The Institute for Roadside Aachen has been acknowledged and recognized as an independent research institution for decades, both in basic research and application-oriented research. By diversifying the research spectrum, we are able to continuously expand our core competencies and pass on the know-how to our customers.

Construction Technology

In addition to the conceptual design of application-optimized asphaltene as well as the analysis in the context of extended bitumen tests, the research activities of the Institute of Highway Engineering in Aachen focus on all aspects of the characterization and evaluation of road surfaces.
The institute has built up competencies, especially in the fields of longitude and grip. Various methods have been developed and tested extensively and transversely for the purpose of assessing their durability.
The investigation of the processes occurring in the tire-road contact forms an important basis for the achievement of the defined goal of replacing the grip measurement methods currently in use with a non-contact measuring system in the foreseeable future.
Recent research efforts are focused on the development of the "Intelligent Road", or more precisely, a complex road sensor that provides the road user with all relevant information for safe and efficient use of the road network at any time and place.


Road planning, road operation and road traffic engineering

  Road Planning isac

The Institute of Highway Engineering deals with central topics of road planning and road design.
The topics of the road planning and road design work are all questions concerning the proper design of roads as well as the analysis of design bases and design principles in the directives with regard to their impact on traffic safety as well as on work safety.

The most important areas of activity and research at the Aachen Institute for Roads are:

Traffic data collection and analysis

  • Collection of traffic data for the description and analysis of the traffic flow
  • Use of micro simulation, eg for comparison of planning variants

Traffic control and safety

  • Traffic control systems, as well as their control and effectiveness
  • Traffic quality of individual plants and related stretches
  • Individual and collective traffic control
  • Traffic safety and development of future-oriented predictive procedures

Management of workplaces

  • Security and management procedures
  • Road equipment, for example innovative signs, markings and protective devices

Tunnel equipment and operation

  Tunnel equipment and operation isac

The Chair and Institute of Highway Engineering has its research areas for underground transport facilities in the equipment, operation and control of road tunnels.
Safety aspects and environmental issues play a crucial role in this context.
In addition, the Institute of Highway Engineering deals with questions of ventilation, video detection, fault management as well as the planning and design of tunnels.
