Page 50LIGHTINGThe clear desert night skies have oftenprovided the impetus for Phoeniciansto create their own magical lightingtreatments. The lighting of the MillAvenue Bridges, the wrapped palms inthe Phoenix Civic Plaza, or the coloredlights on the exterior of the ScienceMuseum are but a few of such treatmentswhich bring a sense of wonder toour cities. However, within transportationsystems, we rely on light for otherreasons besides magic; we rely on it forsecurity, wayfinding, and connecting toplaces within neighborhoods.While it is understood that the publicwill look to lighting to create consistent,secure means to navigate the light railsystem, it should also be acknowledgedthat they will look for lighting to continueto create special nighttime placeswithin their communities. Therefore,the architectural design process shouldinclude a lighting designer as part ofthe project team to ensure that lightingis integral, not an afterthought. It is furtheranticipated that a number of publicart works could build on the conceptsof lights in the desert.Some of the lighting fixtures that willbe included are street lighting, parkinglot lights, station lights, security lights,bollards, and landscaping lights.Urban DesignPerformance Criteria∆ Meet or exceed minimum requirementsfor exterior light levels asspecified by the IlluminatingEngineering Society (IES) and followlocal CPTED ordinances.∆ Use lighting to provide a sense ofscale and orientation.∆ All lighting systems should bedesigned for ease of maintenance,energy-efficient operation, highestquality of light, and architecturalcompatibility with system-widestandards.∆ Select fixture types based on highreliability and the availability offuture replacement components.Parts must be readily available tomaintenance crews so that lightingquality will be maintained.∆ Site light fixtures in easy to maintainlocations.∆ Design station lighting to provide awelcoming approach to the stationarea and a warm ambience withinthe station itself.∆ Look at light pole design during theOCS pole selection process toensure that the design of the OCSpole and the design of the stationlight poles are integrated parts ofthe system identity.∆ Avoid fixtures with minimal aestheticqualities such as cobra heads.∆ Evaluate OCS poles for use inattaching new light fixtures; minimizethe introduction of additionallight poles by using the OCS poleswhen possible.∆ Evaluate the conditions of existingstreet lighting along the LRT route;if in-fill light fixtures are required,conform to the existing light polearchitecture and lamp types; relocateand reuse existing fixtureswhen possible.∆ Scale fixtures appropriately tocanopies and the pedestrian level ofactivity.∆ Minimize shadows and shadowyhiding places, but avoid excessiveglare and light spillage into nearbyhomes and businesses.∆ Provide designs having even andconsistent levels of light for eachtype of system and location. Avoidtoo much light (hot spots) and too
URBAN DESIGN GUIDELINESlittle light (dark spots) in the spacingand arrangement of light fixtures.∆ Employ dark sky principles; useaccent lighting of landscape elementssparingly and appropriately.∆ Use unobtrusive full-cutoff luminariesto light park-and-rides and themaintenance and storage facility.Light these areas typically from theouter perimeter in, to minimizelight spill beyond the edge of lots.Safe, Pleasant Station Platform PedestrianArea Lighting∆ Utilize metal-halide lamps withceramic arc tubes for a strong combinationof color, life, and efficiency.Lamps should all be by the samemanufacturer for ease of replacementand maintenance.Importance to UsersExperienceForm: HighThe appearance of lighting fixtures andthe quality of light produced is veryimportant to conveying a high qualityimage of the system.Function: HighLighting must function to provide asafe, secure, and convenient experiencefor the user, particularly when LRTpatrons are on foot at stations, stationareas, parking lots, etc. Night lighting isthe first line of defense in supportingCPTED (Crime Prevention throughEnvironmental Design) standards forsafe, and secure public spaces.CostInteresting Light and ShadowUnique Character Accents1%% of Overall Budget15%% Urban Design Affects ElementDevelop a System of Fixture Designs thatRelate to System IdentityPage 51
