1、DRAFT FOR DEVELOPMENT DD ENV 12694:1997 Public transport Road vehicles Dimensional requirements for variable electronic external signs ICS 35.240.60DDENV 12694:1997 This Draft for Development, having been prepared under the direction of the Electrotechnical Sector Board, was published under the auth

2、ority of the Standards Board and comes into effect on 15 September 1997 BSI 04-1999 ISBN 0 580 28447 6 National foreword This publication is not to be regarded as a British Standard. It is being issued in the Draft for Development series of publications and is of a provisional nature because the lev

3、el of innovation on the subject is currently high. It should be applied on this provisional basis, so that information and experience of its practical application may be obtained. Comments arising from the use of this Draft for Development are requested so that UK experience can be reported to the E

4、uropean organization responsible for its conversion into a European Standard. A review of this publication will be initiated2 years after its publication by the European organization so that a decision can be taken on its status at the end of its three-year life. The commencement of the review perio

5、d will be notified by an announcement in Update Standards. According to the replies received by the end of the review period, the responsible BSI Committee will decide whether to support the conversion into a European Standard, to extend the life of the prestandard or to withdraw it. Comments should

6、 be sent in writing to the Secretary of BSI Technical Committee EPL/278, Road transport informatics, at389 Chiswick High Road, London W44AL, giving the document reference and clause number and proposing, where possible, an appropriate revision of the text. Cross-references Attention is drawn to the

7、fact that CEN and CENELEC Standards normally include an annex which lists normative references to international publications with their corresponding European publications The British Standards which implement international or European publications referred to in this document may be found in the BS

After two years the members of CEN will be requested to submit their comments, particularly on the question whether the ENV can be converted into an European Standard (EN).

At the present time there exists a set of technologies for such signs (ex: dot matrix, flaps, films, LCD, etc.). 2 Definitions For the purposes of the present standards the following definitions will apply: variable external sign device fitted on urban and long distance public tra

21、nsport vehicles which informs the users about the details of operation of that particular vehicle destination information variable information visible from outside the vehicle which displays details of the operation of that vehicle such as: line identification, destination, route taken, terminus or

The aim of the standards shall not be to define the individual technologie

26、s. However every system shall guarantee good visibility and ease of reading, also in adverse weather conditions such as fog, snow, strong sun light, etc. These signs shall respect a set of given conditions, in order to be compatible with the characteristics of the vehicle, to allow some interchangea

27、bility and to be functionally efficient. 3.1 Location and display characteristics and content 3.1.1 Headsign The headsign shall be located above the windscreen or on the upper part of it. It is strongly recommended that looking from the ground the line number shall be on the left and the destination

28、 on the right. If there is only the line number it is strongly recommended that the sign shall be placed in the centre or on the left as seen from the ground. 3.1.2 Sidesign The sign shall be located near the first entrance door or above the door. The line identification shall be on the left of the

29、sign, as seen from the ground. In positioning the sign, regulations concerning headroom above seats, if any, shall be complied with.ENV12694:1997 4 BSI 04-1999 3.1.3 Rearsign As seen from outside the vehicle, the sign shall be located in the centre or the right (left for U.K.), on the rear upper par

30、t of the vehicle. It displays at least the line identification. 3.2 Characters 3.2.1 Generalities For legibility purposes, the character type (letters and numbers), shall be as close as possible to Helvetica. It is recommended to use a reduced number of characters and to avoid alternating messages.

31、Information can be displayed on one or more character lines. It is recommended that a mixture of upper and lower case letters shall be used. 3.2.2 Colours Yellow or white on a black background are recommended. However other colours can be used for particular needs, taking into account that the lumin

32、ous green and red, corresponding to standards for traffic lights and emergency colours, should be avoided. 3.2.3 Classes of character heights (expressed in capital letters): 3.2.4 Recommendations It is recommended that the character heights chosen conform to the following tables: CLASS A = 70mm. CLA

33、SS B = 100mm. CLASS C = 125mm. CLASS D = 150mm. CLASS E = 180mm. CLASS F = 200mm. CLASS G = 240mm. CLASS H = $ 300mm.

36、hese classifications of characters without restricting the technologies used shall be comprised between the following figures: In order to allow maximum flexibility, in the choice of the sign it is recommended that Body Manufacturers provide the largest space possible subject to the above mentionned

37、 specifications. 3.4 Electric connections When a European standard exists for an on board transmission bus for road public transport vehicles and is implemented in the vehicle, then the sign shall be either directly connected to this bus or connected to this bus through a special control unit. 3.5 S

38、ign illumination and mounting The displays shall be easy to install, substitute and maintain. The substitution of the lights should not entail the disassembling, even partial, of the signs. The lighting system shall not illuminate the external glass in front of the sign but only the surface of the s

39、ign. The viewing windows shall be of the same dimensions or bigger than the destination sign to provide an easier reading. It is recommended to leave a space of50mm.between the sign and the sides to permit easy installation and maintenance (working space). Mini-bus front space dimensions: minimum 1
