2. 6. Urban Travel Time Estimation from Sparse GPS Data : An Efficient and Scalable Approach

   Author : Mahmood Rahmani; Harilaos Koutsopoulos; Nikolas Geroliminis; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; map-matching; path inference; sparse GPS probes; floating car data; arterial; urban area; digital road network; iterative travel time estimation; fixed point problem; Stockholm; taxi; Transportvetenskap; Transport Science;

   Abstract : The use of GPS probes in traffic management is growing rapidly as the required data collection infrastructure is increasingly in place, with significant number of mobile sensors moving around covering expansive areas of the road network. Many travelers carry with them at least one device with a built-in GPS receiver. READ MORE

4. 7. User Perspectives on Intelligent Transportation Systems

   Author : Jana Sochor; Harilaos Koutsopoulos; Misse Wester; Karl Kottenhoff; Amalia Polydoropoulou; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Intelligent Transportation Systems (ITS), or the advanced use of Information and Communication Technology (ICT) in the transportation context, offers new tools in the continual effort to develop an accessible, safe, and sustainable transportation system. In this thesis, focus is placed on ITS targeting individual use or the end users’ transportation experiences, e. READ MORE

5. 8. Modelling of Traffic Performance for Swedish Roads and Motorways

   Author : Per Strömgren; Harilaos Koutsopoulos; Nagui Rouphail; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rural highway; Intersection; Capacity; Critical gap; Flare; Micro simulation; Motorway; Ramp; Weaving; Merging; Queue; Delay; Over-saturated; Time-space; Roadwork zone; variable speed limit; harmonization; Transportvetenskap; Transport Science;

   Abstract : 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. READ MORE

6. 9. Demand Estimation and Bottleneck Management Using Heterogeneous Traffic Data

   Author : Athina Tympakianaki; Harilaos Koutsopoulos; Shlomo Bekhor; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transportvetenskap; Transport Science;

   Abstract : Congestion on urban and freeway networks has become a major problem, leading to increased travel times and reduced traffic safety. In order to suggest traffic management solutions to improve the transport system efficiency, it is important to capture the travel demand patterns, expressed as origin-destination (OD) matrices, and understand the mechanisms of traffic bottlenecks.
