A realistic description of the environment for inter-vehicle wave propagation modelling

Abstract

The modelling of a realistic environment for road traffic scenarios is presented. The model serves as a basis for a new wave propagation tool for inter-vehicle communications. A proper modelling of the environment implies an accurate characterisation of the dynamic road traffic and a realistic description of the vehicle's vicinity. For an accurate model of dynamic road traffic and realistic driving behaviour, different individual characteristics of vehicles are taken into account. Characteristics such as desired velocity or safety margin are determined stochastically within certain limits. It is therefore possible to create complex traffic scenarios without the need of having detailed and extensive traffic data for selected roads. Additionally, the road surrounding is generated stochastically, depending on morphographic data. The result is a proper traffic scenario, which serves as input data for wave propagation calculations.
