Generally, Advanced Parking Management Systems (APMS) use Variable
Message Signs (VMS) to provide drivers with updated information on the number of
open spaces at selected off-street parking facility to minimize or avoid parking search
traffic within a full car park facility, and reduce the delay times at the entrance and exit
gates of a parking facility. The simulation model STARSIM-VMS is developed, in the
present study, to simulate the operation of a designed parking garage with the
implementation of the VMS technology. The simulation results show that the delay
values is smallest than that predicted without using the VMS technique, especially at
the high proportions of vehicles waiting to park. These results reflect the importance of
using the VMS in the transportation systems.
