Factors influencing bus network design
Bus network design and frequency setting, the highest level subproblems in the bus planning process, have long-term impacts on bus network performance. Improving network performance not only improves the attractiveness of public transport and thus ridership, but cost-effectiveness as well because …

Optimizing feeder bus network based on access mode shifts
… this dissertation is to optimally find a feeder bus network in a suburban area for an existing rail system that connects the suburban area with the Central Business District (CBD). The objective is to minimize the total cost, including user and supplier costs. Three major access modes (walk, …

Bus network sketch planning with origin-destination travel data
… 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 network improvement is to add new routes, which can improve service by reducing …

An investigation into the importance of considering protection performance during power system out-of-step conditions
… during out-of-step conditions. A nine-bus IEEE benchmark network was chosen for the purposes of the research. The nine-bus network is representative, simple and small. It is a benchmark which is often used in comparative studies in the power system field. The nine-bus network data taken …

Predicting Ridership and Travel Time Impacts of Bus Service Changes Using Sketch Planning Methods
Bus service changes range in scale, and understanding their impacts on ridership and travel times can inform decision-making as changes are considered for the bus network. Budgetary limitations are at the heart of service change decisions, resulting in the need for analysts to assess different …

Possibilities for DERs: Evaluating Existing and New Models for DER Participation
… – New England (ISO-NE) were modeled onto a 30-bus network, and simulated using historical data of load demand from each Independent System Operator. The performance of these models in key metrics of average cost paid per node and the uptake of DERs were compared to the same systems under a …

Graph Theoretical Modelling of Electrical Distribution Grids
… graph theory towards the electrical distribution networks that transmit electricity from the generators that produce it and the consumers that use it. Specifically, we establish the substation and bus network as graph theoretical models for this major piece of electrical infrastructure. We also …

Neural bus networks
Bus schedules are unreliable, leaving passengers waiting and increasing commute times. This problem can be solved by modeling the traffic network, and delivering predicted arrival times to passengers. Research attempts to model traffic networks use historical, statistical and learning based models, …

Detecting and quantifying bus operation impedance : the balance between reliability and speed
This thesis explores the phenomenon of bus impedance, defined as a slowing down of bus operations for customers. Impedance can stem from an overemphasis on reliability to the detriment of speed in bus operations. Public transport agencies aim at achieving the best balance between speed and …

An Approach to Automotive Electrification and Testing
… was changed from a conventional internal combustion engine with a start/stop capability, to a fully electric Powertrain, with a diesel generator, and plug in charging capability. This paper will cover the electrical work performed on the vehicle during the summer prior to year three of the …

Real-data modelling of transportation networks
… applications of Markov chains in transportation networks. We model bike sharing systems, bus networks, and multi-modal public transportation networks using Markov chains. The validation of the models is done by using real data from Boston and London for the bike sharing systems and the …

Damping of electromechanical oscillations using power system stabilizers
… control structure of the PSS and the design of robust PSS. We develop two new methods for determining the optimal locations of the PSS. These two methods are based on Total Modified Coupling Factors (TMC) and optimization by Simulated Annealing (SA). The TMC is a measure of the damping influence …

Optimal Allocation of STATCOMs and Wind-Based Distributed Generators using a Stochastic Mathematical Program
… and power generation revenues. The Canadian 41-bus network with loads following the IEEE-RTS generic load model is used to test and validate the proposed planning approach. The achieved results demonstrate the effectiveness of such a planning approach in the allocation of STATCOMs and W-DGs. The …

Mitigating road work disruptions on bus service : a framework for passenger impact evaluation
… disrupting the operations on London's TfL bus network, increasing running times, running time variability, and headways. Operators manage disruptions by short-turning more often, making passengers have longer and less reliable journeys. Mitigation strategies are put in place to limit the …
