   Abstract : Today, the main research field for the automotive industry is to find solutions for active safety. In order to perceive the surrounding environment, tracking nearby traffic objects plays an important role. READ MORE

3. 7. Numerical and experimental dynamic analyses of the Vega Pedestrian bridge including seasonal effects

   University essay from KTH/Bro- och stålbyggnad

   Author : John Peter Hallak Neilson; [2019]
   Keywords : Structural dynamics; Timber structures; Seasonal effects; Asphalt; Footbridges; Arch bridges; Dynamic analysis;

   Abstract : As timber structures become increasingly relevant and sought after – since they enable improvements in building time while reducing a structure’s life cycle impacts – streamlining their design can have meaningful economic and environmental implications. For timber footbridges, its design is frequently governed by serviceability criteria linked to excessive vibrations. READ MORE

4. 8. Pedestrian Evacuation Modelled by a Conservation Law with a Two-inflection-point Flux Function

   University essay from Lunds universitet/Matematik LTH

   Author : Henrik Lindell; [2019]
   Keywords : Numerical analysis; Applied mathematics; Hyperbolic conservation laws; Finite volume methods; Partial differential equations; Pedestrian dynamics; Modeling; Mathematics and Statistics;

   Abstract : When designing a building one must consider safety aspects. One such aspect is that in the case of an emergency people should be able to efficiently evacuate the building. In this paper we investigate how the width-profile of a corridor leading to an exit might affect the efficiency of evacuation. READ MORE

5. 9. Dynamic Assessment of Footbridges : A designer's method to estimate running induced vibrations

   University essay from KTH/Bro- och stålbyggnad

   Author : Jones Södergren; Anton Barraza; [2018]
   Keywords : Footbridge Dynamics; Running; Load; Vibrations; Structural Dynamics; Human Structure Interaction; Dynamic Assessment; Acceleration;

   Abstract : Dynamic problems in footbridges, such as sensible vibrations caused by human induced loading, has on a number of occasions been observed. These vibrations are rarely an ultimate limit state problem, but can be perceived as unpleasant by the pedestrian. In design guidelines there are propositions for how to asses the dynamic problem.

6. 10. Experimental study on effective width through openings using Kinect

   University essay from Lunds universitet/Avdelningen för Brandteknik

   Author : Juan Manuel Chaves Posada; [2018]
   Keywords : Kinect; Effective Width; Effective Width Through Openings; Boundary Layer; Flow Through Openings; Pedestrian Tracking; Low-Density Flows; Pedestrian Dynamics; Technology and Engineering;

   Abstract : The effective width model was introduced to show how the flow was linearly proportional to the effective width on stairwells accounting for the edge effect as well as lateral body sway. In this sense, small increments on the width of the stairwell were proven to increment the flow through it in a linear manner. READ MORE
