In addition to the equipment in the area of Road Construction Technology, various measuring systems for the detection of traffic-related and planning issues are available for the Institute of Highway Engineering.
Both check tests for traffic detection systems and complex traffic correlations for entire streets or road networks can be detected.
For the measurement of local parameters, speeds and traffic compositions, for instance side and bridge radar systems are used which can be extended by video detection and evaluation units, isac-DVA in short. The optimal positioning of the video units is ensured amongst others by an 18m video mast. The determination of route-related parameters can be captured in detail by the use of correlation-optical sensors ,Corrsys-Datron, (for example for acceleration or deceleration operations) or via GPS-receivers for the determination of route speeds or driving times.
The institute also runs a driving simulator laboratory, isac-FaSi in short. Due to the almost 360° projection in a complete vehicle (e.Go) and the sound simulation, the driving simulator enables an exact replication of road conditions and driving manoeuvres, so that a variety of scenarios can be tested without risk. The driving simulator can be used to carry out various studies, including perceived road safety (Risk Assessments), the effect of innovative information and warning systems (AdaptIn) and driving behaviour in complex junctions (NeMo).
With the help of real video data or routing software in combination with visualisation software, any route can be displayed and virtually driven through. The 180° view to the front is simulated via three image channels. The high-performance beamers (1920 x 1200 pixels each) project onto a dome with a radius of 5.8m. For the visual display in the two exterior mirrors and the rear-view mirror of the mock-up, a screen is available behind the vehicle. For each mirror, a section of the image is projected onto the screen (1920 x 1080 Full HD and 5,500 lumens). In addition, there are two freely programmable displays in the vehicle.
The 3D environment is rendered with the help of the Unity 3D engine, which makes it possible to simulate any scenarios.
Furthermore, it is possible to use eye-tracking glasses to gain a more precise insight into the specific behaviour of the test persons.
