Quantifying and Visualizing City Truck Route Network Efficiency Using a Virtual Testbed Overview Cities like NYC and Seattle need to deal with significant growth of urban deliveries as a result of increasing e-commerce compounded by increased stay-at-home behavior due to COVID-19. Even with the production of vaccines and a return to “normality” in the next…
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…
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…
An Artificial Intelligence Platform for Network-wide Congestion Detection and Prediction Using Multi-source Data Overview With the rapid growth of urban populations, traffic problems are getting worse in terms of increased traffic congestion and lengthened delays. Urban traffic congestion has become a critical problem that not only affects the people’s daily lives, but also restricts the…
Integrative Vehicle Infrastructure Traffic System (iVITS) Control in Connected Cities Overview This project will develop network-wide iVITS, leveraging team members’ current research on local and regional iVITS models and algorithms. Connected vehicle (CV) technology is taking shape with the government mandating the inclusion of vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (IVI) equipment such as the DSRC technology,…
