Data-Driven Bike-Share Ridership Prediction and Network Optimization
Shared micro-mobility systems, particularly station-based bike-sharing networks, have become key components of urban transportation, yet their planning remain challenged by spatial and technological complexities. This dissertation develops integrated models for ridership prediction, station …

Design of a kickstand-integrated bicycle lock for a bike share program
… Social Computing group as part of a peer-to-peer bike-share program currently in development. Connecting to the rear axle, the system consists of two modules, each constructed of many planar parts cut on the waterjet from aluminum. The first of these is a lock, which uses a servo-driven double …

Modeling demand of bike share system using built environment attributes in the city of Buenos Aires, Argentina
Increasing the share of trips done by bike has become an objective of cities worldwide. At the individual level, biking is associated with better physical and mental health. At the city level, biking contributes to alleviate traffic congestion, reduce commuting times and improve air quality. This …

Learning with structured decision constraints
… is to estimate the primary demand for a bike-share service using censored data of commuters' trips. We model commuter arrivals with a Poisson process and characterize their trip preferences with a probability mass function (PMF) over rankings of origin-destination pairs. Estimating the …

Design for low-power high-density helmet dispensing and collection systems for urban environments
… a machine to dispense and collect helmets for bike-share programs such as Boston's Hubway. Design of the machine was guided under several constraints including size and power for tight integration with existing bikeshare stations. The machine itself is divided into subsystems, including …

Smart City Energy Efficient Multi-Modal Transportation Modeling and Route Planning
… We develop different models to predict bike travel times for use in bike share systems (BSSs) using random forest (RF), least square boosting (LSBoost), and artificial neural network (ANN) techniques. We also use cycling Global Positioning System (GPS) data collected from 10 people (3 …
