  Title Intelligent dynamic road lighting and perceived personal safety of pedestrians Type Journal Article
  Year 2010 Publication Eindhoven University of Technology Masters Thesis. Abbreviated Journal  
  Volume Issue Pages (up)  
  Keywords Perception  
  Abstract The function of road lighting is to prevent crime, provide a sense of perceived

personal safety, as well as the ability to successfully orientate and navigate urban

environments at night. However more and more people realize the negative effects of

abundant street lighting, such as light pollution and energy consumption. In 2001, 63 per cent

of the world population was confronted with night skies brighter than the threshold set for

light pollution by the International Astronomical Union (Chepesiuk, 2009). Exposure to light

pollution over longer periods of time can have lasting negative effects on the health of both

human and wildlife. A second motive for reducing abundant road lighting is sustainable

energy usage. The total energy consumption of public lighting in the Netherlands is currently

estimated to be 600.000 to 700.000 MWh a year, of which about 500.000 MWh is used for

the lighting of infrastructure such as roads, bicycle trials and footpaths (SenterNovem, 2009).

Reducing energy consumption and light pollution by road lighting can be realized using

intelligent dynamic road lighting systems with LED technology. Such intelligent dynamic

road lighting systems can offer light only when and where it is most needed, thereby

preventing light pollution and energy waste. However, such dynamic lighting should not

negatively affect a pedestrian’s perceived personal safety, because fear of crime often elicits a

stress reaction, to avoid, to reduce, or to cope with a threatening situation (Riger, 1985).

Therefore the addressed research question in this report is “What is the influence of different

dynamic road lighting scenarios on perceived personal safety” In particular, where would

pedestrian’s benefit from light the most e.g. at their own location or in their direct

surroundings?

To answer this research question a field study is performed using testbed “de Zaale”

on the campus of the Eindhoven University of Technology. “De Zaale” is normal street

setting equipped with intelligent dynamic road lighting containing twelve lampposts over a

range of 350 metres. A three condition (three different light distributions: darkspot, spotlight,

and a control condition) within-subject experiment was conducted with perceived personal

safety as the dependent variable. These three light scenarios are designed to have opposing

light distributions at the location of the pedestrian, with an equally amount of illumination.

To explain differences measured in perceived personal safety Appleton’s prospect and refuge

theory is used complemented with a social psychological model by van der Wurff and

colleagues (van der Wurff, Staalduinen & Stringer, 1989; Appleton, 1975). The dependant

variable perceived personal safety and the independent variables prospect, concealment,

exposure, escape, attractiveness and power are measured using an equidistant 5-point

answering scale questionnaire.

Considering the results the present study demonstrates that the manner in which light

is distributed across the poles in an intelligent dynamic road lighting setup influences the

perceived personal safety of pedestrians at night. We have shown in an experimental field

study that light has an effect on the proximal cues prospect, exposure, concealment and

escape. Prospect is indicated to be the most important proximal cue influencing a pedestrians

perceived personal safety. The relatively highest level of perceived personal safety is

experienced when a pedestrian’s personal and action space are sufficiently illuminated.

Illuminating these areas increases prospect, exposure an escape, and decreases concealment.

Additional illumination in a pedestrian’s vista space does not necessarily contribute to the

increase of their perceived personal safety. Furthermore individual differences between

pedestrians such as gender and attractiveness can enhance the negative effect of poorillumination on perceived personal safety. This knowledge should be integrated in the future

design of an intelligent dynamic road lighting system in order to maximise the personal safety

of pedestrians using such a system at night.

  Title Investigating whether a crime reduction measure works Type Journal Article
  Year 2006 Publication Radical Statistics Abbreviated Journal  
  Volume 91 Issue Pages (up)  
  Keywords Public Safety  
  Abstract Crime is a serious business. It causes great distress and fear. It costs a lot

to deal with its consequences. In these regards crime shares much with

the problem of ill-health and disease. The application of sound science and

statistics has allowed great strides to be made in dealing with problems of

ill health. Medical statistics is one of the recognised, established

disciplines involved in researching healthcare.

The parallels between research in crime reduction and in healthcare do

appear to differ in terms of quality. Although there is still room for

considerable improvement in researching health-care, an investigation

into the underpinning of statistical methods used indicates that the

problems are substantially worse in the study of crime. The consideration

given to statistics in crime studies seems rather flimsy, yet important

claims are made which are statistical at source and may affect policy, and

so can have considerable costs attached. Therefore, for example, it is

important to know whether the underlying crime level has really changed,

rather than just being the result of perhaps sampling variation or some

artefact giving rise to statistical bias or systematic error. This is necessary

when trying to determine whether a Crime Reduction Intervention (CRI)

has actually worked.

I started examining the scientific basis of the claim for the effectiveness for

one particular CRI, basically because I was concerned about negative side

effects and I thought the claim implausible. I remain concerned and

unconvinced. The statistical issues and concerns I raise apply also to

investigating other CRIs and to existing published analyses.

This piece extends work presented in Marchant (2006); earlier work on the

statistical issues involved can be found in Marchant (2005a, b; 2004).

  Title The Chicago Alley Lighting Project: Final Evaluation Report Type Journal Article
  Year 2000 Publication Illinois Criminal Justice Information Authority Abbreviated Journal  
  Volume Issue Pages (up)  
  Keywords Public Safety  
  Abstract Begun in October of 1998, the first part of the plan sought to upgrade and improve the city's 175,000 streetlights, which illuminate the arterial and residential streets. The second part of the plan involved repairing and upgrading the lighting in and around viaducts and Chicago Transit Authority stations. The final part of the plan has been to boost lighting levels in alleys across the city as a tool for public safety and fighting crime. In the past, 90-watt lights illuminated most city alleys; alley lighting levels have been increased by installing new fixtures that can accommodate 250-watt bulbs. The Illinois Criminal Justice Information Authority undertook an evaluation to assess the impact of increased alley lighting on crime rates in two eight-square-block areas, with emphasis on crimes that were most likely to have occurred in alleys. The evaluation first examined change in the experimental area that received increased alley lighting over a 1-year period prior to increased alley lighting and a 1-year period thereafter. Next, change over a 6-month period before and after increased alley lighting was examined for both the experimental area and the control area. The evaluation found that reported offenses increased between the 1-year preinstallation and 1-year postinstallation study period in the experimental area where alley lighting was improved. The evaluation also found that the experimental area experienced more notable increases in reported incidents over a 6-month preinstallation and 6-month postinstallation study period compared to the control area. The evaluation could not provide a definitive explanation of these findings.
