In addition, when the illumination increased, pupil size decreased (0.7 lx > 2 lx > 5 lx). Also, driver’s discomfort increased when pupil size was small, and theta waves were high. This discomfort may cause reduced attention and safety of the driver. These results can be applied to design and development of headlamps. Further investigation is necessary with adopted methodology to evaluate other headlamps in different illumination conditions. Practitioner Summary: This study evaluated pupil size and electroencephalography under different glare source (halogen, HID and LED) and illumination levels (0.7, 2 and 5 lx). Driver’s discomfort increased when pupil size was small, and theta waves were high. This discomfort may cause reduced attention and safety of the driver.]]> Wed, 27 Sep 2017 10:17:42 GMT https://trid.trb.org/View/1481349 Benefits of Intelligent Headlamp Technologies to Pedestrian Safety at Roundabouts https://trid.trb.org/View/1142130 Tue, 03 Jul 2012 08:51:26 GMT https://trid.trb.org/View/1142130 Pedestrian Safety Margins Under Different Types of Headlamp Illumination https://trid.trb.org/View/920035 Thu, 24 Jun 2010 07:28:18 GMT https://trid.trb.org/View/920035 Survey of the Current State of Vehicle Headlamp Aim https://trid.trb.org/View/909881 Mon, 24 May 2010 14:08:40 GMT https://trid.trb.org/View/909881 Strategies for Optimizing Headlamp Illumination and Visibility Along Curves https://trid.trb.org/View/911880 Fri, 19 Feb 2010 10:56:50 GMT https://trid.trb.org/View/911880 Subjective Color Preferences of Common Road Sign Materials Under Headlamp Bulb Illumination https://trid.trb.org/View/911881 Fri, 19 Feb 2010 10:56:48 GMT https://trid.trb.org/View/911881 Photometric Indicators of Headlamp Performance https://trid.trb.org/View/907526 Mon, 28 Dec 2009 08:29:26 GMT https://trid.trb.org/View/907526 Benefits of Head Lamp Leveling and Cleaning for Current U.S. Low Beams https://trid.trb.org/View/897662 Wed, 12 Aug 2009 12:46:39 GMT https://trid.trb.org/View/897662 Sensitivity Analysis of Headlamp Parameters Affecting Visibility and Glare https://trid.trb.org/View/886695 Mon, 13 Apr 2009 14:59:30 GMT https://trid.trb.org/View/886695 Visual Benefits of High-Intensity Discharge Automotive Forward Lighting https://trid.trb.org/View/884020 Thu, 19 Feb 2009 14:42:17 GMT https://trid.trb.org/View/884020 Visual Benefits of Blue-Coated Lamps for Automotive Forward Lighting https://trid.trb.org/View/884019 Thu, 19 Feb 2009 14:42:17 GMT https://trid.trb.org/View/884019 Optimization of Forward Lighting: Headlamp Intensity and Visibility Along Curves https://trid.trb.org/View/876746 Tue, 30 Dec 2008 12:37:54 GMT https://trid.trb.org/View/876746 Power Distribution for the All-LED Circuit: An Overview of How to Set Up the Backbone of an All-LED Airfield Lighting System https://trid.trb.org/View/810137 Fri, 20 Jul 2007 09:56:28 GMT https://trid.trb.org/View/810137 Recent Trends in the Performance of Tungsten-Halogen and HID Low Beams in the U.S. https://trid.trb.org/View/805482 Fri, 30 Mar 2007 07:01:03 GMT https://trid.trb.org/View/805482
