To an extent, Dr Jemima Unwin and Professor Peter Raynham's article in this edition, from page six, on the relationships between street lighting and safety at night doesn't get us much further along in what is a complex and difficult debate. It is clear in its conclusions: that trying to generate precise formulas for lighting for safety and perceived safety is probably 'futile', given how context-dependent good lighting design will be; that following lighting guides and standards 'is a safe bet' but may not in itself create a design or scheme that lends itself to feelings of safety at night; that it is always sensible to be thinking in terms of how a scheme provides light that facilitates movement, orientation, comfort and reassurance. But it also emphasises that these are just 'pointers' for further debate, discussion and research.
