10. Enter External IDs for each detector, as illustrated:
- N41211A1
- N41211B1
- N41211C1
- J41211-2 (demand-dependent).
Microsimulation Configuration File
A file named microsim_config.cnf is required to serve as an interface between Aimsun Next objects and SCOOT objects. The file maps SCOOT junctions, detectors, and stage detector IDs to the corresponding objects in the Aimsun Next controller.
For this to work, it is essential that you have set the same external IDs for the junction and its detectors in both Aimsun Next and SCOOT, as explained in the previous steps.
To create the cnf file:
a. Open a new text document.
b. Rename the file cnf.
c. Add the SCOOT junction (J41211), detectors (N41211A1, N41211B1, N41211C1), and the stage detector (J41211-2) to the file.
d. Send this file to the SCOOT expert so they can process it and generate new IDs for these objects.
e. The expert will produce a new version of the file cnf, with the new IDs (201, 420, 625, 626, 627) alongside the previous junction and detector IDs.
f. Save the cnf file in this location:
C:\ProgramData\Siemens Mobility Limited\UTC\movable\sys\current\tcca.
The file format for junctions, stage detectors, and stage detectors is as follows:
-
- [Junction ID][space][ID][space]x
- [Stage Detector ID][space][ID][space]x
- [SCOOT Detector ID][space][ID][space]x
In our example, the contents of the microsim_config.cnf file will therefore be:
-
- J41211 201 x
- J41211-2 420 x
- N41211A1 625 x
- N41211B1 626 x
- N41211C1 627 x
11. Add a new controller to the Aimsun Next network and set the following parameters:
- Type: Siemens UTC System
- Tick Enabled
- External ID: 41211
- Intersection ID: 201
- Port: 2809
- IP: 127.0.0.1.
Port and IP values must match those in SCOOT. If in doubt, check with your SCOOT expert.
