Transportation Systems Simulation - A Tutorial for Multi-Modal Simulation Using VISSIM/Freeway: Simulation

Before running a simulation, assure that each previous section has been implemented. The following section is the most basic method of extracting simulation data from VISSIM.


 * 1) Identify where the simulation data will be saved by selecting Evaluation  > Configuration from the top toolbar (see Figure below)
 * 2) Click  the “…” button and select the location/folder as your desired output directory
 * 3) Click OK
 * 4) Click OK

Set the “Simulation Parameters” by selecting Simulation > Parameters from the top toolbar (see Figure below)

Click OK

TIP: Higher “Simulation resolution” values will result in smother simulations while requiring more resources. Consider changing the seed to avoid similar results.




 * 1) Select the “Data Collection Measurement” tab below the Network Editor
 * 2) Click the “Autosave after simulation” button

TIP: To manually save simulation data, Click the “Save to file” button located left of the “Autosave” button


 * 1) On the top toolbar, Select Simulation > Continuous …sit back and watch the simulation run (see Figure below)
 * 2) *If VISSIM prompts the user to “Save changes?” Click Yes
 * 3) While the simulation is running, make a note of the following vehicular characteristics:
 * 4) *Vehicles are entering and exiting through the appropriate locations
 * 5) *HGV are generated by the simulation
 * 6) *Look for unusual behavior (stuck vehicles, merging issues, disappearing vehicles, unused lanes, connector issues …)
 * 7) Watch the entire simulation carefully, zoom in and out to locate trouble areas
 * 8) Let the entire simulation finish to automatically save the results
 * 9) Values will being to generate in the “Data Collection Measurement” window as the simulation runs
