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. Incident Traffic Flow Models
Sammanfattning : In the trend toward civilization, transportation has always been considered asan indisputable aspect. However, soon it turned out to be a dilemma in manymetropolitan areas how to assess the increased demand in transportation. The exigency for advanced alternative arises when constructing new roads and infrastructures lost its eligibility due to i. LÄS MER
3. 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
4. Future Train Traffic Control : Development and deployment of new principles and systems in train traffic control
Sammanfattning : The train traffic control system of the future requires new solutions and strategies in order to better meet tomorrow’s demands and goals. Uppsala University and Trafikverket have been collaborating for several years in research regarding train traffic control and how to improve traffic controllers’ support systems and working environment.

5. Control of vehicle platoons and traffic dynamics : catch-up coordination and congestion dissipation
Sammanfattning : Traffic congestion is a constantly growing problem, with a wide array ofnegative effects on the society, from wasted time and productivity to elevated air pollution and increased number of accidents. Classical traffic control methods have long been successfully employed to alleviate congestion, improving the traffic situation of many cities and highways. LÄS MER
