1 Introduction VISSIM can be applied as a powerful tool in analysis of a huge variety of transportation problems. 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 Script 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 file G:\PTV\DATA\FIXED_TIME.INP 10 20 30 42 You can also insert a button “START” (from the toolbox) to link with the Visual Basic code presented 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: Start VISSIM 4.30-00 © PTV AG 2007 9
