1. 1. Modelling and Lagrangian control of mixed traffic: platoon coordination, congestion dissipation and state reconstruction

   Författare :Mladen Čičić; Karl Henrik Johansson; Miroslav Krstić; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; traffic control; Lagrangian control; mixed traffic models; Intelligent Transportation Systems; Connected and Automated Vehicles; traffic congestion; platoon coordination; moving bottlenecks; bottleneck decongestion; stop-and-go wave dissipation; traffic state reconstruction; Electrical Engineering; Elektro- och systemteknik;

   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.

3. 2. Gnutella Network Traffic : Measurements and Characteristics

   Författare :Dragos Ilie; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Gnutella; P2P; network traffic; measurements; statistical models;

   Sammanfattning : Wide availability of computing resources at the edge of the network has lead to the appearance of new services based on peer-to-peer architectures. In a peer-to-peer network nodes have the capability to act both as client and server. LÄS MER

4. 3. Computational interaction models for automated vehicles and cyclists

   Författare :Ali Mohammadi; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; automated vehicles; vulnerable road users; computational models; driver models; active safety systems; cyclists’ interaction;

   Sammanfattning : Cyclists’ safety is crucial for a sustainable transport system. Cyclists are considered vulnerable road users because they are not protected by a physical compartment around them. In recent years, passenger car occupants’ share of fatalities has been decreasing, but that of cyclists has actually increased. LÄS MER

5. 4. Background road traffic noise synthesis

   Författare :Georgios Zachos; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; background traffic noise synthesis; auralisation; urban sound planning;

   Sammanfattning : As urban planning evolves along with societal life, new requirements that should be met are rising. One of those, is the inclusion of acoustic quality in urban environments, before, during, or after a planning process. To address this for a yet to be built area, metrics are needed that try to quantify acoustic quality. LÄS MER

7. 5. Developing Microscopic Traffic Simulation Models for the Transition Towards Automated Driving

   Författare :Ivan Postigo; Clas Rydergren; Johan Olstam; Selpi Selpi; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Vehicles with different capabilities for automated driving will gradually be deployed in road transportation systems over the coming decades. Mixed traffic conditions may change the characteristics of the traffic flow dynamics. Microscopic traffic simulation is used for studying traffic flow dynamics in transportation systems. LÄS MER
