Intelligent Intersection: Finalization of the Project IntIntSec

(comments: 0)

For some time now, we have been working on the development of the "intelligent intersection" as part of the IntIntSec project. On Friday, February 2nd, the project partners TU Wien, Austrian Traffic Safety Board (KfV), swarco, komobile and ANDATA met for project completion and exchange together with invited partners and interested parties.

The aim of the project was to determine what contributions can be made by the comprehensive interconnections of road users with each other and with the infrastructure through C-ITS services (V2X communication, ITS-G5) and available or promised 5G services for an "intelligent intersection".

The results of the project include:

  • New performance parameters (KPIs) for control strategies: the control strategies of individual vehicles for the intersection passage as well as the traffic control can be uniformly evaluated for any traffic situation with respect to
    • traffic capacity, reserves, congestion risks, traffic efficiency
    • safety and collision risks
    • comfort, lost times, traffic flow quality, complexity of traffic situations
    • energy demand, emissions
  • Optimal control strategies: depending on the respective traffic situations, the optimal strategy for achieving the above goals (KPIs) is automatically determined, whereby the goals can be weighted depending on the traffic situation.
  • Extended control actions: in addition to the traffic light phases and green times of a conventional control system, other actions such as C-ITS services and individual recommendations and warnings for all road users can be integrated.
  • Digital Twin: the intersection is replicated in a digital twin. This includes a precise and uniform picture of the traffic situation, which is used to determine the optimal control strategy. The digital twin also includes C-ITS services such as Collective Perception and others. The digital twin also forms the technical basis for a functionally safe and trustworthy design of the information exchange of all road users with the infrastructure.
  • Scenario Management: the intersection is connected to a complete, (partially) automated scenario management system.
  • Identification and prediction of traffic situations: traffic situations can be precisely identified and predicted with suitable C-ITS services by integrating and using the interconnection of the road users.

This provides and describes all the necessary components to make a traffic intersection "intelligent" and adaptive for the best possible design of safety, efficiency, comfort, energy and emissions by connecting road users with each other and with the infrastructure.

The solutions are available as part of VERONET, ANDATA's traffic automation stack.
