1. 1. Moving in the dark : Mathematics of complex pedestrian flows

   Magister-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Författare :Meghashyam Veluvali; [2023]
   Nyckelord :Mathematical modelling of pedestrian dynamics; stochastic systems; evacuation time; random walk method; parabolic equation; finite difference method;

   Sammanfattning : The field of mathematical modelling for pedestrian dynamics has attracted significant scientific attention, with various models proposed from perspectives such as kinetic theory, statistical mechanics, game theory and partial differential equations. Often such investigations are seen as being a part of a new branch of study in the domain of applied physics, called sociophysics. LÄS MER

3. 2. The Development of A Simple Engineering Calculation Method for Wildfire Scenarios

   Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Muthia Khairunisa Jaelani; [2022]
   Nyckelord :Wildfire; evacuation; WUI fire; evacuation modelling; traffic modelling; Technology and Engineering;

   Sammanfattning : Emergency planning is required to respond to the increasing wildfire threat. A part of this is to assess a community’s capacity to move to a safe place during wildfires. This can be achieved by calculating the time it takes for a community to evacuate from an at-risk area to a relatively safe place. LÄS MER

   Sammanfattning : Is it possible to increase traffic flows and decrease stand stills in rush hour traffic by tweaking existing traffic light signals? A vehicle’s engine running on idle is not useful in physical terms and emits unnecessary exhausts. By investigating and observing signal phase times on site in Hangzhou, China, an effort was made to find out if it was possible to get better flow and thus lower emissions by changing the traffic signal programs.

5. 4. Validation of WUI-NITY compared to real-world data

   Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Jonatan Edenvik; [2022]
   Nyckelord :Wildland urban interface; Wildfires; Community evacuation; Real-world simulation; WUI-NITY; PeMS; Pedestrian simulation; Traffic simulation; Technology and Engineering;

   Sammanfattning : This thesis compares the wildfire evacuation simulation programme, WUI-NITY, against real-world data by analysing and comparing three wildfire events of the past. The wildfire events were all limited to be within the state of California and was further analysed based on the available quality of data derived of the chosen database. LÄS MER

7. 5. Testing macroscopic traffic evacuation models for wildland-urban interface fires

   Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Adam Ardinge; [2021]
   Nyckelord :WUI-NITY; WUI; V V; traffic evacuation; WUI fire evacuation; simulation model; verification testing; validation testing; Kincade; Technology and Engineering;

   Sammanfattning : This thesis presents the verification and validation testing performed on the evacuation simulation platform WUI-NITY which has the aim of being a simulation tool for the integration of different layers, such as pedestrian, traffic and wildfire with evolving dynamic interactions. The present thesis aims at applying a set of verification tests and validation testing suitable for WUI-NITY with a focus on the traffic component. LÄS MER
