VISSIM 5.30-05 User Manual

13 VISSIM Programming Interfaces (API)
13.7 Tolling – TollPricing.DLL
In VISSIM, user defined Toll Pricing Calculation Models can be implemented
as COM scripts or specific *.DLL files.
Such a file *.DLL can be selected in the TollPricing Calculation Models dialog
if the option COM-Script is activated, cf. section 5.6.2.
The *.DLL must contain the functions declared in TOLLPRICING.H: Init() and
Exit() are called from VISSIM at the start respectively end of a simulation run
and can be used to initialize the *.DLL respectively clean up. CalculateToll()
is called whenever a new toll price needs to be calculated, i.e. at the start of
each calculation interval of each managed lane facility, once per user class
(SOV, HOV2, HOV3+).
VISSIM passes the number of the managed lane facility, the user class, the
current simulation time, the travel time savings (in minutes) on the managed
lane and the average speed on the managed lane (both since the start of the
last interval) and it expects the new toll price to be stored with the reference
variable .
