Abstract: On July 15th 2011 the Flemish motorway lighting changed, introducing nine types of lighting changes to the motorway network. The goal of this study is to measure the effects of this new so called 'Flemish Lighting Vision'. This goal will be achieved in this study by using a before-after study with as comparison group daytime accidents. The main analysis techniques used here are correction for the trend analysis and meta-analysis of crash data. The accident data was provided through police records of injury accidents that occurred on Flemish motorways between the beginning of 2006 and the end of 2012. The study mainly indicates that the number of crashes between before and after the introduction of the lighting changes did not significantly increase or decrease, taking into account general traffic trends. Yet there is a noticeable crash reduction on dynamically lit parts of the motorway network of 23%. On the same parts the number of rear-end crashes is reduced by 41%. From the analysis it also becomes clear that the unlit parts of the motorway network are equally as safe as during the before period.
