Hi. this is the first time i have posted a message to an email group so
forgive me if I make mistakes. I am a writer and have recently heard
about the possibility of mega traffic jams in the UK possibly caused by
a few freak combinations of events. this intrigued me and I thought (as
writers do!) of using this scenario as part of a novel. However before
I get carried away... i need to reseach this issue. Does anyone know
where I can find out more about the formation of traffic jams, what
might happen in a mega traffic jam etc?

BBC did that ages ago. Tube strike. Accident on M25 and roadwork's on
roads round M25 lead to massive jam on M25.
People dying in cars as it was winter. 100's of cars left on M25 as
police evacuated cars.
And a plane crash over Heathrow as air traffic controller was so tired
as the person who was suppose to take over from him was stuck in traffic
getting to Heathrow.
You should look into getting a copy of that. It was fiction. But was
based on fact and was done in a documentary type way.
