Vesolje - Ugotavljanje položaja z uporabo sistema globalne satelitske navigacije (GNSS) pri inteligentnih transportnih sistemih (ITS) v cestnem prometu - 1. del: Definicije in sistemsko-tehnični postopki za določanje in ocenjevanje zmogljivosti
Civilne uporabe ugotavljanja geografskega položaja so v hitrem razvoju. Zadnja tržna analiza za sisteme GNSS prikazuje dve glavni področji uporabe, ki si skupaj delita praktično celoten trg:
– inteligentni transportni sistemi (ITS), predvsem na področju sistemov ITS v cestnem prometu,
– lokacijske storitve (LBS), ki so na voljo v pametnih telefonih in tabličnih računalnikih.
Če sistem ITS v cestnem prometu zahteva ugotavljanje položaja z uporabo sistema GNSS, kar velja za večino takih sistemov, se pojavi vprašanje glede izbire vrste sistema GNSS ali sprejemnika ter minimalnih zahteve glede zmogljivosti sistema GNSS, ki so potrebne za izpolnjevanje končnih zahtev sistema ITS na ravni uporabnika. Za izpolnjevanje teh zahtev sistem vključuje obdelovalni aplikacijski modul, ki uporablja izhode (PVT = položaj – hitrost – čas) terminala sistema GNSS za zagotavljanje storitve s podano zmogljivostjo delovanja od začetka do konca. Slednja je posledično odvisna od kakovosti izhodov sistema za ugotavljanje položaja, ki se zelo razlikuje glede na pogoje delovanja sistema, in samega delovanja aplikacijskega modula.
Glavni sistemi ITS, ki jih te težave zadevajo:
– sistemi cestninjenja, ki uporabljajo sistem GNSS (na javnih cestah, parkiriščih, v urbanih območjih …),
– sistemi za lokalizirane klice v sili (eCall),
– elektronski tahografi,
– taksimetri,
– transportni sistemi za regulirani tovor (nevarne snovi, živali itd.),
– sistemi avtomobilskega zavarovanja glede na prevoženo razdaljo,
– sistemi cestnega upravljanja, sistemi prometnih informacij,
– napredni sistemi za pomoč voznikom (ADAS),
– drugi sistemi.
Nekateri sistemi ITS v cestnem prometu se obravnavajo kot ključni za zagotavljanje varnosti, ker lahko odpoved teh sistemov povzroči smrt ali poškodbe, drugi pa kot ključni za zagotavljanje odgovornosti, ker vključujejo finančne ali regulativne vidike. V nekaterih primerih je razvoj teh sistemov predmet uradnega postopka certificiranja/homologacije. Predvsem pri teh sistemih je treba dokazati, da izpolnjujejo zahteve glede kakovosti delovanja od začetka do konca.
Trenutno ne obstaja norma ali standard, ki bi podpiral tak postopek certificiranja, hkrati pa je ocenjevanje delovanja ugotavljanja položaja z uporabo sistema GNSS težko izvedljivo.
Cilj tega standarda EN je zapolniti to vrzel z zagotavljanjem pristopa za upravljanje vidikov delovanja sistemov ITS v cestnem prometu, ki temeljijo na ugotavljanju položaja in jasno razlikujejo vlogo terminala za ugotavljanje položaja in aplikacijskega modula.
Podaja standardne opredelitve metrik delovanja za izhode terminala sistema GNSS za ugotavljanje položaja, ki jih uporabljajo sistemi ITS v cestnem prometu, opredelitve različnih elementov, ki jih je treba upoštevati, ko se določa operativni scenarij z metodo za opis okolja, ter postopke za usklajevanje rezultatov preskusov na različnih komponentah sistema za namene ocenjevanja delovanja od začetka do konca.
Dokument lahko uporabljajo različni deležniki v različne namene:
– lahko ga uporablja preskusni laboratorij za ocenjevanje delovanja celotnega sistema ITS v cestnem prometu, ki vsebuje dani terminal za ugotavljanje položaja in je namenjen uporabi v takem primeru;
– lahko ga uporablja razvijalec sistema ITS v cestnem prometu, ki želi izbrati ustrezno tehnologijo za ugotavljanje položaja, ki je skladna z delovanjem njegove aplikacije, ali želi prilagoditi algoritem aplikacije glede na delovanje terminala;
– lahko ga uporablja proizvajalec terminala za ugotavljanje položaja, ki želi razviti specializiran nabor namenskih terminalov za take aplikacije ali ponuditi enega od svojih izdelkov razvijalcu sistema ITS v cestnem prometu.

— Part 1: Definitions and system engineering procedures for the establishment and assessment of performances — Part 21: Performance assessment tests of GNSS-based positioning terminals — Part 31: Security aspects of performance assessment tests According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.
1 In preparation. SIST EN 16803-1:2016
Figure 1 — The two main components of a Road ITS system The main Road ITS systems concerned by this issue are: — GNSS-based Road User Charging systems (road, parking zone, urban…); — localized emergency calls (eCall); — electronic tachograph; — taximeter; — regulated freight transport systems (hazardous substances, livestock, etc.); — “Pay-as-you-drive” insurance; — road management systems, traffic information systems; — advanced Driver Assistance Systems (ADAS); — etc. Some Road ITS systems are considered as “safety critical”, because their failure may cause human death or injury and others are “liability critical”, because they include financial or regulatory aspects. In some cases, their development is subject to an official certification/homologation process.
Figure 2 — Logic of the overall performance management approach The starting point of any performance management of a Positioning-based road ITS system should be the definition and clear statement of the E2E performances which are targeted by the system to design and/or test, as expressed by the customer. In the context of this European Standard, the system breakdown into components is the one that has been introduced above: — The GNSS-based positioning terminal (GBPT) — The Road ITS application The interface between these two components is assumed to be the PVT information, together with some auxiliary information, for instance Integrity information if the GBPT is designed to support this kind of feature. Performance requirements are generally stated as requirements on the outputs of a given system component, assuming that the other components feeding it with input information do respect their own performance requirements. SIST EN 16803-1:2016
Figure 3 — Generic performance allocation process The performance requirements of the Road ITS application are actually the same ones as the system E2E performance requirements, but expressed under the condition that the GBPT respects certain performances requirements. NOTE Depending on the application, performance requirements may need to be put only on the position output or only on the velocity output by the GBPT. Due to the specificities of GNSS performances, which have to be defined statistically and which are highly dependent on the operational conditions, margins should be planned in the performance allocations, in order to allow the system to meet its performance requirements, even when, in certain conditions, one of its component does not strictly meet its own requirements. 1 Scope EN 16803-1 addresses the final stage of the performance management approach, i.e. the assessment of the whole Road ITS system performance equipped with a given GBPT, using the Sensitivity analysis method. EN 16803-1 addresses the assessment of GBPT performance, since it identifies and defines the positioning performance features and metrics to be used in the definition of the GBPT performance requirements. This EN gives definitions of the various items to be considered when specifying an Operational scenario and provides a method to compare finely two environments with respect to their effects on GNSS positioning performance. This EN gives definition of the most important terms used all along the document and describes the architecture of a Road ITS system based on GNSS as it is intended in this standard.
