  • Development of a map-matching algorithm for dynamic sampling rate GPS signals to determine vehicle routes on a MATSim network 
    Vosloo, Jacobus B. (University of Pretoria, 2018)
    The rapid development and proliferation of GPS-enabled systems and devices has led to a significant increase in the availability of transport data, more specifically GPS trajectories, that can be used in researching ...
  • The development of a metric for the accessibility and affordability of transport in South Africa 
    De Hoog, Jeanette; University of Pretoria. Faculty of Engineering, Built Environment and Information Technology. Dept. of Industrial and Systems Engineering (University of Pretoria. Faculty of Engineering, Built Environment and Information Technology. Dept. of Industrial and Systems Engineering, 2012)
    Accessibility and a ordability of transport have a major impact on the people living in a country. Accessibility is de ned as the ease with which people are able to reach activities or destinations (Litman, 2010a), whilst ...
  • Heuristics for large-scale Capacitated Arc Routing Problems on mixed networks 
    Willemse, Elias J. (University of Pretoria, 2016)
    Residential waste collection is an expensive activity performed daily on large metropolitan areas throughout the year. Even a small improvement in waste collection and transfer operations can therefore lead to signi cant ...
  • Implementing MATSim Transit Simulation 
    Wevell, Dennis; University of Pretoria. Faculty of Engineering, Built Environment and Information Technology. Dept. of Industrial and Systems Engineering (University of Pretoria.

  • Improving hospital bed utilisation through simulation and optimisation in South African Public Hospitals 
    Bloem, Connie; University of Pretoria. Faculty of Engineering, Built Environment and Information Technology. Dept. of Industrial and Systems Engineering (University of Pretoria. Faculty of Engineering, Built Environment and Information Technology. Dept. of Industrial and Systems Engineering, 2015-05-13)
    South African public hospitals have a shortage of beds and struggle to allocate patients to beds and keep track thereof. This causes inefficient utilisation of limited bed capacity. This report addresses this problem by ...
  • An initial implementation of a multi-agent transport simulator for South Africa 
    Fourie, P.J. (Pieter Jacobus) (University of Pretoria, 2009-09-18)
    Transport demand planning in South Africa is a neglected field of study, using obsolete methods to model an extremely complex, dynamic system composed of an eclectic mix of First and Third World transport technologies, ...
