1. Modelling and Lagrangian control of mixed traffic: platoon coordination, congestion dissipation and state reconstruction
Sammanfattning : Traffic congestion is a constantly growing problem, with a wide array of negative effects on the society, from wasted time and productivity to elevated air pollution and reduction of safety. The introduction of connected, autonomous vehicles enables a new, Lagrangian paradigm for sensing andcontrolling the traffic, by directly using connected vehicles inside the traffic flow, as opposed to the classical, Eulerian paradigm, which relies on stationary equipment on the road.

2. Distributed control of interconnected systems and its application in traffic control
Sammanfattning : Over the past few decades, the need for mobility and road transportation has been significantly increased over the world. This turned as a dilemma in many metropolitan areas as traffic congestion costs energy and takes time of all individuals who live in big cities. LÄS MER
3. Modelling of Substance Flows in Urban Drainage Systems
Sammanfattning : Stormwater is recognised as a large contributor of toxic substances to receiving waters. Different measures to manage stormwater quality have been proposed, including structural and non-structural best management practices (BMPs). Computer models have become useful tools for the analysis, evaluation and design of these BMPs. LÄS MER
4. Modelling of Traffic Performance for Swedish Roads and Motorways
Sammanfattning : This thesis consists of five scientific articles oriented towards capacity. Managing capacity constraints with associated delays is a big issue at new design as well as at trimming existing traffic facilities. LÄS MER
5. Born in fire, borne by air : Source attribution and physicochemical characterization of ship and ambient aerosols in the Baltic region
Sammanfattning : Aerosol emissions from anthropogenic activities cause detrimental health effects and affect the climate system. Combustion is a large source of airborne fine particulate matter (PM2.5) and the uncertainties of the climate role of these emissions are still large. LÄS MER
