Title Impressions of Lighting in Public Squares After Dark Type Journal Article
Year 2017 Publication Environment & Behavior Abbreviated Journal Env. & Behav.
Volume 43 Issue (up) 3 Pages 227-254
Keywords Psychology; public lighting; public safety; security; crime; perception; outdoor lighting
Abstract Lighting may affect impressions of public squares. Following studies on office interior lighting, the present research manipulated three modes of lighting—non-uniform–uniform, peripheral–overhead, and dim–bright—in three virtual squares. One study had 32 participants (15 men, 17 women) judge the spaciousness and privacy of each of the 24 public squares. A second study had a different group of 30 participants (16 men, 14 women) rate the appeal, safety from crime, and excitement of each square. Study 1 found that judged spaciousness increased with uniform and bright lighting, and that privacy increased with non-uniform, dim, and peripheral lighting. Study 2 found that rated appeal increased with uniform and bright lighting, as did safety from crime and excitement. Across the two studies, the uniform and bright lighting conditions contributed most to the kinds of favorable experiences people might expect to have in public spaces after dark.

Title Lighting for cycling in the UK—A review Type Journal Article
Year 2015 Publication Lighting Research & Technology Abbreviated Journal
Volume 49 Issue (up) 3 Pages 381-395
Keywords Lighting; Planning; Public Safety
Abstract While UK governments have recently sought to increase cycling activity, it remains a minority interest. One reason for this is the perceived danger of cycling on roads filled with traffic. There is statistical evidence to support this perception; for equal exposure, cyclists are more likely to be seriously injured than either drivers or pedestrians. Lighting has a role to play in reducing the hazards of cycling by enhancing the visibility and conspicuity of cyclists. Unfortunately, it is not at all clear that the current lighting regulations and recommendations for cycling and cyclists are the best that can be achieved or are even adequate for these purposes. A number of actions are suggested that should enable lighting’s contribution to the safety of cyclists to be realized.

Title Effects of road lighting on motorways Type Journal Article
Year 2009 Publication Traffic Injury Prevention Abbreviated Journal Traffic Inj Prev
Volume 10 Issue (up) 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.

Title Limitations in drivers' ability to recognize pedestrians at night Type Journal Article
Year 2005 Publication Human Factors Abbreviated Journal Hum Factors
Volume 47 Issue (up) 3 Pages 644-653
Keywords Vision; Public Safety; Adult; Age Factors; Aged; *Automobile Driving/psychology; Clothing; *Darkness; Female; Humans; Male; Middle Aged; Reaction Time; Task Performance and Analysis; Visual Perception
Abstract This study quantified drivers' ability to recognize pedestrians at night. Ten young and 10 older participants drove around a closed road circuit and responded when they first recognized a pedestrian. Four pedestrian clothing and two beam conditions were tested. Results demonstrate that driver age, clothing configuration, headlamp beam, and glare all significantly affect performance. Drivers recognized only 5% of pedestrians in the most challenging condition (low beams, black clothing, glare), whereas drivers recognized 100% of the pedestrians who wore retroreflective clothing configured to depict biological motion (no glare). In the absence of glare, mean recognition distances varied from 0.0 m (older drivers, low beam, black clothing) to 220 m (722 feet; younger drivers, high beam, retroreflective biomotion). These data provide new motivation to minimize interactions between vehicular and pedestrian traffic at night and suggest garment designs to maximize pedestrian conspicuity when these interactions are unavoidable.
