  1. 1. 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

  2. 2. Modelling of Traffic Performance for Swedish Roads and Motorways

    Författare :Per Strömgren; Harilaos Koutsopoulos; Nagui Rouphail; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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;

    Sammanfattning : 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. LÄS MER

  3. 3. A methodology for operations-based safety appraisal of two-lane rural highways : Application in Uganda

    Författare :Godfrey Mwesige; Harilaos Koutsopoulos; Basil Psarianos; KTH; []
    Nyckelord :passing zones; passing rate; collision risk; accepted gap; time-to-collision; passing sight distance; two-lane rural highways; Uganda; Transportvetenskap; Transport Science;

    Sammanfattning : The majority of the road infrastructure in developing countries consists oftwo-lane highways with one lane in each travel direction. Operational efficiency of these highways is derived fromintermittent passing zones where fast vehicles are permitted by design to pass slow vehicles using the opposite traffic lane. LÄS MER

  4. 4. Road construction materials as a source of pollutants

    Författare :Åsa Lindgren; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traffic Engineering; Trafikteknik;

    Sammanfattning : This thesis deals mainly with road construction materials, particularly in cases where they may contribute polluting substances. The complexity of the measuring and evaluation of some pollutants with respect to sampling and chemical analysis is considered. LÄS MER

  5. 5. Vehicular Communication in Obstructed and Non Line-of-Sight Scenarios

    Författare :Dimitrios Vlastaras; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicle-to-Vehicle Communications; Channel Modeling; Vehicular Communication; Truck Obstruction; Channel Emulation; Radar; 802.11p; Car; Truck; Accident Avoidance; V2V; V2I; C2C; V2X;

    Sammanfattning : Since the invention of the first car available to masses, the 1908 Ford Model T, technology has advanced towards making car travel safer for occupants and bystanders. In recent years, wireless communication has been introduced in the vehicular industry as a means to avoid accidents and save lives. LÄS MER
