  1. 1. Dynamic Modelling of Transit Operations and Passenger Decisions

    Författare :Oded Cats; Haris Koutsopoulos; Tomer Toledo; Wilson Nigel; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Public Transport; Transit Operations; Simulation Model; Traffic Simulation; Route Choice; Dynamic Model; Assignment Model; Control; SRA - Transport; SRA - Transport;

    Sammanfattning : Efficient and reliable public transport systems are fundamental in promoting green growth developments in metropolitan areas. A large range of Advanced Public Transport Systems (APTS) facilitates the design of real-time operations and demand management. LÄS MER

  3. 2. Modelling and Appraisal in Congested Transport Networks

    Författare :Jens West; Maria Börjesson; Oded Cats; Leonid Engelsson; Giulio Cantarella; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transport modelling; Transit Assignment; Appraisal; Congestion; Crowding; Cost-benefit analysis; Value of time; Congestion charge; Dynamic traffic assignment; Transportvetenskap; Transport Science;

    Sammanfattning : Appraisal methodologies for congestion mitigation projects are relatively less well developed compared to methodologies for projects reducing free flow travel times. For instance, static assignment models are incapable of representing the build-up and dissipation of traffic queues, or capturing the experienced crowding caused by uneven on-board passenger loads.

  4. 3. Hierarchical Modeling of Road Traffic Networks

    Författare :Eugene Merritt; KTH; []
    Nyckelord :traffic simulation models; calibration and validation; field data collection;

    Sammanfattning : The main objective of the thesis was to develop and applymethodologies for analysis and evaluation of the applicabilityof different types of road traffic simulation models for urbantraffic conditions. For this purpose a number of models ofmacroscopic, mesoscopic and microscopic type were applied,calibrated, validated and analyzed using extensive field datacollection to obtain traffic flow, travel time and queue-lengthdata for major road networks in Stockholm and Uppsala.

  5. 4. Origin-destination matrix estimation from traffic counts

    Författare :Anders Peterson; Henrik Edwards; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : For most kind of analyses in the field of traffic modeling, there is a need for origin-destination (OD) matrices, which specify the travel demands between the origin and destination nodes in the network. The process of obtaining OD-matrices is long, complicated and expensive. LÄS MER

  7. 5. Congestion Charging in Urban Networks : Modelling Issues and Simulated Effects

    Författare :Ida Kristoffersson; Leonid Engelson; Otto Anker Nielsen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transport Modelling; Congestion Charging; Departure Time Choice; Dynamic Traffic Simulation; Welfare Effects; Equity;

    Sammanfattning : One of the major challenges cities face today, in their development towards sustainable urban areas, is the need for an efficient and environmentally friendly transport system. This transport system should manage to tie together the city without strong adverse impact on urban environment, air-quality and climate change. LÄS MER
