Some time ago this point was already raised on Kings Cross Local noting that black-cabs with running engines queued as far as Goods Way.
I would like to know if it is possible to manage advance of cabs better than meter by meter which require engines to be kept running. Here is a suggestion: If progress to the pick-up points would be in threes or fours, that is a cab advances every time three or four vehicles in front have moved, rather than the bumper to bumper advances we observe at the moment, it would allow the switching off of engines, and as a result a slight lowering of emissions. A little bit of paint on the roads creating painted queuing boxes for three or four cabs behind each other alongside the full queuing stretch either up to the German Gymnasium or up to Goods Way and a few signs explaining the system is all that would be needed. Only in the last box where passengers are picked up running engines should be allowed.
Here is an illustration:
Goods Way/1234/1234/…../ 1234/1234/1234 /pick up point / Euston Road
During the air quality summit at Camden Town Hall last year it was highlighted that the emissions from black cabs constitute a high percentage of the overall traffic emissions. Whilst changes on engine technology here are one issue, a little bit of management of the queuing system can achieve a lowering of emissions at Kings Cross / St Pancras at ease.
On the topic of idling engines London mayor Boris Johnson announced last year that he would introduce fines for keeping engines running (see Evening Standard here).
