ITU-T Y.4116 (10/2017) i Recommendation ITU-T Y.4116 Requirements of transportation safety services including use cases and service scenarios Summary Recommendation ITU-T Y.4116 describes requirements for providing transportati
10、on safety services. The use cases and related service scenarios that are used to extract requirements for various IoT services and applications are also described in Recommendation ITU-T Y.4116. Accidents and disasters caused by the transportation means affect many lives and properties. Transportati
11、on safety can be influenced by defective vehicles (e.g., cars, trains, ships), environmental status (e.g., wind, snow, low temperatures), disruption to the transportation infrastructure (e.g., bridges, tunnels, roads) and human error. Transportation safety services based on Internet of things (IoT)
12、technologies can reduce the occurrence of accidents and disasters, and save the lives and damage to properties in the case of natural disaster.

ITU-T Y.4116 (10/2017) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector
15、(ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every fo
16、ur years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, th
17、e necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary.
18、However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the nega
19、tive equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTSITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the us
20、e of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation
21、, ITU had received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at http:/www.it

27、ice scenarios 1 Scope This Recommendation addresses requirements for providing transportation safety services based on Internet of things (IoT) technologies. These requirements are applicable to various means of transportation, e.g., road, railway, maritime and air. In this Recommendation, the conce
28、pts of transportation safety management according to the processing phases of IoT sensing data and the IoT sensing data necessary for safety management are introduced. An example of a decision-making hierarchy for transportation safety is also described. The requirements for transportation safety se
29、rvices are described and classified according to the ITU-T IoT reference model ITU-T Y.4000. Use cases and related service scenarios used to extract requirements for the various transportation safety services are described in Appendix I. Appendix II shows the relationship between the requirements pr
30、ovided in clause 7 and the use cases described in Appendix I. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation.

A list of the currently valid ITU-T Recommendations is r
32、egularly published. The reference to a document within this Recommendation does not give it, as a stand-alone document, the status of a Recommendation. ITU-T Y.4000 Recommendation ITU-T Y.4000/Y.2060 (2012), Overview of Internet of things. ITU-T Y.4101 Recommendation ITU-T Y.4101/Y.2067 (2017), Comm
33、on requirements and capabilities of a gateway for Internet of things applications. 3 Definitions 3.1 Terms defined elsewhere This Recommendation uses the following terms defined elsewhere: 3.1.1 gateway ITU-T Y.4101: A unit in the Internet of things which interconnects the devices with the communica
34、tion networks. It performs the necessary translation between the protocols used in the communication networks and those used by devices. 3.1.2 Internet of things ITU-T Y.4000: A global infrastructure for the information society, enabling advanced services by interconnecting (physical and virtual) th
35、ings based on existing and evolving interoperable information and communication technologies. NOTE 1 Through the exploitation of identification, data capture, processing and communication capabilities, the IoT makes full use of things to offer services to all kinds of applications, whilst ensuring t
36、hat security and privacy requirements are fulfilled. 2 Rec. ITU-T Y.4116 (10/2017) NOTE 2 From a broader perspective, the IoT can be perceived as a vision with technological and societal implications. 3.1.3 intelligent transport systems (ITS) b-ITU-T Y.4407: ITS is defined as systems utilizing the c
37、ombination of computers, communications, positioning and automation technologies to improve the safety, management and efficiency of terrestrial transport systems. 3.1.4 sensor b-ITU-T Y.4105: An electronic device that senses a physical condition or chemical compound and delivers an electronic signa
38、l proportional to the observed characteristic. 3.1.5 sensor node b-ITU-T Y.4105: A device consisting of sensor(s) and optional actuator(s) with capabilities of sensed data processing and networking. 3.1.6 thing ITU-T Y.4000: With regard to the Internet of things, this is an object of the physical wo
39、rld (physical things) or the information world (virtual things), which is capable of being identified and integrated into communication networks. 3.1.7 vehicle gateway platform (VGP) b-ITU-T F.749.1: VGP is the collection of ICT hardware and software in a vehicle operating as an open platform to pro
40、vide an integrated runtime environment for delivering the communications services of a VG. A VGP may also provide higher layer communications services such as interaction with the driver through the driver-vehicle access services and so on. Subsystems dedicated solely to vehicle operation are not co
41、nsidered part of the VGP. Supported applications/services include ITS and infotainment. 3.2 Terms defined in this Recommendation This Recommendation defines the following terms. 3.2.1 logistics satisfaction index: An index that reflects the degree of satisfaction of an owner of goods during a delive
42、ry process. NOTE For example, the logistics satisfaction index may be evaluated by considering the delivery experience of goods on the delivery route and the facilities of the delivery vehicles. 3.2.2 safety index: A numerical value indicating the health status of transportation infrastructure or ve
43、hicle at a given time. A low safety index means a critical health status of the transportation infrastructure or vehicle. NOTE 1 As an example of specific transportation infrastructure safety index, the type of road, such as mountain road or urban road, and the road health status, such as irregulari
44、ty and flatness, pothole and accident status, are evaluated for the road safety index. The road safety index can be adjusted in its evaluation by other parameters such as the type of vehicle and the driver characteristics, such as gender and age. NOTE 2 Clause I.1.2 provides information about the sa
45、fety index. 3.2.3 vehicle: A mean of transportation in air, maritime or surface environments. NOTE Examples of vehicle include cars, ships, flights, trains, unmanned aerial systems (UASs). 3.2.4 virtual sensor; soft sensor: A kind of sensor that uses information available from various measurements,
46、including process measurement parameters, to estimate the quantity of interest. A virtual sensor can process measurement parameters from physical sensors or other virtual sensors. NOTE 1 Some virtual sensors may convert parameters of physical domains to logical domain values, e.g., for specific moni
47、toring purposes. Also, some virtual sensors may realize this conversion among multiple domains, e.g., a “freezing“ sensor can be finally assembled from temperature sensor(s) and humidity sensor(s). NOTE 2 As an example, in case of transportation safety, the vibration of a vehicle and the elevation,
48、humidity, temperature and freezing status of the road, may be considered to create a virtual sensor for transportation safety. 3.2.5 transportation management centre: A centre for the management of transportation, including transportation safety. Rec. ITU-T Y.4116 (10/2017) 3 NOTE The main functions
49、 of this centre include observation of the safety status of vehicles and transportation infrastructure, and communication with vehicles and transportation infrastructure. 3.2.6 transportation service platform: A platform for transportation service support. NOTE The main functions of this platform include monitoring of the safety status of vehicles and transportation infrastructure, and execution of disaster simulations, in order to collaborate with a transportation management centre for tran
