D48 for the curious people !
Pollution day in europe, first days of Spring, when everybody is packing up along the roads to the same hiking areas, perfect day to talk about the science behind traffic jams !
Did you know that traffic jams and queueing had their own science and studies ?
Since 1993, researchers have studied and published results about what could cause and suppress traffic jams :
- Traffic controls
- New break techniques
- speed limits
- Traffic controls
- New break techniques
- speed limits
Often, the same conclusion was reached : everything that allows for a more constant speed on the road allows for less traffic jams. On the contrary, (abrupt) changes of speed create traffic jams, but often behind the "responsible" car, which will not even know about the traffic jam it just created !
A summary of 20 years of traffic jam research ? Follow this link !
![[Four figures in time sequence: the wreck is cleared,
and a 'wave' of spaces moves backwards as cars begin
to leave, yet more cars stack up behind. A 'wave' of
stopped cars moves backwards along the highway.
The cars are unmoving, yet the wave itself moves.]](https://lh3.googleusercontent.com/blogger_img_proxy/AEn0k_tNfWuCLTqAepQEtoOCYxOBeOnjaXCtBYg_VP7rm1v_UcJME0jAlYpbcwnqoq6EttBgWuO6pAf7NoBz3tmZ2s2AjBfD=s0-d)
