  • Combining speed and acceleration to detect reckless driving in the informal public transport industry 

    Zeeman, A. S.; Booysen, Marthinus J. (IEEE -- Institute of Electrical and Electronics Engineers, 2013-10)
    The informal transport industry in Sub-Saharan Africa is notoriously dangerous, leading to many fatalities annually. This paper presents an innovative way of monitoring driver behaviour, in real-time, by taking into ...

  • Household electricity and water monitor and control with cellular communications and web interface 

    Muller, R. I.; Booysen, Marthinus J. (IEEE -- Institute of Electrical and Electronics Engineers, 2014-01)
    The availability and depletion of natural resources is increasingly punted as the limiting factor for sustainability. A lot of focus is currently placed on the role and effect of fossil fuels as well as water conservation. ...

  • Impact of Neighbor Awareness at the MAC Layer in a Vehicular Ad-hoc NETwork (VANET) 

    Booysen, Marthinus J.; Zeadally, Sherali; Van Rooyen, Gert-Jan (IEEE -- Institute of Electrical and Electronics Engineers, 2013-06)
    Despite various proposed Medium Access Control (MAC) approaches, efficient medium access in VANET remains a significant challenge, especially for the broadcast of safety messages. A key contributing factor to packet ...

  • Informal public transport in Sub-Saharan Africa as a vessel for novel intelligent transport systems 

    Booysen, Marthinus J.; Andersen, S. J.; Zeeman, A. S. (IEEE -- Institute of Electrical and Electronics Engineers, 2013-10)
    Developed countries have lead the way in the implementation of Intelligent Transport Systems, with the objectives of improving safety, efficiency, and environmental impact of transport. With the developing world entering ...

  • Left ventricular segmentation from MRI datasets with edge modelling conditional random fields 

    Dreijer, Janto F.; Herbst, Ben M.; Du Preez, Johan A. (BioMed Central, 2013-07)
    Background: This paper considers automatic segmentation of the left cardiac ventricle in short axis magnetic resonance images. Various aspects, such as the presence of papillary muscles near the endocardium border, makes ...

  • Machine-to-machine (M2M) communications in vehicular networks 

    Booysen, Marthinus J.; Gilmore, J. S.; Zeadally, Sherali; Van Rooyen, Gert-Jan (Korea Society of Internet Information (KSII), 2012-02)
    To address the need for autonomous control of remote and distributed mobile systems, Machine-to-Machine (M2M) communications are rapidly gaining attention from both academia and industry. M2M communications have recently ...

  • Minibus driving behaviour on the Cape Town to Mthatha Route 

    Booysen, Marthinus J.; Ebot, N. A.; Akpa, E. N. O. (Southern African Transport Conference, 2014-07)
    Minibus taxis are considered to be notoriously dangerous and are seen as the epitome of bad driving in South Africa in particular, and Sub-Saharan Africa in general. Minibus taxis are used for long-distance and urban travel. ...

  • A performance comparison of media access control protocols for vehicular ad-hoc networks (VANETs) 

    Booysen, Marthinus J.; Zeadally, Sherali; Van Rooyen, Gert-Jan (The Institution of Engineering and Technology (IET), 2012-04)
    The emergence of computationally rich vehicles and recent advances in wireless communication technologies are fueling vehicular network research in industry and academia. A key challenge to the successful deployment of ...

  • Public transport sector driver behaviour : measuring recklessness using speed and acceleration 

    Zeeman, Adriaan Siebrits; Booysen, Marthinus J. (Southern African Transport Conference, 2014-07)
    The informal transport industry in Sub-Saharan Africa is notoriously dangerous, leading to many fatalities annually. This paper presents an innovative way of monitoring driver behaviour, in real-time, by taking into account ...

  • The relevance of Intelligent Transport Systems (ITS) in sub-sub-Saharan Africa 

    Booysen, Marthinus J. (Development Bank of Southern Africa, 2013-07)
    Countries like the United States, Japan, and a number of countries in Europe, have led the way in a field that has become known as Intelligent Transportation Systems. The term broadly describes any intelligent intervention ...

  • Remotely controllable wireless road stud network 

    Le Roux, J. H.; Barnard, A.; Booysen, Marthinus J. (IEEE -- Institute of Electrical and Electronics Engineers, 2013-10)
    Developing countries face many infrastructure related challenges, one of them being road safety. This paper proposes a novel system introducing a network of wirelessly connected road studs that are remotely controllable ...

  • Simple capacitive seat sensing for occupancy detection and passenger counting in minibus taxis 

    Zeeman, Adriaan Siebrits; Booysen, Marthinus J. (Southern African Transport Conference, 2014-07)
    The informal public transportation sector in Sub-Saharan Africa contributes significantly to public transport, and yet little is known about passenger mobility patterns. We propose a low cost system to measure occupancy ...

  • Survey of Media Access Control (MAC) protocols for Vehicular Ad hoc NETworks (VANETs) 

    Booysen, Marthinus J.; Zeadally, Sherali; Van Rooyen, Gert-Jan (The Institution of Engineering and Technology (IET), 2011-07)
