VISSIM 5.30-05 User Manual

● Queue Definition
defines the queue
condition: A vehicle is
in queue condition if
its speed
- is less than the
Begin speed and
- has not exceeded
the End speed
yet.
Queue Counters and Vehicle Stops
- Max. Headway defines the maximum distance between two vehicles
so that the queue is not disrupted.
- Max. Length defines the max. length of the queue - even if the actual
queue is longer. This parameter is helpful if longer queues are
detected in a network of subsequent junctions but the queues are to
be evaluated for each junction separately.
● Time: The starting and finishing time and the time Interval of the
evaluation (defined as simulation seconds). Definition of the aggregation
interval (in s): If value 600 is entered, the *.STZ file will contain data
blocks of 600s each, starting from the value entered for from.
● Analyzer Sample Interval: Enter the number of simulation seconds (e.g. 0
or 10) for evaluations via Analyzer Report, cf. section 11.24.
● Database: When active, evaluation output is directed to a database to
the specified Table Name (rather than to an ASCII text file). The table
name must not be used for any other VISSIM database evaluations. In
order to use the database output the database connection needs to be
configured (see section 10.1.3).
The simulation performance depends on the value set for Max. Length. If
there is a big queue building up in the network, and the Max. Length parameter
is set to a greater value (e.g. 4 km), the simulation speed will decrease.
Results
This is the format of an output text file (*.STZ):
► File title
► Path and name of the input file (File)
► Simulation comment (Comment)
► Date and time of the evaluation (Date)
► Version no. with Service pack no. and Build no. (VISSIM)
► List of all queue counters that have been evaluated
