Public transport - Road vehicle scheduling and control systems - Part 1: WORLDFIP definition and application rules for onboard data transmission
The present document specifies the choice and the general application's rules of an onboard data transmission bus between the different equipment for service operations and monitoring of the fleet. This applies to equipment installed onboard buses, trolleybuses and tramways only as part of a bus fleet operation. It excludes tramways when they are operated as part of a train, subway or metro operation. The equipment includes operations aid systems, automatic passenger information systems, fare collection systems, etc....
The equipment directly related to the functioning of the vehicle (driver dashboard, engine management, brake systems, door opening systems, etc...) are excluded from the scope of the present document and are dealt with in other standardisation bodies.
Two alternative transmission buses will be accepted. This document refers to the so called WORLDFIP bus. A second set of documents will be published for the second solution (so called CAN). There is no ranking between the two solutions and the selected bus system, between the two standardised alternatives, shall be subject to an agreement between each transport operating organisation and its equipment providers.
The present document refers to the so called OSI transmission model and covers OSI layers 1,2,7, the other layers are not used in our applications.
The present document covers the link between equipment inside a single vehicle. Although it could be applied to multiple vehicles, this application is not explicitly covered by this document.
The present document is the first part of a set of standards, related to the onboard transmission bus, which will comprise, for each allowed transmission bus, the following set of documents:
a) choice of the bus and general application's rules (EN 13149-1)
b) cabling specifications (EN 13149-2)
c) message's content specifications (prENV 13149-3)

This document supersedes ENV 13149-1:1999. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.
EN 13149-1 :2004 (E) 4 Introduction The present situation is the following: — A large number of Vehicle Scheduling and Control Systems (VSCS) do not use a data bus, resulting in — point to point data links with expensive cabling which cannot be preinstalled during the manufacturing of the vehicle, increasing the cost of the system — different proprietary transmission protocols which have to be implemented as and when required — difficulty in changing the provider of a given type of equipment as no compatibility exists between different providers of the same type of equipment — Some systems implement the VDV IBIS bus specification, but: — IBIS bus is very slow and no longer covers the need for high speed data transmission between equipment — IBIS bus is not an open system and does not cover some of the necessary messages — practically every VSCS manufacturer has been obliged to implement a second high speed data bus which is proprietary, resulting in no possibility of interchanging equipment with other manufacturers The buses, which are proposed by CEN/TC278, aim at avoiding the preceding difficulties with the following characteristics: — high capacity and high speed data bus — consistent workplan ensuring interoperability down to the message level — low cost solution — already standardised data bus — large number of already existing and future applications outside the VSCS area, ensuring the existence of equipment on the market, the progressive decrease of the cost of the necessary chips and the timelessness of the solution — existing chips and basic software up to and including the layer 7 of the ISO 7 layer communication model and existing developments tools, minimising the development costs The buses proposed by CEN/TC 278 have been chosen among others through a progressive selection process. This work took into account a flexible approach to the range of applications, the potential traffic loading under different operating circumstances and the definition of objective criteria for a transmission bus. The candidate buses were evaluated against the criteria in terms of performance, cost, industrial support and the existence of maintained documents. SIST EN 13149-1:2005

It will provide for the Physical, Data Link and Application layers. Power distribution may be provided within the same cable (on different wires) provided it does not contravene other requirements of this document. The following gives a brief summary of some of the main features of the network: — Essentially fieldbus linear topology — Periodic (Cyclic) data — A periodic (Events) data — Message and file transfer — Provides for control and information transfer — Deterministic performance-parametering of priority order and periods — Bus arbitration to ensure time critical data is undisturbed by less critical events and messages — Producer consumer model with provision to broadcast data — Open network — Self clocking — Half duplex — Medium redundancy possibility — Remote monitoring — Intelligent and non-intelligent devices — Distributed database — Error detection SIST EN 13149-1:2005
