\section{Abstract}
We are interested in the traffic of cars on a network, like for instance a city.
We describe traffic using hamilton-Jacobi equations,
and propose new general junction conditions that can be fully characterized.
In the framework of viscosity solutions for discontinuous hamiltonians,
we also prove a general comparison principle using a new vertex test function.
With this powerful tool in hands,  we show how to homogenize a general traffic on a whole network like a city.
