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

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

    Abstract : 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. READ MORE

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

    Author : Andreas Tapani; Jan Lundgren; Karl-Lennart Bång; Linköpings universitet; []
    Keywords : 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; Other technology;

    Abstract : 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. READ MORE

  5. 3. The use of highway crossings to maintain landscape connectivity for moose and roe deer

    Author : Mattias Olsson; Per Widén; Anthony Clevenger; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; wildlife crossings; Barrier effect; habitat selection; ecoduct; moose; roe deer; connectivity; conservation; overpass; underpass; highway; exclusion fencing; Biology; Biologi; Biology; Biologi;

    Abstract : Increasingly wildlife managers and land managers are challenged to maintain the viability and connectivity among large mammal populations. Thus, it is important that effective highway crossings are identified and optimized with respect to construction cost, facilitation of ungulate movements, and ability to reduce wildlife-vehicle collisions.

  6. 4. Fuel-Efficient Truck Platooning using Speed Profile Optimization

    Author : Sina Torabi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis is concerned with fuel-efficient driving strategies for heavy-dutyvehicles driving on highways with varying topography. A method for reducingthe fuel consumption of single trucks and platoons consisting of several trucksis described and evaluated both in simulation and in real trucks. READ MORE

  7. 5. Frost modelling and pavement temperatures : summer pavement temperaures and frost modelling

    Author : Åke Hermansson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Abstract : Three papers form the present thesis. In paper I a numerical model for calculation of surface temperatures on a highway is presented. The model takes all relevant factors into consideration, i.e. READ MORE
