Trafiksäkerhets- och trygghetsaspekter i samspelet mellan gatumiljöns utformning och en mer energieffektiv belysning ; Traffic safety and perceptions of safety in the interaction between street environment and a more energy efficient lighting

Abstract

Projektets syfte var att studera trafiksäkerhetsaspekter i ny belysning och deras samspel med gatumiljön för oskyddade trafikanter. Projektet undersökte således belysningsförutsättningar, påverkan på cyklister, samspelet mellan belysning, trafiksäkerhet, gatumiljö och/eller andra effekter såsom trygghet, gällande tre olika ljuskällor och typer av belysning (kvicksilver 125W, keramisk metallhalogen 70W samt LED 25W) belägna i ungefär samma typ av gatumiljö på en gång- och cykelväg på Kungsholms strand i Stockholm. Resultaten visar att energiåtgången för LED är 28 % av traditionell kvicksilverbelysning och 49 % av keramisk metallhalogenbelysning. Denna studie visar att det är möjligt att få tillräckliga jämnhetsnivåer med LED-belysning men att detta är beroende av armaturens utformning, design och antalet stolpar per meter väg (i detta fall 15,3 m stolpavstånd). I denna undersökning påvisades inga skillnader i cykelhastighet för LED-belysning mellan dagsljus och mörker eller mellan olika typer av belysning. Analyser av trygghetsaspekter fungerade bra att göra baserat på enkla uppskattningar av hur bra belysningen fungerar (genom analys av digitala foton) och till exempel upplevelse av synbarhet stämmer mycket bra överens med de uppmätta fysikaliska belysningsmåtten. ; The project's aim was to study the traffic safety aspects of new lights and the interaction with the street environment for pedestrians and cyclists. This project investigated the lighting conditions, effects on cyclists, and the interactions between lighting, traffic safety, street environmental conditions and/or other effects such as perceptions of safety for three different light sources (mercury vapour 125W, ceramic metal halide 70W and LED 25W) located in about the same type of street environment on a pedestrian and bicycle path on Kungsholms strand in Stockholm. Results show that the energy consumption of the LED lighting is 28% of the traditional mercury vapour lighting and 49% of ceramic metal halide lighting. This study shows that it is ...
