High-Resolution Traffic Sensing with Autonomous Vehicles
Wei Ma, Sean Qian
The last decades have witnessed the breakthrough of autonomous vehicles (AVs), and the perception capabilities of AVs have been dramatically improved. Various sensors installed on…
Measuring and reducing the disequilibrium levels of dynamic networks through ride-sourcing vehicle data
Wei Ma, Sean Qian
Transportation systems are being reshaped by ride-sourcing and shared mobility services in recent years. The transportation network companies (TNCs) have been collecting high-granu…
Estimating multi-class dynamic origin-destination demand through a forward-backward algorithm on computational graphs
Wei Ma, Xidong Pi, Sean Qian
Transportation networks are unprecedentedly complex with heterogeneous vehicular flow. Conventionally, vehicle classes are considered by vehicle classifications (such as standard p…
Understanding and predicting travel time with spatio-temporal features of network traffic flow, weather and incidents
Shuguan Yang, Sean Qian
Travel time on a route varies substantially by time of day and from day to day. It is critical to understand to what extent this variation is correlated with various factors, such…
A deep learning approach to real-time parking occupancy prediction in spatio-temporal networks incorporating multiple spatio-temporal data sources
Shuguan Yang, Wei Ma, Xidong Pi +1
A deep learning model is applied for predicting block-level parking occupancy in real time. The model leverages Graph-Convolutional Neural Networks (GCNN) to extract the spatial re…
