Road planning, road operation and road traffic engineering


The Institute of Highway Engineering deals with central topics of road planning and equipment, the traffic flow as well as road safety.


The topics of the road planning work are all questions concerning the influence of traffic, taking into account parameters of traffic safety and quality as well as the investigation of the effects of workplaces and their optimization on federal motorways.

A further research area is the investigation of the psychological perception and effect on the driver of spatial routing elements and cross-sectional types, as well as the road equipment. The institute is particularly suited to this area of research, using simulation techniques and a simulated driving simulator.

The area of transport and operation is concerned with organizational measures to improve traffic on roads. The most important areas of activity and research at the Institute of Highway Engineering in Aachen are:

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

Optimization of traffic control systems with regard to:

  • Effectiveness
  • Acceptance

Development of individual and collective traffic control

Development of forward-looking predictive procedures for road safety


Security and management procedures

Optimization of road equipment in the context of innovative signs, markings and protective devices


The Institute of Highway Engineering Aachen can look back on extensive experience in all of these areas. These includes both: the field of research and the field of application in practice.
