Traffics

Hybrids are probably better for traffic then my car.

Hybrids are probably better for traffic then my car.

A sudden revelation came to me while sitting morosely in traffic: traffics are compression waves!

This thought made me want to simulate traffic in a 1D or maybe 2D particle model. The cars on the road have a given linear density of car and so the rate at which braking is propagated back is much higher then the individual car velocity.

The best time to see the traffic compression waves is approaching an uphill slope at night, then the brake lights can travel down the line of traffic eventually to your own car.

Maybe some more time stuck in traffic at night will help flesh out the model of traffic waves.
