Occasionally projects will require extensive pre-or post-processing or numerous scenarios to be investigated. For these cases VISSiM can be run from within other applications serving as a toolbox for transportation planning algorithms. Access to model data and simulations is provided through a COM interface, which allows VIsSIM to work as an Automation Server and to export the objects, methods and properties described in this document. The VIsSIM COM interface supports Microsoft Automation, so you can use any of the RAd(Rapid Application Development tools ranging from scripting languages like Visual Basic Scrip or Java script to programming environments like visual C++ or Visual J++ The examples presented in this manual are mainly in visual Basic, see page 199 for a little introduction. You will also find a short introduction on how to use it with Visual C++ on page 209 An introductory Visual Basic example will illustrate the flexibility of this approach. Assume that we want to run several simulations with different random seeds and get their respective link evaluations. You can use Excel and VBa (Visual Basic for Applications) to load the network, set the different random seeds and start the process. For example, if you want to use the network fixed time. inp"and to run four simulations with the random seeds 10, 20, 30 and 42 you can edit the following Excel sheet random seed simulation fille 10 G: \PTVDATAIFIXED TIMEINP 30 42 You can also insert a button "START(from the toolbox)to link with the Visual Basic code presented Start at the end of this section To get the link evaluations by running the Excel macro you have to create a SAK file within the same directory beforehand. You may use the VISSIM Link Evaluation Dialog(or the LinkEvaluation interface)for this purpose VISSIM.30-00 PTVAG 2007 9 1 Introduction B Link Evaluation Configuration Layout of column Parameter select 1: Simulation time Density amber Emissions〔 evaporation)H En uhti:99999 Emissions ntery Emission念NMH Emission s mmog Emissions particulates Emissions sa2 Fuel Consumption ehicle clas AI vehicle Type 回 Per Lane D VISUM Export(network link attributes) □ⅥsuM9 Format〔 else suM8 Format □ Datab示8 Table name: VISSIM LINK EV OK[Cancel It is also necessary to check the box for the link evaluations in the Evaluations> Files Dialog and to save the options in a *.
