Feeling Safe in the Dark : Examining the Effect of Entrapment, Lighting Levels, and Gender on Feelings of Safety and Lighting Policy Acceptability

This research examined to what extent physical factors, notably lighting and entrapment (blocked escape), and individual factors, notably gender, affect feelings of safety and the acceptability of reduced lighting levels. The authors reasoned that acceptability of reduced street lighting depends on perceived safety, which in turn depends on entrapment, lighting, and gender. Virtual representations of a residential street were used, systematically manipulating entrapment and lighting levels. As expected, people felt less safe in lower lighting and higher entrapment settings, and these settings were evaluated as less acceptable. Although women perceived a situation as less safe compared with men, the authors found no gender differences in acceptability, which extends previous research. Importantly, as hypothesized, perceived safety mediated the effect of lighting on acceptability levels, suggesting that people can accept lower lighting levels when social safety is not threatened

Obesity-related health impacts of active transport policies in Australia - a policy review and health impact modelling study

To review Australian policies on active transport, defined as walking and cycling for utilitarian purposes. To estimate the potential health impact of achieving four active transport policy scenarios.A policy review was undertaken, using key words to search government websites. Potential health benefits were quantified using a cohort simulation Markov model to estimate obesity and transport injury-related health effects of an increase in active transport. Health adjusted life years (HALYs) gained and healthcare cost savings from diseases averted were estimated. Budget thresholds to achieve cost-effectiveness were estimated for each scenario.There is broad recognition of the health-related benefits of active transport from all levels of Australian government. Modelling results suggest significant health-related benefits of achieving increased prevalence of active transport. Total HALYs saved assuming a one-year effect ranged from 565 (95%UI 173-985) to 12,105 (95%UI 4,970-19,707), with total healthcare costs averted ranging from $6.6M (95$1.9M-11.3M) to $141.2M (95$53.8M-227.8M).Effective interventions that improve rates of active transport may result in substantial healthcare-related cost savings through a decrease in conditions related to obesity. Implications for public health: Significant potential exists for effective and cost-effective interventions that result in more walking and cycling
