Mitigating emissions and energy consumption for urban transportation networks : simulation-based signal control strategies
(Massachusetts Institute of Technology, 2013)
Microscopic urban traffic simulators embed the most detailed traveler behavior and network supply models. They represent individual vehicles and can therefore account for vehicle-specific technologies. These simulators can ...
Making data matter : the role of information design and process in applying automated data to improve transit service
(Massachusetts Institute of Technology, 2013)
As public transit agencies install new technology systems they are gaining increasing amounts of data. This data has the potential to change how they operate by generating better information for decision-making. Deriving ...
Linear elastic fracture mechanics in anisotropic solids : application to fluid-driven crack propagation
(Massachusetts Institute of Technology, 2013)
Fracture mechanics is a field of continuum mechanics with the objective to predict how cracks initiate and propagate in solids. It has a wide domain of application. While aerospace engineers want to make sure a defect in ...
Classification of London's public transport users using smart card data
(Massachusetts Institute of Technology, 2013)
Understanding transit users in terms of their travel patterns can support the planning and design of better services. User classification can improve market research through more targeted access to groups of interest. It ...
An analysis of area type and the availability of alternative transportation services on subjective well-being : are people happiest in cities?
(Massachusetts Institute of Technology, 2013)
This study is a comprehensive analysis of how rural, suburban, and urban areas compare in terms of the subjective well-being (SWB) of their residents and how the availability of transportation services affects SWB. Because ...
Urban transportation networks : analytical modeling of spatial dependencies and calibration techniques for stochastic traffic simulators
(Massachusetts Institute of Technology, 2013)
Exact numerical evaluation of the stationary joint queue-length distribution of a Markovian finite capacity network with arbitrary size and topology can be obtained numerically. Nonetheless, the main challenge to such an ...
Effects of droplet size on intrusion of sub-surface oil spills
(Massachusetts Institute of Technology, 2013)
This thesis explores the effects of droplet size on droplet intrusion in sub-surface oil spills. Laboratory experiments were performed where glass beads of various sizes, which serve to simulate oil droplets in deepsea oil ...
ChangiNOW : a mobile application for efficient taxi allocation at airports
(Massachusetts Institute of Technology, 2013)
The important role that taxis play in bringing passengers from an airport terminal to their final destination is often overlooked in airport operations and design. Due to varying flight arrival patterns at different ...
Interoperable software for parametric structural analysis and optimization
(Massachusetts Institute of Technology, 2013)
The advent of building information modeling in the structural engineering profession has brought forth new challenges to the traditional methods of design and analysis. The need for faster, more robust analyses to mitigate ...
Stability of elastic grid shells
(Massachusetts Institute of Technology, 2013)
The elastic grid shell is a solution that combines double curvature and ease of mounting. This structural system, based on the deformation of an initially at grid without shear stiffness was invented more than fifty years ...
