  Braess' paradox has been shown to appear rather generically in many systems
of transport on networks. It is especially relevant for vehicular traffic where
it shows that in certain situations building a new road in an urban or highway
network can lead to increased average travel times for all users. Here we
address the question whether this changes if the drivers (agents) have access
to traffic information as available for modern traffic networks, i.e. through
navigation apps and or personal experiences in the past. We study the effect of
traffic information in the classical Braess network, but using a microscopic
model for the traffic dynamics, to find out if the paradox can really be
observed in such a scenario or if it only exists in some theoretically
available user optima that are never realized by drivers that base their route
choice decisions intelligently upon realistic traffic information. We address
this question for different splits of the two information types.
