New Interface available

The new external interface for emulating the TRENDS kernel in VISSIM replaces the old „TRENDS429.exe“. The interface has the following new functionalities:

  • Simulation of TRENDS kernel 5.2, 5.1 and 5.0 as well as before the TRENDS kernel  4.2
  • Simulation of TRELAN-TL supplies (SIEMENS)
  • Perfomance optimization
  • Mark exchange with neighbouring intersections
  • Exchange of import- and export variables through a central (AP-Values)
  • Time dependent signal program switching
  • Simulation of PTV Balance and PTV Epics through TRENDS (needs an additional PTV VISSIM modul) as done in real implementations

The supply of the simulated traffic signal controllers is done analogue to the direct supply of the real traffic signal controllers with the traffic engineers workstation CROSSIG. From CROSSIG also interstages (*.pua) can be exported for the VISSIM module VISVAP. The linking is done via the VISSIM interface „External Signal Control “. It is available for VISSIM 5, 6, 7 and 8.
