歩道橋の夜間照明：低グレアと安心感

Show a pedestrian overpass at night, lit so that it feels safe rather than merely illuminated. Render the deck lit by a continuous linear source recessed into the underside of the handrail on both sides, washing the walking surface evenly from low down with no fitting visible at eye level and no glare toward oncoming pedestrians. Detail the light distribution so faces are legible — a second concealed source in the canopy soffit throwing soft light upward and back down, filling shadows so a person approaching can be recognised from the far end. Show the stair and ramp landings lit slightly brighter than the span so the arrival points read clearly from the street. Detail the light spill as controlled — nothing shining down onto the traffic lanes or into the apartments alongside, and the bridge structure itself reading as a dark silhouette with only its walking surface glowing. Include a person walking mid-span and another entering at the far end, both clearly visible. Show a wet deck after rain reflecting the line of light. Photorealistic, warm light on grey, calm, eye-level view along the deck.
