### Abstract

In this work we study the asymptotic traffic flow in Gromov hyperbolic graphs when the traffic decays exponentially with the distance. We prove that under general conditions, there exists a phase transition between local and global traffic. More specifically, assume that the traffic rate between two nodes u and v is given by R(u, v) ^{d(u, v)}, where d(u, v) is the distance between the nodes. Then there exists a constant _{c}, that depends on the geometry of the network, such that if 1 _{c} the traffic is global and there is a small set of highly congested nodes called the core. However, if _{c} then the traffic is essentially local and the core is empty which implies very small congestion.
