Saving SSAM trajectories to a file
You can save a binary file *.trj that contains trajectories. Trajectories describe the course of vehicle positions through the network. This includes the z coordinates of a vehicle. You can upload the file *.trj to the Surrogate Safety Assessment Model (SSAM) of the Federal Highway Administration Research and Technology of the U.S. Department of Transportation. SSAM is used to evaluate the road safety of transport routes. The content of a binary file *.trj cannot be interpreted in a text editor.
You can limit the scope of the data entered to those parts of the Vissim network, that are relevant for your evaluation (to individual nodes, for example). These parts of the Vissim network must be located in sections by which Vissim filters the data. You can select the desired sections.
You can save the following data and data formats:
|

1. From the Evaluation menu, choose > Configuration > Direct Output tab.
2. In the SSAM row, select the option Write to file.
3. If you want to filter by sections, click the More... button.
The SSAM window opens.
4. Hold the Ctrl key down and select the sections for data filtering.
5. Confirm with OK.
6. Start the simulation (Running a simulation).
A file *.trj is saved.
