IntIntSec - Intelligent InterSection

The project aims at developing novel, integrated and flexible communication, control and simulation methods to implement the "intelligent intersection" system.

Short Description

Increasing volumes of traffic in inner-city areas aggravates the tensions between safety, traffic efficiency and environmental pollution. While intersections are critical nodes in traffic networks, most of them are simplified and only controlled via fixed, pre-defined traffic light phase schedules.

Inflexible, sub-optimal traffic light control can lead to unnecessary traffic jams and vehicle emissions. The individual needs, requirements, and possibilities for different road users (e.g., connected vehicles, pedestrians, cyclists, scooters, etc.) are not properly considered.

Modern ICT, communication and control concepts offer the potential to comprehensively manage intersection traffic in real time, to consider the requirements of all road users, interpret the situations accurately, and to implement individual, coordinated and cooperative control strategies to achieve a holistic optimum.

The project will collect, link and use available real-time information of the positions, speeds and expected behavior of many different road users in order to simultaneously

  1. ensure traffic safety for all road users,
  2. regulate the resulting traffic flows efficiently, and thus
  3. minimize the overall energy consumption and emissions of the road users due to the intersection passage.

The involvement of the many, heterogeneous relevant stakeholders in terms of human-centered design, the effective technical design and solution of the required optimization, control, and communication approaches, and the evaluation of these solutions go far beyond the state of the art and require the R&D work within this project.

Context information (time of day, weather, regional traffic volume) is combined with real-time data provided by on-board sensors (e.g., from connected vehicles with assistance systems) or innovative traffic monitoring systems (e.g., for pedestrians or cyclists).

This comprehensive approach makes it possible to capture the intersection situation in more detail, control traffic more efficiently and resolve dangerous situations or even prevent them from occurring in the first place.

To this end, the project also aims to develop new communication methods to enable interaction with the different road users. IntIntSec will not only provide design methods for intelligent intersections but will also quantify the added value for the various groups of road users (including pedestrians), residents, operators, public actors and traffic planners, and develop an interdisciplinary, inclusive methodology for obtaining these findings.
