VISSIM 5.30-05 User Manual

Runtime Messages
For some errors, a message box also
appears prior to the start of the
simulation.
Without option Do not show this
message, any subsequent error
messages will be shown. If this option
is active, all subsequent messages of
the same kind will be suppressed.
But still all errors will be logged to the
error file.
These are some of the problems/errors that VISSIM reports:
► A routing decision that is placed too close to the start of a connector.
► A desired speed decision that might be placed too close to the start of a
connector. This message does not necessarily point to a problem as a
simplified method of computing the minimum distance is used.
► An entry link that did not generate all vehicles as defined by the coded
input flow because of capacity problems resulting in a queue outside the
network at the end of the defined time interval.
► A vehicle that has been removed from the network because it had
reached the maximum lane change waiting time (default = 60 seconds).
► A distance too short between the beginning of a routing decision and the
first connector causing a vehicle to leave its route because it has not
enough time to stop beforehand.
► The passage of more than 5 connectors at the same time by a single
vehicle resulting in a virtual shortening of the vehicle in the visualization.
► For signal controllers that use information on intergreen and minimum
green times: Each violation of one of the times defined in VISSIM will be
reported if it occurs during a simulation run.
► Pedestrians add-on: On pedestrian areas, the number of pedestrians per
simulation second exceeds the limit.
