    Promoting real Life Observations for Gaining Understanding of road user behaviour in Europe

Technical issues

This task aims at an inventory of the current data collection and data analysis equipment and techniques for naturalistic observation studies as well as the theoretical analysis of requirements for different application areas.

The main input comes from previous and on-going studies that applied a fleet of instrumented vehicles to collect data on both driver and vehicle behaviour together with collecting data from the outside world (road and other road users) by different types of sensors, as the main purpose of naturalistic observation studies is to gain a better understanding how driver, vehicle, and road and traffic factors interact with each other.

Reliable and consistent methods for managing huge amounts of data including data quality and completeness checks and requirements get special attention. The review also includes an inventory of which influencing factors and conditions (for example, status of vehicle, type of road, weather conditions, road conditions, traffic conditions, driver status) should be known and which metrics (both longitudinal and lateral) are necessary to collect data for and which sensors are required or obtaining the data for the different application areas. Probably, a distinction has to be made between absolutely necessary measures (minimum variant) applicable for a large amount of vehicles and more detailed set of measures for a limited set of vehicles.
