  The research project HDV-Mess aims at a currently missing, but very crucial
component for addressing important challenges in the field of connected and
automated driving on public roads. The goal is to record traffic events at
various relevant locations with high accuracy and to collect real traffic data
as a basis for the development and validation of current and future sensor
technologies as well as automated driving functions. For this purpose, it is
necessary to develop a concept for a mobile modular system of measuring
stations for highly accurate traffic data acquisition, which enables a
temporary installation of a sensor and communication infrastructure at
different locations. Within this paper, we first discuss the project goals
before we present our traffic detection concept using mobile modular
intelligent transport systems stations (ITS-Ss). We then explain the approaches
for data processing of sensor raw data to refined trajectories, data
communication, and data validation.
