Possibilities of simulation modeling of traffic accidents with reduced visibility
Rozsíval, Jan ; Motl, Jakub (referee) ; Bradáč, Albert (advisor)
The diploma thesis deals with the possibilities of simulation modeling with reduced visibility in the Virtual CRASH program, which as the only available programs allows work both with the help of mathematical models to simulate vehicle movement and change parameters to simulate reduced visibility, lighting, etc. The theoretical part contains a description of photometric quantities, deals with the human eye and its ability to see under reduced visibility, a description of the luxmeter meter and luminance analyzers. Here are four main reasons for reduced visibility and their description. It contains a sample of the most used programs used to deal with traffic accidents. The four types of headlights most commonly used in today's vehicles are listed and described. In the experimental part, two measurements were performed. The first measurement to obtain input values to obtain a black and white texture determining the shape of the light rays emanating from the vehicle headlights. The second experiment to obtain the contrasts of the white box, black box and pedestrian for subsequent comparison with the output of the Virtual CRASH program.
