  1. 1. Evaluation of Adaptive Traffic Signal Control Using Traffic Simulation : A case study in Addis Ababa, Ethiopia

    Master-uppsats, KTH/Transportplanering

    Författare :Aregay Fkadu Kebede; [2020]
    Nyckelord :: Traffic Congestion; Addis Ababa; Ethiopia; ITS; Traffic Signal; Timed Signal Operation; Adaptive Traffic Signal Controller; TUC; Microscopic Traffic Simulation; Optimization; TRANSYT; Average Delay.;

    Sammanfattning : One of the most significant urban transport problems is traffic congestion. All major cities both in developed and developing countries are facing the problem due to increasing travel demand caused by increasing urbanization and the attendant economic and population growth.

  2. 2. Tillståndsbaserat underhåll av spårväxlar genom statistisk processtyrning : En fallstudie enligt DMAIC

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik och samhälle; Luleå tekniska universitet/Institutionen för ekonomi, teknik och samhälle

    Författare :Caroline Hägglund; Oscar Jonsson; [2019]
    Nyckelord :condition-based maintenance; maintenance; DMAIC; point; switches and crossings; statistical proces control; SPC; switches; railway; DMAIC; järnväg; spårväxel; statistisk processtyrning; SPS; tillståndsbaserat underhåll; underhåll;

    Sammanfattning : Switches, which are critical components of the Swedish railway, have a neglected maintenance cost that is three times as high as their current annual maintenance cost. Between 2017 and 2018, switches’ reported faults increased by 38 % and about one-third of them caused delays on the regular railway traffic. LÄS MER

  3. 3. Evaluation of Signal Optimization Software : Comparison of Optimal Signal Pans from TRANSYT and LinSig – A Case Study

    Master-uppsats, KTH/Transportplanering

    Författare :EVANS OTIENO ODHIAMBO; [2019]
    Nyckelord :TRANSYT; LinSig; Delay; Practical Reserve Capacity; Optimal cycle time; Optimization.;

    Sammanfattning : The design of traffic signal control plan is directly related to the level of traffic congestion experienced both at the junction level and the network particularly in urban areas. Ensuring signals are well designed is one of the most cost-effective ways of tackling urban congestion problems. LÄS MER

  4. 4. Centralisering av personalplanering : En fallstudie om effektivisering och processtyrning

    Kandidat-uppsats, Uppsala universitet/Institutionen för teknikvetenskaper

    Författare :Nina Eriksson; [2019]
    Nyckelord :LEAN; streamlining; process flow chart; interview; survey; LEAN; effektivisering; processflödeskarta; intervju; enkät;

    Sammanfattning : Keolis conducts public transport on behalf of municipalities around the country. Through locally adapted and sustainable city traffic, Keolis creates value for travelers, society and owners. The company has been wholly owned by the international public transport group Keolis since the autumn of 2010. LÄS MER

  5. 5. Effectiveness of a speed advisory traffic signal system for Conventional and Automated vehicles in a smart city

    Master-uppsats, Linköpings universitet/Kommunikations- och transportsystemLinköpings universitet/Tekniska fakulteten

    Författare :Hossam Anany; [2019]
    Nyckelord :Traffic management; Micro simulation; Traffic flow efficiency Travel time - trip delay ; Green Light Optimal Speed Advisory GLOSA ; V2I communication; Conventional vehicles; connected vehicles; Automated vehicles; Mixed Traffic Environment; smart cities;

    Sammanfattning : This thesis project presents a traffic micro simulation study that investigates the state-of-the-art in traffic management "Green Light Optimal Speed Advisory (GLOSA)" for vehicles in a smart city. GLOSA utilizes infrastructure and vehicles communication through using current signal plan settings and updated vehicular information in order to influence the intersection approach speeds. LÄS MER
