Vehicle Record
To calculate the total values for evaluations like Delay and Travel Time for
the network it is possible to collect data for all vehicles and filter it to get the
maximum values before the vehicle leaves the network. It is also necessary
to collect the values from the vehicles remaining in the network at the end
of the simulation.
There is one evaluation called Total Time that returns the total time the
vehicle spent in the network. This value is saved to file only at the last
second before the vehicle leaves the network. This is also the time step
that the delay time for that vehicle should be collected.
For the vehicles still in the network at the end of the simulation their total
time in the network must be calculated using their start times.
Results
The vehicle protocol file *.FZP consists of the following:
► 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)
► Brief description of output parameters
► Data block
The vehicle record file can contain any of the parameters listed below. The
table also includes the abbreviations that will be used within the vehicle
record file. Please note that some parameters will only report correct results
if the corresponding optional module (such as Dynamic Assignment,
Emission etc.) is installed.
Generally, current (short/long)distance/speed/acceleration units set via
VIEW - OPTIONS - [LANGUAGE &UNITS] are regarded for evaluation data output.
This does not apply to world co-ordinates which are always recorded in [m].
Please note: The units of those parameters with the particular unit
mentioned in the column header abbreviation will not change.
