Spectrum of Public Transit Operations: From Fixed Route to Microtransit Overview With advances in emerging technologies, options for operating public transit services have broadened from conventional fixed route service through semi-flexible service to on-demand microtransit. Guidelines for deciding between these services remain limited. This study serves two primary objectives. The first is to provide an…
Traffic Signal Optimization and Coordination in Connected Cities Overview Connected vehicles in smart cities, including vehicle to vehicle (V2V), vehicle to infrastructure (V2I), and vehicle to anything (V2X) communications, can provide more opportunities and impose more challenges for urban traffic signal control. This research aims to explore the basic research on developing signal control and…
Understanding Mobility Patterns and Decision-making Using an Integrated, Multi-modal Sensing Platform in a Quantified Community Overview City governments all over the world face challenges understanding mobility patterns within dense urban environments at high spatial and temporal resolution. While such measures are important to provide insights into the functional patterns of a city, novel quantitative methods,…
Integrative Vehicle-Traffic Control in Connected/Automated Cities Overview The Importance of Integrative Vehicle-Traffic Control In the United States, gasoline consumption by the transportation sector in 2016 was about 143.37 billion gallons, a daily average of about 9.33 million barrels. At the same time, traffic congestion on urban roads causes extra fuel consumption as well as additional…
Automated Truck Lanes in Urban Area for Through and Cross Border Traffic Overview Automated Vehicles and Highway Capacity In the current driving system, a significant amount of lateral and longitudinal space between vehicles is required for safety and psychological reasons. The longitudinal separation increases as the speed of the vehicle increases, and larger spaces are…
Dual Rebalancing Strategies for Electric Vehicle Carsharing Operations Overview Challenges in Vehicle Rebalancing for Car Sharing Services Car sharing is a smart mobility paradigm where a population of users share usage of the vehicles. This can be done through booking vehicles for specific time slots from specific locations that are returned to the same locations…
Deliverables The main deliverable for this project was a smartphone navigation app that addresses the specific mobility needs and priorities of seniors, improving their ability to travel around their cities. After the prototype was developed, the researchers recruited seniors to test the app for a few weeks, and then gathered their feedback. In order to…
Integrated Analytics and Visualization for Multi-Modality Transportation Data Overview This research project aimed to develop a data-driven approach for modeling cities, with a focus on pedestrian dynamics, which play a fundamental role in urban planning. It focused on detecting and counting objects such as pedestrians, cars, and bicycles in visual data sources that can provide…
