3 Standard contains requirements andguidance for the design of road lighting on the strategicmotorway and all purpose trunk road network, referredto hereafter as the strategic road network. publication of the new European and BritishStandards BS EN 13201 Road Lighting and BS 5489 Code of Practice for the Design of Road Lighting in2003 introduced significant changes to road lightingdesign criteria. This has necessitated the revision ofTD 30/87 Design of Road Lighting for All-PurposeTrunk Roads and TD 34/91 Design of Road Lightingfor Motorway trunk Roads.

4 These covered similartopics and this revised Standard consolidates them intoone standard for the design of road lighting on thestrategic road 5489 contains guidance and recommendationsto support BS EN 13201 and to enable designers ofroad lighting schemes to comply with it. This Standarddescribes how to apply BS EN 13201 and BS 5489 tothe design of road lighting for the strategic Standard should be read in conjunction withTA 96 Whole Life Cycle Code of Practice for Lightingon the Strategic Motorway and All Purpose trunk Standard sets out the design objectives andprocedures that shall be adopted for the design of roadlighting for the strategic road following aspects of road lighting are notincluded in this decision whether or not to provide roadlighting

5 (refer to TA 49 Appraisal of New andReplacement Lighting on the Strategic Motorwayand All Purpose trunk Road Network); design of lighting for long and short roadtunnels (refer to BS 5489-2 Code of Practice forthe Design of Road Lighting Part 2: Lighting ofTunnels and BD 78 Design of Road Tunnels); lighting levels and hours of operation(further advice on this subject will be availablefrom the Highways Agency from 2008); specification that is not directlyrelated to photometric performance (refer toother Standards and the relevant clauses fromMCHW-1); lighting power distribution Standard shall be used forthwith for thedesign of road lighting for the strategic road network.

6 Itshall be applied to both new lighting schemes andrenewals where lighting columns are to be a scheme is already under construction orcurrently being prepared and application of thisStandard would result in significant additional cost ordelay, the advice of the Overseeing Organisation shallbe this Standard the definitions in the followingstandards shall EN 13201-2 Road Lighting Part 2:Performance Requirements; 5489-1 Code of Practice for the Design ofRoad Lighting Part 1: Lighting of Roads andPublic Amenity 8 SECTION 3TD 34/07 August 20072/1 Chapter 2 Performance Requirements2.

7 PERFORMANCE road lighting shall be designed in accordancewith the recommendations of BS 5489-1 Code ofPractice for the Design of Road Lighting Part 1:Lighting of Roads and Public Amenity Areas, togetherwith the additional requirements set out in road lighting shall be designed and installedsuch that the installation will emit no direct light abovethe horizontal. criterion for lighting main carriageways onthe strategic road network is luminance based. The aimis to achieve a bright background (the road surface),with acceptable uniformity and glare, against whichobjects appear in silhouette.

8 The lighting shall complywith the quantifiable system performance requirementsset out in paragraphs and to criterion for lighting conflict areas on thestrategic road network, such as junctions, complex roadintersections, roundabouts and queuing areas, isilluminance based. The lighting shall comply with thequantifiable system performance requirements set out inparagraphs to road lighting should comply with thesubjective performance requirements set out inparagraphs to , so far as is arrangements for the strategic roadnetwork should generally be as described in of BS 5489-1, subject to the both in use and during maintenance is ofparamount importance (see Chapter 3 of thisStandard).

9 Andiicatenary lighting is only permitted in exceptionalcircumstances where it can be demonstrated thatit is the only practical System Performance Carriageways (strategic road network) lighting design shall be in accordance withthe recommendations of Clause 7 and Annex B ofBS 5489-1. The design objectives for the lightingof main carriageways are expressed inperformance terms using the five calculatedphotometric measures of maintained averageluminance, overall uniformity, longitudinaluniformity, threshold increment and design shall be based on dry road conditionsand shall use the ME-series of lighting classesgiven in Table 1a of BS EN 13201-2.

10 The wetroad MEW-series of lighting classes given inTable 1b of BS EN 13201-2 should not be usedunless specified by the Overseeing carriageways carriageways of motorways, dualcarriageway roads and single carriagewayroads; roads and free flow link roads atgrade-separated junctions andinterchanges, provided horizontal andvertical alignment complies with TD 9,including permitted relaxations; shoulders where the OverseeingOrganisation foresees hard shoulderrunning in the near shoulders (emergency lanes) shall bedesigned in accordance with Sub-Clause ofBS 5489-1.
