1. 1. Monitoring winter road friction using floating car data

   Författare :Sofia Sollén; Johan Casselgren; Mikael Sjödahl; Hawzheen Karim; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Floating Car Data; Winter Road Maintenance; Tire-to-Road Friction; Road Safety; Vision Zero; Intelligent Transport Systems; Experimental Mechanics; Experimentell mekanik;

   Sammanfattning : More than a million people die every year due to road traffic accidents globally where one in five serious or fatal accidents occurs during severe weather conditions. Sweden is in the lead of Vision Zero, with the aim of zero casualties due to road traffic, and every year new countries and organisations accept the challenge of saving lives. LÄS MER

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

   Författare :Mahmood Rahmani; Harilaos Koutsopoulos; Nikolas Geroliminis; KTH; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

4. 3. The Principle of Scaling of Geographic Space and its Application in Urban Studies

   Författare :Xintao Liu; Bin Jiang; Yifang Ban; Meng Liqiu; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; geographic space; scaling; GIScience; VGI; OSM; heavy-tailed distribution; the head tail division rule; space syntax; nature street; urban sprawl; floating car data; hierarchical spatial structure;

   Sammanfattning : Geographic space is the large-scale and continuous space that encircles the earth and in which human activities occur. The study of geographic space has drawn attention in many different fields and has been applied in a variety of studies, including those on cognition, urban planning and navigation systems. LÄS MER

5. 4. Energy Usage in Supermarkets - Modelling and Field Measurements

   Författare :Jaime Arias; Per Lundqvist; Denis Clodic; KTH; []
   Nyckelord :Supermarket; Energy Performance; System Analysis; Modelling; Simulation; Field Measurements; Refrigeration Systems; Indirect Systems; Heat Recovery; Floating Condensing; TEWI; LCC.; NATURAL SCIENCES; NATURVETENSKAP;

   Sammanfattning : This thesis investigates a special type of energy system, namely energy use in supermarkets through modelling, simulations and field studies. A user-friendly computer program, CyberMart, which calculates the total energy performance of a supermarket, is presented. LÄS MER

7. 5. Path Inference of Sparse GPS Probes for Urban Networks : Methods and Applications

   Författare :Mahmood Rahmani; Harilaos Koutsopoulos; Clas Rydergren; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; map-matching; path inference; sparse GPS probes; FCD; urban area; digital road network; Stockholm; taxi; iMobility Lab; MapViz; travel time; SRA - Transport; SRA - Transport;

   Sammanfattning : The application of GPS probes in traffic management is growing rapidly as the required data collection infrastructure is increasingly in place in urban areas with significant number of mobile sensors moving around covering expansive areas of the road network. Most travelers carry with them at least one device with a built-in GPS receiver. LÄS MER
