Project TUSIMA

Tunnel simulation und human factor analysis

TUSIMA is a research project in cooperation with the InterOffice GmbH within the scope of PRO-INNO sponsoring program.

Project Goals

The objective of the Project was the development of a generic tunnel Simulator, which could help to derive insights about a tunnels safety potential while taking into consideration the risk factor “traffic participants”.

The simulator was supposed to excel in its flexibility and ability to be adapted easily to existing or planned tunnel constructions. Another requirement was the option to implement variants of the geometry or equipment, or even the lighting conditions; those changes should be testable regarding their effect on potential traffic participants and their stress level. In order to do that, human behavior was simulated using a man model which was based on a multitude of studies with cross-sectionally chosen test persons.  This model included information about the behavior and stress development of those probands in a broad range of tunnel configurations.

Results

The results of project TUSIMA act as a new,  groundbreaking development in the field of real-time tunnel geometry and human emotion simulation. The simulator that was created as part of the project is unique in its special focus on the safety factor man; it opens up completely new options for safety optimized tunnel planning.  One of the most important factors was the realistic simulation of all variables that have an effect on the driver passing through the tunnel, including the changes they cause in the driving behavior.

In summary, the results of the project include:

Tunnel Simulator

• Modular 3D geometry modeling ( Tunnel Configurator)
• Emulation of different lighting scenarios
• Emulation of different equipment configurations
• Emulation of consequences of an accident
• Creation of traffic situations

Man Model

• Modeling of the steering behavior and speed control as a function of tunnel geometry, illumination and tunnel equipment
• Modeling of internal stress level
• Simulation of different driver types ( aggressive, experienced, anxious )
