1. 1. Foliated Transportation Networks - Evaluating feasibility and potential

   Författare :Joakim Kalantari; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hybrid transportation systems; transportation network modeling; intelligent transportation systems.; transportation planning and control; transportation network simulation; transportation network optimization; Transportation networks; transportation network performance; mixed model transportation; transportation network efficiency;

   Sammanfattning : Neither the critical role that transportation plays for economic activities nor its negative external effects can be denied. At the same time, the resources required to sustain and develop the transportation system to an adequate degree and at the required pace are limited. LÄS MER

3. 2. Foliated Transportation Networks - Exploring feasibility and potential

   Författare :Joakim Kalantari; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transportation network modeling; hybrid transportation systems; transportation network optimization; transportation network simulation; transportation planning and control; Transportation networks; mixed model transportation;

   Sammanfattning : In transportation systems in general the issue of overcapacity coupled with low resource utilization has been identified for some time now. It has also been shown that the growth in transportation demand in the past is not absorbed by the existing overcapacity; rather the low levels of resource utilization are maintained. LÄS MER

4. 3. Spatial analysis and modeling of urban transportation networks

   Författare :Jingyi Lin; Yifang Ban; Sten Henning Hansen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Complex networks; transportation systems; network growth; Evolving networks; centrality; urban systems; topology; space syntax; spatial networks; distance effects; gravity laws; planarity; street network patterns; US airline system; China’s aviation system; network efficiency; cellular structure; hierarchy; network representations; Geodesy and Geoinformatics; Geodesi och geoinformatik;

   Sammanfattning : Transport systems in general, and urban transportation systems in particular, are the backbone of a country or a city, therefore play an intrinsic role in the socio-economic development. There have been numerous studies on real transportation systems from multiple fileds, including geography, urban planning, and engineering. LÄS MER

5. 4. Exploring patterns of empirical networks

   Författare :Luis E C Rocha; Petter Holme; Kimmo Kaski; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; complex systems; complex networks; network analysis; empirical networks; air transportation; consumer complaints; information technology; sexual contacts; epidemics; vaccination; Statistical physics; Statistisk fysik; Computational physics; Beräkningsfysik; Technology and social change; Teknik och social förändring; Epidemiology; Epidemiologi; Information technology; Informationsteknik; fysik; Physics; Statistics; statistik; Epidemiology; epidemiologi; Economics; nationalekonomi;

   Sammanfattning : We are constantly struggling to understand how nature works, trying to identify recurrent events and looking for analogies and relations between objects or individuals. Knowing patterns of behavior is powerful and fundamental for survival of any species. LÄS MER

7. 5. On Robust Distributed Control of Transportation Networks

   Författare :Gustav Nilsson; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traffic Signal Control; Distributed Control; Routing; Transportation Networks; Network Flows;

   Sammanfattning : With the ever-growing traffic demands, the transportation networks are getting more and more congested. While expanding these networks with more roads is both costly and in many cities not even feasible, the rapid development of new sensing and communication techniques has made it possible to perform control of transportation networks in real-time.
