Daytime Running Light

In several studies (Allen and Clark, 1964; Cantilli, 1970; Andersson, Nilsson and Salusjarvi, 1976; Allen, 1979; Attwood, 1981; and Rumar, 1981) the use of daytime running lights as a conspicuity device has been demonstrated to reduce the frequency of certain classes of motor vehicle accidents. What has not been determined is a method to derive a functional relationship between photometric output of daytime running lights and accident rates. The authors discuss their approach in the development of a model for relating derived figures of merit (based on photometric measurements) of some 45 unique daytime running light units and accident rate.

The ability for motorcycle to be detected is an important aspect in preventing crash involving motorcycle which is the most dominant vehicle in emerging countries. Widely referred as conspicuity, the crash factor is appropriately addressed by the introduction of mandatory daytime running light (DRL) law and is usually a success story in many parts of the world. In 2011, there was a motion introduced in the 64thsession of the United Nations Working Party on Lighting and Light-Signalling (GRE) for amber position lamp (APL) to be made mandatory on motorcycle as additional measure to improve motorcycle conspicuity. An experiment was designed to evaluate conspicuity level of motorcycle headlamp and tail lamp equipped with APL over motorcycle with present DRL setting (baseline). 15 participants simultaneously rated both motorcycles which are placed in parallel, at different distances and times of day. Motorcycle with APL was noticeably better detected from rear than front at 50 meter and 100 meter distance, as well as during night time and twilight. Median conspicuity level between night time and daytime and between night time and twilight was also distinctly different for rear lamp. These findings suggest that APL introduction could enhance motorcycle conspicuity especially for rear lamp position.

Daytime Running Light

Pemerintah Kabupaten Wonogiri melakukan evaluasi dengan UU No. 22 Tahun 2009 tentang menyalakan lampu utama bagi sepeda motor pada siang hari DRL (Daytime Running Light) guna mengatasi tingginya angka kecelakaan lalu lintas di Kabupaten Wonogiri. Pada penelitian ini pengambilan data primer langsung pada lokasi penelitian di Jalan Raya Wonogiri-Ngadirojo Km +3 Bulusulur, dengan rentang waktu tertentu yang ditentukan yakni penelitian dilakukan pada siang hari seperti penerapan yang diberlakukan pada peraturan ini, penelitian dilakukan pada hari-hari atau jam sibuk; hari Senin-Sabtu, Jam 06.30 – 08.30 WIB, Jam 10.00-11.30 WIB, Jam 12.00-13.30 WIB, Jam 15.30-17.00 WIB. Hasil pengamatan survei kendaraan bermotor (roda dua) di Jalan Wonogiri-Ngadirojo Km +3 Bulusulur, Wonogiri, tingkat partisipasi UU No. 22 tahun 2009 yaitu kewajiban pengendara sepedamotor untuk menyalakan lampu pada siang hari DRL (Daytime Running Light) yakni sebesar 96,65% (12.927 dari 13.375 kendaraan), dan yang tidak menyalakan lampu sebesar 3,35% (448 dari 13.375 kendaraan). Kecelakaan di Jalan Wonogiri-Ngadirojo Km +3 Bulusulur, Wonogiri antara tahun 2010-2013 menunjukan kenaikan dan penurunan namun, setelah tahun 2013 mengalami penurunan yang cukup signifikan dari 61 menjadi 27 pada tahun 2017. Hal tersebut bisa diakibatkan oleh tingkat kesadaran pengguna kendaraan bermotor utamanya menyalakan lampu untuk meningkatkan kewaspadaan. Meningkatnya kesadaran DRL (Daytime Running Light) dari tahun 2010 sebesar 46,96% menjadi 96,65% tahun 2017, di ikuti penurunan angka kecelakaan di Jalan Wonogiri-Ngadirojo Km +3 Bulusulur, Wonogiri dari 64 kejadian pada tahun 2013 menjadi 27 kejadian pada tahun 2017.
