The computer simulation of road traffic is an important tool for control and
analysis of road traffic networks. Due to their requirements for computation
time (especially for large road traffic networks), many simulators of the
road traffic has been adapted for distributed computing environment where
combined power of multiple interconnected computers (nodes) is utilized. In
this case, the road traffic network is divided into required number of
sub-networks, whose simulation is then performed on particular nodes of the
distributed computer. The distributed computer can be a homogenous (with
nodes of the same computational power) or a heterogeneous cluster (with nodes
of various powers). In this paper, we present two methods for road traffic
network division for heterogeneous clusters. These methods consider the
different computational powers of the particular nodes determined using a
benchmark during the road traffic network division.
