Ecological Design Rules for Roadway Lighting
| 项目名称： | Ecological Design Rules for Roadway Lighting |
| 摘要： | Currently, the Ohio Department of Transportation (ODOT) designs roadway lighting in agricultural areas to produce adequate pavement illumination per the Traffic Engineering Manual (TEM), which cites industry standard IES RP-8. Typically, designers give little or no consideration to light trespass during roadway lighting design. All ODOT lighting installations run dusk-to-dawn with no programmed dimming or light curfews. An upcoming addition to the TEM will address light trespass in agricultural areas by recommending a light trespass illuminance limit of 0.1 foot-candle on agricultural fields. The proposed research will focus on the effects that LED lighting has on wildlife in ecologically sensitive urban and rural areas. Limited but ongoing academic research suggests that the quantity and spectra of LED lighting have negative (and occasionally positive) effects on terrestrial and aquatic ecosystems. These effects can influence individual species and the overall ecosystem health. Lighting that illuminates the roadway pavement is engineered lighting. Industry standards provide design pavement illuminance values, and it is difficult to deviate from these established engineering standards without reasonable justification. Well-executed research targeting this issue can serve as such justification for ODOT roadway lighting design changes that relate to ecological effects. The goal of this research is to establish design rules for roadway lighting in ecologically sensitive urban and rural areas. Objectives include determining the effects of roadway lighting on various wildlife areas including what type of animals are affected by light and how do attributes of the site play a role in the effect? |
