Simulation-based optimisation of public transport networks
Public transport network design deals with finding the most efficient network solution among a set of alternatives, that best satisfies the often-conflicting objectives of different network stakeholders like passengers and operators. Simulation-based Optimisation (SBO) is a discipline that solves …

A study into scalable transport networks for IoT deployment
… automation, smart healthcare systems, autonomous transportation to name just a few. These applications have dramatically improved the way we live as citizens. While the internet is continuing to grow at an unprecedented rate, this has also been coupled with the growing demands for new services …

Theoretical investigations into competition, regulation, and integration in transport networks
… the literature and some of the key issues in UK transport. We identify a need to discourage car use and the role that public transport plays in this. We discuss the various options available to policymakers to reduce problems of congestion and pollution. We note how the emphasis on deregulation …

Deep Learning Models for Traffic Prediction in Urban Transport Networks.
… important component of this vision is the urban transport network which is continuously challenged with increasing number of vehicles on roads. This results in issues including long travel time, increasingly persistent traffic congestion, accidents and road safety concerns. The research work in …

Non-Binary Coded Modulation for FMF-Based Coherent Optical Transport Networks
The Internet has fundamentally changed the way of modern communication. Current trends indicate that high-capacity demands are not going to be saturated anytime soon. From Shannon's theory, we know that information capacity is a logarithmic function of signal-to-noise ratio (SNR), but a linear …

Resource allocation and modeling in spectrally and spatially flexible optical transport networks
… to be endlessly growing, yet the capacity of the networks that underpin that connectivity is anything but endless. This thesis explores both short and long term solutions for increasing the capacity of the largest and most capacious of these networks, the backbones upon which the Internet is …

Case study analysis of integrated public transport networks in five South African cities
… embarked on implementing Integrated Public Transport Networks (IPTN’s) guided by the Public Transport Strategy and Action Plan (PTSAP) published by the National Department of Transport (NDoT). The PTSAP sought to reform public transport industries across South Africa by 2020 to ward off …

A Mass Minimizing Flow for Real-Valued Flat Chains with Applications to Transport Networks
An oriented transportation network can be modeled by a 1-dimensional chain whose boundary is the difference between the demand and supply distributions, represented by weighted sums of point masses. To accommodate efficiencies of scale into the model, one uses a suitable Mα norm for transportation …

Transfer Optimization in Public Transport Networks: Timetable Synchronization, Operational Control and a New Service-Design Concept
Unreliable public transport (PT) service is one of the main reasons to reduce substantially the attractiveness of PT service. As a result, continued unreliable PT service will not only frustrate the existing passengers, but will also cause a loss of potential new users. Transfer synchronization is …

A geospatial investigation of destination choice modelling. The case of the MYCITI integrated rapid transit bus system, Cape Town, South Africa
The transport sector plays an integral role in a country's development and economy. Optimised transport networks and infrastructure can lead to increased economic development. Effective transport networks and public transportation systems are, therefore, essential to growing the South African …

Accessing public transport, a comparative study of Berlin and London
… European capital cities with extensive public transport networks. The main motivation for this study stemmed from my extensive experience travelling around independently in both cities on public transport as a totally blind person. I wanted to gain a much greater insight into, and understanding …

Control architecture of survivable multi-domain optical networks
Optical networks have been widely adopted as the transport network in research industry for years. To better utilize the high speed benefit of optical transport networks, control architecture have become the focus of research in recent years. In this thesis, I have developed a control plane …

Understanding travel mode choice: A new approach for city scale simulation
… behaviour is key to effective management of transport networks, many of which are under increasing strain from rising travel demand. Conventional approaches to simulating mode choice typically make use of behavioural models either derived from stated preference choice experiments or …

Bus network sketch planning with origin-destination travel data
Public transport plays an important role in urban mobility. Public transport planners seek to improve existing public transport networks to better serve existing passengers and recruit new passengers, particularly as demand patterns change with evolving demographics and land use. One strategy for …

The role of transport and communications in regional economic development : the case of Chana and Lundazi district of Eastern Province
The role of transport and communications in Regional Economic Development: the case of Chama and Lundazi districts of Eastern Province. This paper examines the implications of improvements in the transport and communications systems on the economic development of the two districts, which are …

The role of private participation in enhancing the Indian transport sector
The Indian transport sector, one of the largest transport networks in the world, faces some serious issues. These may be identified as follows: * Unmet demand for service and infrastructure * Conflicting responsibilities * Inadequate resource mobilization * Poor Asset Management * Inadequate …

Active flows and networks
… physical, biological, or information transport networks are driven by small-scale local energy input. In the first part of this thesis, we introduce and explore two analytically tractable nonlinear models for such active flow networks, drawing motivation from recent microfluidic …

Integration of transport systems in the UK: fact, fiction or fantasy?
The study of integrated transport systems is not new; indeed in the UK there is a Commission for Integrated Transport (CfIT:2006) which was set up in 1998 by the Government to assist in developing its transport policy including pursuing a sustainable transport agenda. It is an independent body …

Potential impacts of hard infrastructure development on agricultural trade
… agricultural trade. Good quality physical networks could reduce the transport costs for producers and suppliers, thereby increasing the volume of agricultural bilateral trade. For most countries, tariff rates, transport costs, geographic drawbacks, and other nontariff barriers are …
