goal presents a technical challenge and to help reach it the European project NeTEx/EPTIS proposes a standardised data exchange format for fares that can be used across Europe. The project specifies how to model the complexity of European fare structures, using a data model based on generic concepts that can represent the core elements of any fare system, independently of any specific set of concrete fare products offered for sale, and then derives a standard interface as an XML schema implementation. The European Reference Data Model for Public Transport (Transmodel), extended to cover the requirements of heavy rail, is used as a basis for the proposed fare model. An early implementation of NeTEx is achieved by the project BIPEx.

Pubblicazione: Proceedings of the 22nd ITS World Congress, 6-9 October 2015, Bordeaux (France)

In this paper a new perspective in traffic control using vehicular traffic data sources and the relevant evaluation methodology are presented. This study was performed in the Piedmont Regional Traffic Supervisor (SVR) project context: the SVR was developed by 5T company with the main aim of traffic monitoring, forecast and control, over all the Piedmont Region road network. This is a radical evolution of the concept: the extension and the different typology of the controlled area require some specific technical choices that are described in the paper. Besides, the wideness of the controlled area requires also an integration of classic physical sensors with new vehicular sensors (Floating Car Data – FCD): details about real-time data acquisition and treatment, as well as about KPI identification and estimation will be provided.

Tell me the bus – A new approach in developing applications for Public Transport end users

Autori: Arneodo F. Gastaldi D., Botta D.
Pubblicazione: Proceedings of the 10th ITS European congress, 16-18 June 2014, Helsinki (Finland)


In a city like Turin (less than 1 million inhabitants) more than 57% of Public Transport (PT) users are systematic clients; in other words, they take the same bus line twice a day every single workday. These persons know their PT lines and their itinerary much better than Public Transport Companies (or our algorithms) will ever do. In this paper a change of paradigm is proposed: instead of supplying people with complex forecast and aggregated data, we investigate the way to allow them accessing real-time, low level data in a practical and user friendly way. This will enable skilled passengers to put in practice their very personal experience in understanding the status of their PT line and, in short, make their on “forecasts”.

During last years, we assisted to an increment of mobility demand, implying the need of adequate infrastructure and efficient public transport. The deployment of informative services and Intelligent Transport Systems (ITS) assumed a fundamental importance to address mobility demand, strictly correlated to the territory characteristics. At the same time, mature Geomatic technologies, especially related to GPS differential positioning (both in real time and in post processing), mobile mapping systems (MMS), remotely sensed imageries (aerial, satellite and UAV platforms), archiving and management systems (Spatial Data Infrastructure – SDI) will play a crucial role. These applications to infomobility and ITS are described in this paper.

Piedmont Integrated Ticketing An innovative and strategic (and smart) approach

Autori: Arneodo F., Botta D., Migliasso D.
Pubblicazione: Proceedings of the 9th ITS European congress, 4-7 June 2013, Dublin (Ireland)


This paper describes the design and implementation of the Piedmont Integrated Ticketing project (BIP – Biglietto Integrato Piemonte) and its interoperability with any public service already supporting or willing to support this technology. The interoperation among different service operators will be assured by means of a single Regional Service Centre (the “CSR-BIP”) sharing data about services and customer usage with transport operators and Public Administration, by means of a standardized transfer data protocol (called BIPEx) compliant with the most up-to-date international standards. The same informative content will be used for dedicated informative services. Moreover, all services compliant to the BIP system will be accessed by users through a pure contactless smart card, with its Card Data Model, defining its content and the rules to access it. Customers will be able to change between Public Transport operators or other transport systems (i.e. car and bike sharing) and even cultural services (EDISU or PYOU Card) or regional museums, without the need to acquire a dedicated “ticket” for each. One centre, one protocol and a single smart card will enable one of the most integrated ticketing and informative service system ever.

The increasing number of vehicles moving on the roads causes all over the world traffic problems, especially in the urban centres. The paper presents the main solutions to the urban traffic problem starting from the long experience of Turin in limited access areas and moving towards the recent experiences in pay-per-use schemes. Nevertheless the upcoming access control solutions do not take into account a set of critical factors, decisive for their sustainability. The “access rights” represent a more sustainable access control system and are able to ensure benefits in terms of both effectiveness and social acceptability of demand management solutions.

Proceedings of 14th ITS European Congress, Lisbon, Portugal, (Postponed).


The Municipality of Turin has developed a strategic plan for the evolution of currently available ITS services towards the “Cooperative” model (C-ITS). A relevant task is the implementation of core technologies for Vehicle-to-Infrastructure communications (V2I). This paper describes two of the City’s main initiatives focusing on connected, cooperative and automated mobility, the “Torino Smart Road” and “C-ROADS Italy 2” projects. 5T is in charge of deploying those C-ITS services on the behalf of the Municipality, also in cooperation with Links Foundation research centre. In this paper, an overview is provided for both the mobility scenarios in Turin and the existing ITS services. The C-ITS deployment activities are summarized, as well. Finally, an account is given of the prototypal implementation of a roadwork warning C-ITS service and the major technical challenges, in particular concerning the matching between DATEXII and C-ITS messaging and the implementation of a “hybrid” 5G cellular/short-range communications infrastructure

“Mobility”, “interoperability”, and “inter-modality” are concepts expressing both objectives of services and characteristics of systems. How interoperable and intermodal systems influence personal mobility is intuitive and often discussed. In public transport, interoperability between fare systems, for instance, is an important step towards “seamless travel” by allowing users to access public transport in different areas with one single medium (“ticket”), while interoperability between trip planning systems allows for user-friendly passenger information and thus provides a necessary condition to ease the mobility of people. Truly interoperable systems follow a holistic approach in respect of transport, and provide the combination of different modes/means of transport within the same journey. CEN Technical Committee 278 WG3 developed a particularly useful standard for data structures (Transmodel) which acts as a reference for other standards, and hence facilitates the definition of the necessary requirements to make EU-wide multimodal travel information services accurate and available to all.

DeCoClu: Density consensus clustering approach for public transport data

Autori: Fiori A., Mignone A., Rospo G.
Pubblicazione: Information Science, Volume 328, 20 January 2016, pp 378–388

Automatic Vehicle Monitoring (AVM) systems are exploited by public transport companies to manage and control their fleet of vehicles. However, these systems are usually based on the background knowledge of the transport network which can change during the time and in some cases can be missing or erroneous. GPS data and other information captured by the vehicles during their work can be exploited to update the network knowledge. This paper presents a novel approach, namely DeCoClu (Density Consensus Clustering), that aims at mining the topology of a public transport network by means of a consensus clustering density-based approach. In particular, the method exploits static information from time series of positioning signals (i.e., GPS data) to infer geographical locations of stops by means of a consensus clustering strategy based on a new distance function. Moreover, the logical pathway of a route (i.e., stops sequence) is defined by an Hamiltonian cycle. Experiments performed on real-data collections provided by a public transport company demonstrate the effectiveness of the proposed approach.

Tell me the bus – A new approach in developing applications for Public Transport end users

Autori: Arneodo F. Gastaldi D., Botta D.
Pubblicazione: Proceedings of the 10th ITS European congress, 16-18 June 2014, Helsinki (Finland)


In a city like Turin (less than 1 million inhabitants) more than 57% of Public Transport (PT) users are systematic clients; in other words, they take the same bus line twice a day every single workday. These persons know their PT lines and their itinerary much better than Public Transport Companies (or our algorithms) will ever do. In this paper a change of paradigm is proposed: instead of supplying people with complex forecast and aggregated data, we investigate the way to allow them accessing real-time, low level data in a practical and user friendly way. This will enable skilled passengers to put in practice their very personal experience in understanding the status of their PT line and, in short, make their on “forecasts”.

Estimation of public transport user behaviour and trip chains through Piedmont Region e-ticketing system

Autori: Arnone M., Dmastro T., Negrino C, Arneodo F., Botta D., Friuli G.
Proceedings of 14th ITS European Congress, Lisbon, Portugal, (Postponed).


Since 2009 Piedmont Region has started the design of a Public Transport (PT) integrated electronic ticketing system (BIP – Biglietto Integrato Piemonte) on the whole regional area. The project was aimed at increasing user accessibility through more flexible electronic ticketing. This paper focuses on a specific BIP application that, using data gathered in BIP environment, enables public stakeholders to have a detailed monitoring of PT service users’ behaviours, that represents a fundamental element for PT planning, programming and management. The user behaviour estimation, based on state of art literature, covers a whole regional area with heterogeneous transport modes and a complex transport network. Results were so promising that the algorithm has become a software component used in every regional BIP PT user behaviour analysis. The following chapters provide details on data, algorithms and tests and results developed to estimate travellers’ habits through the regional BIP platform.

Real-time data in public transport information and travel planning

Autori: Arneodo F., Botta D., Gagliardi G.
Pubblicazione: Proceedings of the 19th ITS World Congress, 22-26 October 2012, Vienna (Austria)


In this paper the project for the Piedmont Regional Traffic Supervisor (SVR) is described. It is developed by 5T company with the aim of traffic monitoring, forecast and control, over all the Piedmont Region. This is not a simple extension of the current Turin Metropolitan Traffic Supervisor, but a radical evolution of the concept in terms of data sources, data types, models realization criteria and traffic assignment algorithms. 5T is developing a new SVR able to evolve all the monitoring functions to the wide regional area extension, assuring, at the same time, a correct matching of all the traffic information at all the interfaces among the various municipalities. The extension and the different typology of the controlled areas require some specific technical choices that will be described in the paper. Besides, the wideness of the controlled area requires also an integration of classic “physical sensor“ with new “virtual sensors” (Floating Car Data – FCD): details about data acquisition, data completion, data fusion and harmonisation will be provided. Finally, a brief description of all the informative services that will be based on the traffic data generated by the SVR system, as well as a short review of some results, is also provided.

5T Srl is the non-commercial public company managing the traffic/PT/infomobility systems in the metropolitan area of Torino (counting more than 2M inhabitants). The 5T platform continuously grew up along years, and in 2006 it evolved into the Traffic Operation Centre of the Torino Winter Olympics. In the past years, 5T developed a state-of-the art integrated platform to let all its internal and external systems communicate each-other via standard and open technologies. Recently, we also chose the Google Earth and Google Maps tools as top level interfaces for the management of the whole distributed platform and to display to end-users the real-time data about traffic status, roadworks, parking occupation and so on. This document shortly describe some aspects of this experience.

Transmodel – NeTEx – EPTIS: a European Standard for Modelling and Exchanging Fares

Autori: Arneodo F. , Boureé K., Tibaut A.
Pubblicazione: Proceedings of the 22nd ITS World Congress, 6-9 October 2015, Bordeaux (France)

Interoperability between fare systems is an important step towards “seamless travel” and is a necessary condition for the efficient provision of passenger information on fares across transport modes. Achieving this goal presents a technical challenge and to help reach it the European project NeTEx/EPTIS proposes a standardised data exchange format for fares that can be used across Europe. The project specifies how to model the complexity of European fare structures, using a data model based on generic concepts that can represent the core elements of any fare system, independently of any specific set of concrete fare products offered for sale, and then derives a standard interface as an XML schema implementation. The European Reference Data Model for Public Transport (Transmodel), extended to cover the requirements of heavy rail, is used as a basis for the proposed fare model. An early implementation of NeTEx is achieved by the project BIPEx.

Piedmont Integrated Ticketing An innovative and strategic (and smart) approach

Autori: Arneodo F., Botta D., Migliasso D.
Pubblicazione: Proceedings of the 9th ITS European congress, 4-7 June 2013, Dublin (Ireland)


This paper describes the design and implementation of the Piedmont Integrated Ticketing project (BIP – Biglietto Integrato Piemonte) and its interoperability with any public service already supporting or willing to support this technology. The interoperation among different service operators will be assured by means of a single Regional Service Centre (the “CSR-BIP”) sharing data about services and customer usage with transport operators and Public Administration, by means of a standardized transfer data protocol (called BIPEx) compliant with the most up-to-date international standards. The same informative content will be used for dedicated informative services. Moreover, all services compliant to the BIP system will be accessed by users through a pure contactless smart card, with its Card Data Model, defining its content and the rules to access it. Customers will be able to change between Public Transport operators or other transport systems (i.e. car and bike sharing) and even cultural services (EDISU or PYOU Card) or regional museums, without the need to acquire a dedicated “ticket” for each. One centre, one protocol and a single smart card will enable one of the most integrated ticketing and informative service system ever.

Global MEC supporting automotive services: from multi-operator live trials to standardization

Authors: F. Arneodo (5T), Andrea Laganà (TIM), R. Lesca (5T), D. Sabella (Intel), altri
Publication: IEEE Conference on Standards for Communications and Networking (CSCN)

The automotive domain is a critical area for the introduction of MEC (Multi-access Edge Computing) infrastructure in 5G systems, since it can benefit from moving cloud computing capabilities and IT service environments to the edge of the network. However, it brings several challenges, especially the need for easy data exchange in multi-operator environments. This paper describes the first known development of edge federation/roaming for a vehicular use case. This has been carried out through a MEC live trial by several international players, including network operators, neutral hosts, car manufacturers, infrastructure vendors and technology providers. It also describes the role of standards, in particular 3GPP, ETSI MEC and GSMA’s OPG (Operator Platform Group) for enabling inter-working between operators and car makers to provide global MEC support for automotive services. Trials and standards can energize the deployment of 5G and so advance the benefits of MEC for end users.

An operational framework to integrate traffic message channel (TMC) in emergency mapping services (EMS)

Autori: Arco E., Ajmar A., Arneodo F. e Boccardo P.
Pubblicazione: European Journal of Remote Sensing, Volume 50, 2017


Traffic Message Channel (TMC) is a technology for delivering traffic information to vehicle drivers. Sources of traffic information typically include police departments, Traffic Information Centers (TICs), camera systems, traffic speed detectors, floating car data, so on. Both public and commercial TMC services are operational in many countries. TMC messages can be also exchanged among TICs formally using standard protocols. The term emergency mapping (EM) encloses all activities finalized to produce geographic data on the consequences of a natural or man-made events. Emergency mapping services (EMS) normally exploit satellite or aerial imagery in order to extract the extent of the area affected and the impact on local infrastructures. In this paper, the authors verify the impact of the integration of TMC information in routinary EMS, exploiting the flood event occurred in November 2016 in north-west Italy as a case study. After an introduction to the problem and a description of TMC technology and of EMS, all technical aspects related to the integration of the two services are deeply described. Extracted traffic events have then been integrated and compared with EM products generated for the event previously mentioned. Finally, opportunities, limits, future enhancement and refining are summarized in the conclusions.

Managing by Data the Governance of Regional Transport Network

Autori: Arneodo F. Botta D., Gagliardi G.
Pubblicazione: Proceedings of the 11th ITS European Congress, 6-9 June 2016, Glasgow (Scotland)


In this paper, a new approach to mobility management is described as well as the Italian reference scenario, where the transportation offer is changing towards the provision of different transportation services like public transport, car sharing, bike sharing, public transport for weak mobility demand areas. The role of the Public administration becomes crucial either for the funding of public transport or the governance of the mobility services portfolio, with a change of mobility concept towards a mobility as a service one. Piedmont Region, a Local Public Administration, charged 5T Company to realize a Regional Service Centre (CSR) for the Governance of the regional mobility services. An appropriate application of ITS and Business Intelligence techniques on CSR data will enable a Managing by data approach to reach this goal.

During last years, we assisted to an increment of mobility demand, implying the need of adequate infrastructure and efficient public transport. The deployment of informative services and Intelligent Transport Systems (ITS) assumed a fundamental importance to address mobility demand, strictly correlated to the territory characteristics. At the same time, mature Geomatic technologies, especially related to GPS differential positioning (both in real time and in post processing), mobile mapping systems (MMS), remotely sensed imageries (aerial, satellite and UAV platforms), archiving and management systems (Spatial Data Infrastructure – SDI) will play a crucial role. These applications to infomobility and ITS are described in this paper.
