  1. 1. More Roads for the Money

    Author : Iman Mirzadeh; Björn Birgisson; George Feiger; KTH; []
    Keywords : ;

    Abstract : In order to keep the quality of the road networks at an acceptable level, large amount of investments for rehabilitation and maintenance activities are necessary in addition to investments in new and reconstructed roads. Therefore, an efficient allocation of road investment funds is of great economic importance. READ MORE

  2. 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

  3. 3. Automated Gravel Road Condition Assessment : A Case Study of Assessing Loose Gravel using Audio Data

    Author : Nausheen Saeed; Moudud Alam; Roger G. Nyberg; Diala Jomaa; Mirka Kans; Högskolan Dalarna; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Gravel roads; road maintenance; convolutional neural network CNN ; SVM; decision trees; ensemble bagged trees; GoogLeNet; ResNet50; ResNet18; sound analysis;

    Abstract : Gravel roads connect sparse populations and provide highways for agriculture and the transport of forest goods. Gravel roads are an economical choice where traffic volume is low. In Sweden, 21% of all public roads are state-owned gravel roads, covering over 20,200 km. READ MORE

  4. 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

  5. 5. Transport system optimization and pricing

    Author : Jan Owen Jansson; Handelshögskolan i Stockholm; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : How should the pricing principles prescribed by welfare economic theory be translated into operational pricing policy for different transport services? This question is considered for scheduled transport services in general, and for urban bus transport and cargo shipping in particular, for seaports and for highways. The second main question is: what would the financial result be in these cases of applying a pricing policy aimed at net social benefit mazimization? To answer this second question the tempting short-cut of assuming the whole supply-side as given, which is typical of the prevailing price theory, has to be resisted. READ MORE
