Dr.ir. H. (Haneen) Farah


Dr. ir. Haneen Farah is an Associate Professor in the Department of Transport and Planning and a co-director of the Traffic and Transportation Safety Lab. Her research interests lie in the fields of road infrastructure design, road user behaviour, and traffic safety. In her research she combines her expertise in transportation engineering, with her curiosity in the fields of human factors and econometrics. Before joining TU Delft she was a postdoctoral researcher at KTH - Royal Institute of Technology, Stockholm, Sweden. She received her M.Sc. and Ph.D. in Transportation Engineering from the Technion- Israel Institute of Technology.


The main aim of her research is to develop theories and models for road user behaviour and traffic safety taking into consideration the impacts of the road infrastructure and the technological developments and advancements in transportation. In her current research she investigates the implications of the advances in vehicle technology and automation on the road infrastructure design, road user behaviour and traffic safety in the framework of several national and international projects, such as: STAD (Spatial and Transport Impacts of Automated Driving), MEDIATOR (MEdiating between Driver and Intelligent Automated Transport systems on Our Roads), and SAMEN (Safe and Efficient OperAtion of AutoMated and Human DrivEN Vehicles in Mixed Traffic). 


In education she is responsible for the Geometric Design of Roads and Railways (CTB3370-18) undergraduate course and the Traffic Safety (CIE-5810-19) graduate course. She teaches as well in the online course Road Safety, and the  Delft Road Safety Course for low and middle income countries and gives lectures in the collaborative teaching program with the School of Traffic and Transportation, Beijing Jiaotong University. She supervises several PhD and Master students working on in her areas of research interests.

Taking the Fast Lane: Lane specific Motorway Traffic Control using GNSS Single Frequency Precise Point Positioning

This project aim to optimise lane use with a lane-specific control application. By evening out traffic over the available lanes, we can drastically reduce traffic jams. In addition to this, a more balanced traffic systems leads to increased safety and reduced emissions.

HFAuto Project: Human Factors of Automated Driving

HFAuto bridged the gap between engineers and psychologists through a multidisciplinary research and training programme. It generated knowledge on Human Factors of automated driving towards safer road transportation. Within this project we investigated the authority transitions between manual and automated driving. For this purpose, we collected empirical data from field operational tests and driving simulation experiments.

The project examined issues such as data availability and quality, as well as the relationship between data accuracy and calibration, as well as developing and testing methodologies suitable for calibration and validation of deterministic as well as stochastic models.

COOPERS -  Cooperative Systems for Intelligent Road Safety

COOPERS Vision provides vehicles and drivers with real time individual/local situation based, safety related traffic status and infrastructure status information distributed via dedicated Infrastructure to Vehicle Communication (I2V). This approach extends the concepts of vehicle autonomous systems and vehicle to vehicle communication (V2V) with tactical and strategic traffic information only be provided by the infrastructure operator in real time.
