Ever wondered why you spend so much time stationary on the motorway?

That is excellent.
I've been playing with the lane closing option. Leaving all other parameters alone, I found that queuing started when the main inflow was increased to around 1770 vehicles per hour.
While I knew it would have to drop quite a bit for the queuing to clear, what has surprised me is just how low you have to go - I haven't found it yet!

Watching the default simulation it was all down to one truck pulling out very slowly and then it just gets worse until the incoming traffic flow on the motorway almost stops then it starts to recover - even dropping the ramp inflow to zero it still takes ages

Makes you realise why the variable speed limits you see on the M25 and other places which are designed to slow the traffic down as it gets heavier are so effective.

Wouldn't work for me! Seamonkey wanted a plugin and IE just displayed a grey box!

It needs Java to be installed.
