  1. 1. A model for simulation and generation of surrounding vehicles in driving simulators

    Författare :Johan Olstam; Jan Lundgren; Pontus Matstoms; Stéphane Espié; Linköpings universitet; []
    Nyckelord :Traffic; Simulation; Model; Traffic flow; Vehicle; Micro; Overtaking; Vehicle spacing; Deceleration; Acceleration; Mathematical model; Simulator; Road: Traffic theory; Road: Traffic theory; Technology; Traffic Simulation; Driving Simulator; Traffic Generation; Microscopic; Traffic models; TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Driving simulators are used to conduct experiments on for example driver behavior, road design, and vehicle characteristics. The results of the experiments often depend on the traffic conditions. One example is the evaluation of cellular phones and how they affect driving behavior. LÄS MER

  2. 2. Traffic Simulation Modelling of Rural Roads and Driver Assistance Systems

    Författare :Andreas Tapani; Jan Lundgren; Haris N. Koutsopoulos; Linköpings universitet; []
    Nyckelord :Traffic; Micro; Simulation; Model; Car following; Rural road; Driver; Fatigue; Rumble strip; Adaptive cruise control; Active safety system; Safety; Evaluation; Overtaking; Traffic lane; Mathematical model; Thesis; Road: Traffic theory; Road: Traffic theory; Microscopic traffic simulation; Rural Traffic Simulator RuTSim ; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Microscopic traffic simulation has proven to be a useful tool for analysis of varioustraffic systems. This thesis consider microscopic traffic simulation of rural roads andthe use of traffic simulation for evaluation of driver assistance systems. LÄS MER

  3. 3. Road traffic metals : sources and emissions

    Författare :David Hjortenkrans; Bo Bergbäck; Per-Arne Malmqvist; Högskolan i Kalmar; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Emission patterns; Heavy metals; Roadside soil; Sweden; Traffic; Sequential extractions; SFA; Environmental chemistry; Miljökemi; Environmental Chemistry; Miljökemi;

    Sammanfattning : As the environmental regulations and technical progress have forced the factories’ old “end of pipe” solutions to improve, the metal emissions from point sources have decreased. Instead, the diffuse consumption emissions from goods in use now are in focus. LÄS MER

  4. 4. A Traffic Simulation Modeling Framework for Rural Highways

    Författare :Andreas Tapani; Jan Lundgren; Karl-Lennart Bång; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traffic; Micro; Simulation; Model; Overtaking; Speed; Headway; Rural road; Electronic driving aid; Mathematical model; Road: Traffic theory; Road: Traffic theory; Traffic Simulation; Rural Highway; Level-of-Serivice; Road safety; safety indicators; Advanced Driver Assistance Systems ADAS ; Other technology; Övriga teknikvetenskaper;

    Sammanfattning : Models based on micro-simulation of traffic flows have proven to be useful tools in the study of various traffic systems. Today, there is a wealth of traffic microsimulation models developed for freeway and urban street networks. The road mileage is however in many countries dominated by rural highways. LÄS MER

  5. 5. Trafikslag på undantag : Cykeltrafiken i Stockholm 1930-1980

    Författare :Martin Emanuel; Arne Kaijser; Mikael Hård; KTH; []
    Nyckelord :HUMANITIES; HUMANIORA; HUMANIORA; HUMANITIES; bicycle traffic; bicycle planning; city traffic regime; Copenhagen; Denmark; history; history of technology; ideology; materialised interpretation; representation; Stockholm; Sweden; traffic engineering; traffic planning; traffic policy; 20th century; urban history; urban planning; 1900-talet; cykeltrafik; cykelplanering; Danmark; ideologi; Köpenhamn; materialiserad tolkning; representation; stadshistoria; stadsplanering; stadstrafikregim; Stockholm; Sverige; teknikhistoria; trafikteknik; trafikplanering; trafikpolitik;

    Sammanfattning : The modal share of bicycle traffic in Stockholm increased from 20 per cent to over 30 per cent during the 1930s, and reached staggering levels during World War Two – peaking at over 70 per cent. Soon after the war, however, the share declined rapidly. LÄS MER
