Evaluation of Guardrail Embedded Lighting System in Trinidad, Colorado.

摘要

The City of Trinidad in southeast Colorado is located alongside an overpass for Interstate-25 that contains multiple on- and off-ramps in need of sufficient illumination. City planners wanted to avoid light spilling from the overpass onto the town and opted for a unique lighting design that involved embedding light-emitting diode (LED) lighting into the concrete barriers of the overpass. This design limited the amount of light spilling from the overpass by keeping the light concentrated to the roadway. This unique design is the only one of its kind known and no analysis of visibility had ever been conducted prior to this research.
