Vehicle automation and safe road infrastructure

The development of automated vehicles showed a rapid pace in the recent past, however less attention has been paid to the implications of vehicle automation on safe infrastructure design. This paper gives an introduction to a project addressing this gap. The project entitled "Physical and digital road infrastructure for Automated Vehicles" started recently and will last for five years (June 2019 – May 2024). Five initial workpackages have been formed. As a result of several brainstorming sessions these broad areas have been broken down into specific research tasks. A selection of the research proposals in this project are already in an initial phase or will be launched in the near future. Several MSc and PhD research topics were defined for present and future students.

Water resources engineering

In the water resource program, we are focused on three major areas for research: (1) water management and surface water hydrology, (2) unsaturated flow modelling with applications in transportation, geotechnical and ecological areas, and (3) karst flow modelling.

1. In the water management and surface water hydrology area, we are modeling un-gaged watersheds in Western-Hungary. Our efforts are directed at:

• Determining similarity parameters (hydrological, watershed, and meteorological) for measured watersheds, using the available database in western Hungary. Using yearly, monthly flows, and flow duration curves to determine index parameters.
• Applying different geostatistical methods (kriging, and topkriging) to estimate yearly and monthly flow in western Hungary.
• Modelling continuous rainfall-runoff processes by using daily measured data. Performing model selection, and sensitivity analyses with available software.
• Evaluating models through error analysis methods. Searching for relationships between error analyses methods, meteorological, and watershed characteristic changes.
• Using calibrated models to assess the impact of climate change in selected regions. Investigating the effect of climate change on the flow factor, minimum and maximum yields and annual distribution of water.
• Developing a decision-support system for water management problems in western Hungary.

2. Applying measurement methods to develop soil water characteristic curves and evaluating measured data. Assessing the impact of unsaturated water movement on various structures in civil projects (railways, dams) and on the stability of natural loess bluffs.

3. Describing karst spring flow using statistical methods. Determining the impact of climate change on spring flow. Correlating cave dripping to meteorological factors.
