The Research Of Road Lighting In Three-dimensional Transportation Based High-speed Road Of Which Main Roads And Auxiliary Roads Are Parallel

Because of the advantages of overpasses, China is carrying out the development of three-dimensional transportation, including high-speed road of which main roads and auxiliary roads are parallel. However the researches of road lighting in China are based on the model of ordinary roads. This research’s purpose is to abound basis and proposal of road lighting design.The study focused on inducting the types of three-dimensional transportation, building typical road sections, and finally bounding basis and proposal of road lighting design, In the research, by to document search, defining variables in research, I inducted existing achievement about road lighting and integrated normal road and three Three-dimensional transportation; by site measuring, subjective evaluation and software analysis of three-dimensional transportations in Beijing, the necessity of the research is curtained; By building digital models of three-dimensional transportation in DIALUX, I analyzed the issues about illuminance, glare, surround ratio and etc, put forward the most rational arrangement of road lights; by digital stimulation of a road in 04 district in Sino-Singapore Eco-city, the maneuverability of the study is verified.The paper did explanation and innovation on urban road lighting, abounded the research about road lighting in China, and put forward way of road lights arrangement and design suggestion by the ideas of“low carbon”and green lighting and finally offers the theoretical basis of road lighting.
