The work of preparing International Standards is

17、normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part

18、in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepa

19、re International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.In other circumstances, particularly when ther

20、e is an urgent market requirement for such documents, a technical committee may decide to publish other types of document: an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical experts in an ISO working group and is accepted for publication if it is approved by

21、more than 50 % of the members of the parent committee casting a vote; an ISO Technical Specification (ISO/TS) represents an agreement between the members of a technical committee and is accepted for publication if it is approved by 2/3 of the members of the committee casting a vote.An ISO/PAS or ISO

22、/TS is reviewed after three years in order to decide whether it will be confirmed for a further three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or ISO/TS is confirmed, it is reviewed again after a further three years, at which time it must either be transformed

23、 into an International Standard or be withdrawn.Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.ISO/TS 17444-1 was prepared by Technical Committee ISO

26、e systems (GNSS) both subject to a certain random behaviour that may affect the computation of the charges. Thus, in order to protect the interests of the different involved stakeholders, in particular Service Users and Toll Chargers, it is essential to define metrics that measure the performance of

27、 the system as far as computation of charges is concerned and ensure that the potential resulting errors in terms of size and probability are acceptable. These metrics will be an essential tool when establishing requirements for the systems and also for examination of the system capabilities both du

28、ring acceptance and during the operational life of the system.In addition, in order to ensure the interoperability of different systems it will be necessary to agree on common metrics to be used and on the actual values that define the required acceptable performances, although this is not covered i

29、n this part of ISO/TS 17444.Toll schemes take on various forms as identified in ISO/TS 17575 (all parts) and ISO 14906. In order to create a uniform performance metric specification, toll schemes are grouped into two classes, based on the character of their primary charging variable: Charging based

30、on discrete events (charges when a vehicle crosses or stands within a certain zone), and those based on a continuous measurement (duration or distance).The following are examples of discrete (event-based) toll schemes. Single object charging: a road section, bypass, bridge, tunnel, mountain pass or

31、even a ferry, charged per passage; most tolled bridges belong to this category. Closed road charging: a fixed amount is charged for a certain combination of entry and exit on a motorway or other closed road network; many of the motorways in Southern Europe belong to this category. Discrete road link

32、s charging: determined by usage of specified road links, whether or not used in their entirety.EXAMPLE German heavy goods vehicle (HGV) charge. Charging for cordon crossing: triggered by passing in or out through a cordon that encircles a city core, for example.EXAMPLE Stockholm congestion charging.

33、The following are examples of continuous toll schemes. Charging based on direct distance measurement: defined as an amount per kilometre driven.EXAMPLE Switzerlands HGV charge; US basic vehicle miles travelled approach. Charging based on direct distance measurement in different tariff zones or road

34、types: defined as an amount per kilometre driven, with different tariffs applying in different zones or on different road types. This is a widely discussed approach, also known as Time-Distance-Place charging, and is under consideration in many European countries. The pilot programme in Oregon is an

35、 example from North America. Time in use charge: determined by the accumulated time a vehicle has been in operation, or, alternatively, by the time the vehicle has been present inside a predefined zone.In all these examples of toll schemes, tolls may additionally vary as a function of vehicle class

36、characteristics such as trailer presence, number of axles, taxation class, operating function, and depending on time of day or day of week, so that, for example, tariffs are higher in rush hour and lower on the weekends.With this degree of complexity, it is not surprising to find that the attempts t

37、o evaluate and compare technical solutions for Service User charging have been made on an individual basis each time a procurement or study is initiated, and with only limited ability to reuse prior comparisons made by other testing entities.The identification of different types of schemes as propos

38、ed in ISO/TS 17575 (all parts) and their grouping in the mentioned two classes is described in Table 1, which also identifies the examples mentioned above.

40、 pricing timeCumulative distance charge Continuous Area pricing distanceCharging for cumulative distance (or time) in different zones (or by road type)Continuous Area pricing distanceNo toll schemes are purely continuous. At the very least, a system must be able to stop accumulating charges when it

41、leaves a jurisdiction in which a charge is due, and resume charging when it returns or enters another. Additionally, many Charging Schemes are set up so that the tariff is modified using discrete parameters, such as spatial zones, time spans, vehicle classes, etc. Under those circumstances, each uni

42、t of distance or time costs a different amount depending, for example, on whether it takes place inside or outside an area, such as a city, whether a trip takes place in rush hour or at night, or depending on what type of vehicle is used. In this part of ISO/TS 17444 references to a “continuous syst

43、em” have to be understood as those systems having some continuous behaviour even though they may also integrate some discrete nature. References to “discrete systems” are limited to those systems that are purely discrete.In these schemes, all the discrete parts (zones, cordons, events, time, vehicle

44、 class, etc.) that a system has to identify are translated into a particular tariff (e.g. price per kilometre) that has to be applied to the measured continuous variable (e.g. travelled kilometres) resulting in another continuous parameter, money.Among the different Interoperability Application Prof

45、iles defined in CEN/TS 16331, only Section Road Tolling has a purely discrete nature while the other four profiles have both discrete and continuous natures.Some features of discrete and continuous toll schemes that are of relevance for the definition of metrics proposed in this part of ISO/TS 17444

46、 are analysed below.Discrete toll schemesIn a discrete toll scheme, distinct events are associated with the identification of Charge Objects. It can be that a vehicle crossed a cordon, passed a bridge, was present in an area, or in an area on a given day. An event that takes place can either be corr

47、ectly recorded by the system or can be missed. However, there is also the possibility that an event is recorded even though it did not actually take place. This is summarized in the following matrix in Table 2.Table 2 Theoretical event decision matrix for discrete schemesEvent MatrixSystem detects C

48、hargeable EventYes NoChargeable Event takes placeYesCorrect ChargingMissed Recognition(Undercharging)NoFalse Positive(Overcharging)Correct Non-chargingIn this matrix there are two successful scenarios (Correct Charging and Correct Non-charging), and two unsuccessful (Missed Recognition and False Pos

49、itive). The unsuccessful scenarios have very different consequences. A Missed Recognition, i.e. a Chargeable Event that takes place but is not recorded by the system, implies an undercharging, as the Service User is not charged.vi ISO 2012 All rights reservedPD CEN ISO/TS 17444-1:2012ISO/TS 17444-1:2012(E)In the case of False Positive, a vehicle that is not using the toll domain is being charged for an event which did not take place. This implies an overcharging which is in violation of the legal rights of the Service User, and ultima
