It is noted that there exists strong positive correlations between the maximum pupil illuminance transition and the EDVO. It is suggested that the current stopping sight distance at the tunnel portals should be increased by 20–30 m to accommodate the general visual oscillation phenomenon.]]> Fri, 26 Sep 2014 14:24:32 GMT https://trid.trb.org/View/1322055 Interactions among Light Source Luminance, Illuminance and Size on Discomfort Glare https://trid.trb.org/View/1224023 Thu, 20 Dec 2012 09:14:52 GMT https://trid.trb.org/View/1224023 LED Street Lights in Alaska https://trid.trb.org/View/1217177 Fri, 19 Oct 2012 15:52:41 GMT https://trid.trb.org/View/1217177 Design of LED Freeform Optical System for Road Lighting with High Luminance/Illuminance Ratio https://trid.trb.org/View/1102793 Thu, 26 May 2011 10:29:07 GMT https://trid.trb.org/View/1102793 Design and Evaluation of Effective Crosswalk Illumination https://trid.trb.org/View/1101749 Thu, 26 May 2011 10:29:07 GMT https://trid.trb.org/View/1101749 Study of Intensity of Illuminance Required By Pedestrian Lighting https://trid.trb.org/View/890323 Fri, 19 Jun 2009 09:29:03 GMT https://trid.trb.org/View/890323 Design and Evaluation of Effective Crosswalk Illumination https://trid.trb.org/View/890121 Tue, 02 Jun 2009 14:47:57 GMT https://trid.trb.org/View/890121 Headlamp Parameters and Glare https://trid.trb.org/View/884017 Thu, 19 Feb 2009 14:42:17 GMT https://trid.trb.org/View/884017 Informational Report on Lighting Design for Midblock Crosswalks https://trid.trb.org/View/860048 Tue, 27 May 2008 16:09:34 GMT https://trid.trb.org/View/860048 Minimum Retroreflectivity Levels for Blue and Brown Signs with and without Glare and Roadway Lighting https://trid.trb.org/View/847637 Wed, 21 May 2008 07:05:50 GMT https://trid.trb.org/View/847637 Relationship of Vertical Illuminance to Pedestrian Visibility in Crosswalks https://trid.trb.org/View/848314 Fri, 28 Mar 2008 08:16:29 GMT https://trid.trb.org/View/848314 Precast Concrete Parking Structure Lighting Study https://trid.trb.org/View/849105 Fri, 01 Feb 2008 08:18:41 GMT https://trid.trb.org/View/849105 Influence of Vertical Illuminance on Pedestrian Visibility in Crosswalks https://trid.trb.org/View/777133 Fri, 03 Mar 2006 10:48:57 GMT https://trid.trb.org/View/777133
