The main objective of the ISI-PADAS project was to improve the current design process of driver assistance systems, such as Partially autonomous driver assistance systems (PADAS), by effectively introducing a tool-supported risk based design methodology for the evaluation of hazards associated with human errors and inadequate driver behaviour. The basic goal of the improved methodology for Risk-based design (RBD) was to be able to create predictions of critical or error-prone situations for drivers, by a modelling and simulation approach.
Isi-PADAS aims to provide innovative methodology to support risk based design and approval of Partially Autonomous Driver Assistance System (PADAS) focusing on elimination and mitigation of dirver errors by an Integrated Driver-Vehicle-Environment modelling approach.
The main objective of the ISI-PADAS project was to provide an innovative methodology to support risk based design and approval of Partially Autonomous Driver Assistance Systems (PADAS) focusing on elimination and mitigation of driver errors by an integrated Driver-Vehicle-Environment modelling approach. The methodology contributed to:
- Halving the number of road fatalities by 2010 (respect to 2001 levels) and reducing number and severity of injuries caused by road accidents;
- And decreasing the level of human error.
Improvement of the current design process of driver assistance systems, such as Partially Autonomous Driver Assistance Systems ('PADAS'), was the objective of this project. To achieve that a tool-supported risk based design methodology has been introduced, to enable evaluation of hazards associated with human error and/or inadequate driver behaviour.
With Risk Based Design ('RBD') it is possible to create predictions of critical or error-prone situations for drivers, using modelling and simulation. Models for predicting correct and erroneous driver behaviour, based on modern approaches and algorithms, capable of capturing the key aspects of human behaviour, and retaining the fundamental characteristics of cognition and decision making or a simulation tool for predicting driver behaviour and driver errors to be integrated in a risk based approach are some of the developments needed. A huge amount of fully automatic simulations have been performed. These were based on models of the vehicle, the environment, the PADAS and the driver. For this purpose, ISI-PADAS developed a Joint Driver Vehicle Environment ('JDVE') Simulation Platform. Throughout the project the JDVE was used in different configurations: using human subjects or driver models, using PADAS or no assistance, and collecting data from real or simulated cars.
Several studies in different scenarios have been carried out, like: focussing on analysing driver behaviour without a PADAS, or investigating driver behaviour in interaction with different PADAS. Critical situations are most relevant for the risk assessment process but do not occur very often, even in the case of many simulation runs. To provide a better estimation of probabilities of critical but rare situations, an approach based on Extreme Value theory has been used.
Finally, the applicability of the Risk Based Design methodology has been successfully demonstrated on traffic light approaches as use-case scenario.
