Abstract |
Experimental evidence about the relationship between outdoor lighting and crime was examined in Part 1 of this work. Although the presence of light tends to allay the fear of crime at night, the balance of evidence from relatively short-term field studies is that increased lighting is ineffective for preventing or deterring actual crime. In this second part, available evidence indicates that darkness inhibits crime, and that crime is more encouraged than deterred by outdoor lighting. A new hypothesis is developed accordingly. Additional quantitative evidence supports the hypothesis. Excessive outdoor lighting appears to facilitate some of the social factors that lead to crime. The proliferation of artificial outdoor lighting has been fostered with little regard for the environmental consequences of wasteful practice. Widely observed exponential increases in artificial skyglow indicate that the growth of outdoor lighting is unsustainable. The natural spectacle of the night sky has already been obliterated for much of the population of the developed world. Copious artificial light has transformed civilisation, but increasing knowledge of its adverse environmental, biological and cultural effects now justifies large overall reductions in outdoor ambient light at night as well as in its waste component. ‘Good’ lighting has to be redefined. Moderation of outdoor ambient light levels may reduce crime in due course, as well as limiting the adverse environmental effects. Lighting controls might provide a means of limiting urbanisation and urban sprawl. National crime prevention policies, laws, lighting standards, architectural use of light and urban planning practice appear in need of fundamental changes. |

Abstract |
This paper gives some background to claims of benefit from road lighting and why large beneficial claims may be suspect. It places this in the context of general concerns about the unreliability of claims in science using knowledge gained, particularly from investigations in the field of health-care. It points to the need to plan, proceed and check science in unbiased and rigorous ways. It gives recommendations for more transparency, asks for clear protocols to be produced in advance, that clear reports are written which follow appropriate reporting guidelines and that the data is accessible. |

Abstract |
This pilot project study was intended to demonstrate that assessing the adequacy of an area’s pedestrian lighting need not be an expensive, time-consuming, or overly complicated process. Though the discussion of methods of pedestrian lighting can become quite technical and involved, as demonstrated in a 2016 IPA report on the topic, “Delaware Transportation Lighting Inventory & Assessment” (http://www.ipa.udel.edu/publications/transportationlighting-2016.pdf), simply observing and recording light levels in a given study area is quite straightforward. |

Abstract |
1. Introduction
1.1 Stating the problem: security versus climate and economic challenges
Public street lighting as a public service is often taken for granted. However, its impact on the nocturnal perception of public space should not be underestimated. It encourages people to get out, feel safe, and be safe. Indeed, Welsh and Farrington suggest that public lighting enhances social control, cohesion, and a feeling of community pride (Welsh & Farrington, 2008b). According to (Williams, 2008), this is due to the special meaning attached to the darkness of night in society. It is associated with changes in social norms and values, transgression, the release of social control, feasting, drinking, and pleasure. Meanwhile, the darkness of night generates unpredictability, uncertainty and, therefore, fear. Illuminating the night chases away these feelings; people feel reassured and safer (Schivelbusch, 1995). |

Abstract |
Adaptive headlights swivel with steering input to keep the beams on the roadway as drivers negotiate curves. To assess the effects of this feature on driver's visual performance, a field experiment was conducted at night on a rural, unlit, and unlined two-lane road during which 20 adult participant drivers searched a set of 60 targets. High- (n=30) and low- (n=30) reflectance targets were evenly distributed on straight road sections and on the inside or outside of curves. Participants completed three target detection trials: once with adaptive high-intensity discharge (HID) headlights, once with fixed HID headlights, and once with fixed halogen headlights. Results indicated the adaptive HID headlights helped drivers detect targets that were most difficult to see (low reflectance) at the points in curves found by other researchers to be most crucial for successful navigation (inside apex). For targets placed on straight stretches of road or on the outside of curves, the adaptive feature provided no significant improvement in target detection. However, the pattern of results indicate that HID lamps whether fixed or adaptive improved target detection somewhat, suggesting that part of the real world crash reduction measured for this adaptive system (Highway Loss Data Institute (HLDI), 2012a) may be due to the differences in the light source (HID vs. halogen). Depending on the scenario, the estimated benefits to driver response time associated with the tested adaptive (swiveling HID) headlights ranged from 200 to 380ms compared with the fixed headlight systems tested. |
