  2. 1. Evaluation of Road Equipment with Emphasis on Condition Assessment

    Author : Sven-Olof Lundkvist; Ulf Isacsson; Rolf Magnusson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Road equipment; Condition assessment; State-of-the-art; Mobile measurement; Road marking; Road sign; Post delineator; Traffic light; Street lighting; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

    Abstract : This doctoral thesis deals primarily with condition assessment of road equipment. The road equipment concept is defined by five main groups, road lighting, fences and barriers, vertical signs, horizontal signs and traffic signals, respectively. READ MORE

  4. 2. Distributed Road Grade Estimation for Heavy Duty Vehicles

    Author : Per Sahlholm; Karl Henrik Johansson; Emilio Frazzoli; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automotive; estimation; distributed systems; automatic control; heavy duty vehicles; road grade; road maps; Automatic control; Reglerteknik;

    Abstract : An increasing need for goods and passenger transportation drives continued worldwide growth in traffic. As traffic increases environmental concerns, traffic safety, and cost efficiency become ever more important. Advancements in microelectronics open the possibility to address these issues through new advanced driver assistance systems. READ MORE

    Author : Malin Löfsjögård; KTH; []
    Keywords : concrete; roads; functional properties; optimisation model; road lighting; joint performance;

    Abstract : The roads constitute a major part of the nation’sinfrastructure. For the society and the individuals it isimportant with a well functioning road network. To sustain theimpact from traffic intensity and heavy loads durable pavementsare demanded. READ MORE

  6. 4. Iterative Road Grade Estimation for Heavy Duty Vehicle Control

    Author : Per Sahlholm; Karl Henrik Johansson; Jonas Sjöberg; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; road grade; estimation; heavy duty vehicle; Kalman filter; automatic control; Automatic control; Reglerteknik;

    Abstract : This thesis presents a new method for iterative road grade estimation based on sensors that are commonplace in modern heavy duty vehicles. Estimates from multiple passes of the same road segment are merged together to form a road grade map, that is improved each time the vehicle revisits an already traveled route. READ MORE

  7. 5. Light Design : Outdoor Urban Public Places : - Urban Lighting: Design and Technologies -

    Author : José Nuno Sampaio; Björn-Erik Erlandsson; Izael Pereira Da Silva; KTH; []
    Keywords : Light-based Technologies and Design; Energy Technology; Energiteknik;

    Abstract : Most of the present time outdoor lighting investments seem to be focused on road and automotive traffic facilities or oriented toward safety, security and efficiency. We can identify this in many of the world cities, as a globally spread common practice, where lighting is still highly perceived as a pure matter of quantities’ distribution.
