  Personal Rapid Transit (PRT) is a promising form of urban transport. Its
operation consists in the use of small unmanned vehicles which convey the
passengers among stations within a dedicated network. Various aspects of the
PRT network performance are frequently evaluated using the discrete-event
simulation. The paper supports the need of establishing some reference models
for the simulation of PRT networks, targeted mainly towards the needs of the
research on network management algorithms. Three models of such PRT network
models are proposed and discussed. The presented models can play the role of
benchmarks which would be very useful for comparative evaluation of heuristic
control algorithms, developed by different research groups.
