  This article deals with the modeling for an individual car path through a
road network, where the dynamics is driven by a coupled system of ordinary and
partial differential equations. The network is characterized by bounded buffers
at junctions that allow for the interpretation of roundabouts or on-ramps while
the traffic dynamics is based on first-order macroscopic equations of
Lighthill-Whitham-Richards (LWR) type. Trajectories for single drivers are then
influenced by the surrounding traffic and can be tracked by appropriate
numerical algorithms. The computational experiments show how the modeling
framework can be used as navigation device.
