The streetcars run in the heart of downtown. They are subject to unstable operating conditions caused by traffic congestion, basketball games, and obstructed right-of-way. These perturbations make the Atlanta Streetcar prone to streetcar-bunching, which causes undue passenger wait and crowding. We have developped a real-time dispatching method that considers every streetcar on the route to dispatch them with even headways, while maintaining a high frequency of service.

Exergames -- video games played by engaging in physical activity -- could help older adults become more physically active. However, most exergames on the market are not developed with consideration of older adult users' physical and cognitive abilities. Our current study is evaluating the usability of commercially available exergames for this population by testing two exergames for Microsoft Xbox 360 with Kinect with participants aged 60 to 79. These findings will be leveraged to develop guidelines for designing a tutorial to teach older adults to use exergames.

In the last few years, there has been tremendous growth in the prevalence and widespread use of smart and ubiquitous technologies. These technologies include the use of smartphones, smartwatches and wearables, and smart devices. While these devices have a variety of benefits, they come at the cost of using our data for number of purposes that is not transparent to an average user. This project aims to understand how people perceive regarding privacy concerns with respect to their health data being collected and used by third party entities.
