current emphasis seems to be cars temporarily turning on street lamps as they pass or doing without – even re traffic lights – after a certain time to save money and also to reduce light pollution generally (astronomers press for this). Where parties have illuminations for pleasure authorities consider more green options and energy saving lamps. Failing to heat the streets as much may have a microenvironment backlash. During the air strike some years back now there are some nice smog free pictures of LA and facts have been extrapolated re the heat from lights, same as low level ozone levels re fumes from cars in summer and the need for trees to ameliorate chest problems. As usual, we are midpoint on progress but green issues are certainly worthy of consideration in all plans to give best possible answers on all designs and Times Square style flashiness is thought less appropriate even re parade days, etc.
