  Title Effects of electronic billboards on driver distraction Type Journal Article
  Year 2013 Publication Traffic Injury Prevention Abbreviated Journal Traffic Inj Prev  
  Volume 14 Issue 5 Pages 469-476  
  Keywords Adult; Advertising as Topic/*methods; *Attention; Automobile Driving/*psychology; Eye Movements; Humans; Middle Aged; Psychomotor Performance; Sweden; Time Factors  
  Abstract OBJECTIVE: There is an increase in electronic advertising billboards along major roads, which may cause driver distraction due to the highly conspicuous design of the electronic billboards. Yet limited research on the impact of electronic billboards on driving performance and driver behavior is available. The Swedish Transport Administration recently approved the installation of 12 electronic billboards for a trial period along a 3-lane motorway with heavy traffic running through central Stockholm, Sweden. The aim of this study was to evaluate the effect of these electronic billboards on visual behavior and driving performance. METHOD: A total of 41 drivers were recruited to drive an instrumented vehicle passing 4 of the electronic billboards during day and night conditions. A driver was considered visually distracted when looking at a billboard continuously for more than 2 s or if the driver looked away from the road for a high percentage of time. Dependent variables were eye-tracking measures and driving performance measures. RESULTS: The visual behavior data showed that drivers had a significantly longer dwell time, a greater number of fixations, and longer maximum fixation duration when driving past an electronic billboard compared to other signs on the same road stretches. No differences were found for the factors day/night, and no effect was found for the driving behavior data. CONCLUSION: Electronic billboards have an effect on gaze behavior by attracting more and longer glances than regular traffic signs. Whether the electronic billboards attract too much attention and constitute a traffic safety hazard cannot be answered conclusively based on the present data.

  Title Effects of road lighting on motorways Type Journal Article
  Year 2009 Publication Traffic Injury Prevention Abbreviated Journal Traffic Inj Prev  
  Volume 10 Issue 3 Pages 279-289  
  Keywords Lighting; Public Safety; Security  
  Abstract OBJECTIVES: The study has three objectives. The first is to investigate how the effect of road lighting on motorway accidents varies with different weather and road surface conditions. The second is to evaluate the future benefit of road lighting as a safety measure on motorways. The third is to evaluate the need for further research in the field of motorway lighting. METHOD: This article presents a cross-sectional study of the effects of road lighting on motorways mainly in The Netherlands. The main source of data is a Dutch database of accidents covering the period 1987-2006, but British and Swedish data are also used. RESULTS: The effect of road lighting on motorways is found to be greater in The Netherlands than in Great Britain or Sweden. Reasons for this are not known. Effects are found to vary according to background characteristics and are lesser during precipitation than during fine weather and on wet road surfaces than on dry surfaces. No effect of road lighting is found during fog. Collision with light poles constitutes a large number of accidents on lit motorways and reduces the safety effect of road lighting. CONCLUSIONS: The effect of road lighting on injury accidents during darkness is found to be very high (-49%) on Dutch motorways. However, the effect seems to vary between countries. Collisions with light poles reduce the effect of road lighting. Road lighting will probably be an effective safety measures on motorways for many years. In the long term, however, the benefit of road lighting will probably be reduced along with the implementation of new vehicle and road technology. Modern technology permits a continuous adaptation of luminance levels to optimize the effect of road lighting on safety while at the same time minimizing energy consumption. However, more detailed knowledge concerning the effects of road lighting at different lighting levels is needed in order to use this technology effectively. Alternative or additional measures like LED guide lights and light road surfaces also need to be evaluated.
