  1. 1. Traffic State Estimation on Swedish Highways : Model Comparison using Multisource Data

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Jiaqi Xu; [2023]
    Nyckelord :Traffic State Estimation; Macroscopic Traffic Model; Extended Kalman Filter; Particle Filter; Data Fusion; Trafiklägesuppskattning; Makroskopisk trafikmodell; Utökad Kalman-filter; Partikelfilter; Datafusion;

    Sammanfattning : Due to the escalating demand for traffic information and management, the significance of traffic state estimation, which involves the assessment of traffic conditions on road segments with limited measurement data, is increasing. Two primary estimation methods are model-driven and data-driven. LÄS MER

  3. 2. 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

  4. 3. Evaluation the level of service at a roundabout : A case study on Al-Ibrahimeya roundabout in Alexandria, Egypt

    Kandidat-uppsats, KTH/Transportplanering

    Författare :Neval Iscan; [2019]
    Nyckelord :congestion; roundabout; simulation; VISSIM; SYNCHRO; delay; traffic signal; Alexandria;

    Sammanfattning : The capacity of today’s transportation network in Alexandria cannot handle the increasing number of vehicles. The root of traffic congestion in Alexandria is most likely as result of urban planning failure, an inadequate public transportation network, strong population growth, lack of enforcement of traffic laws, complex spatial street network and poor road quality.

  5. 4. Estimation of Hourly Origin Destination Trip Matrices for a Model of Norrköping

    Master-uppsats, Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska fakulteten

    Författare :Agnes Lindström; Frida Persson; [2018]
    Nyckelord :Visum; OD-estimation; SPSA; multiple linear regression; macroscopic modelling; traffic demand modelling;

    Sammanfattning : During the last century, the number of car users has increased as an effect of the increasing population growth. To manage the environmental and infrastructural challenges that comes with a more congested traffic network, traffic planning has become of higher importance to analyze the current traffic state and to predict future capacity challenges and effects of investments.

  7. 5. Development of a Logit model of the transition effect to public transport

    Master-uppsats, Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska högskolan

    Författare :Therése Ziedén; [2017]
    Nyckelord :Logit models; mode choice; mode shift; transition effect; Visum; parameter estimation; macro modelling;

    Sammanfattning : The importance of traffic planning has, throughout the years, been in- creased, providing sustainable developments of traffic and infrastructural investments. The analysis of the current traffic situation and the evalua- tion of the effects of a future investment are crucial for the socio-economic benefits maintenance. LÄS MER
