Resumo(s)
Road accidents are a constant reality these days, therefore to reduce and understand these
accidents and, as a result, improve road safety, an analysis will be carried out on modern and
old accident reconstruction methods and how they can be improved.
With the new 2022 European Union regulation coming in, which enforces the use of Event
Data Recorders (EDR) on newly made vehicles, suddenly there’s a system that can record
vehicle dynamic data and driver inputs, in case of an accident. This project’s objective is to
analyze this data in an accident context and simplify the reconstruction process.
This project aims for a seamless interpretation of the accident scene and vehicle dynamics to
better understand the data in the scene’s context. Some methodologies and tools used for the
reconstruction of the accident scene will be studied, culminating in a system that digitizes the
scene for later use in computer software.
The dynamic data from the accident can be divided into three phases: pre-crash, impact,
and post-crash. Each phase requires a different approach which depends on the type of data to
obtain the trajectory of the vehicle throughout the phases.
