Operators of highway management centers provide round the clock monitoring
of highway traffic, traveller information, incident management, and traffic
management. Safety critical decisions are made by gathering information
from a heteregenous systems providing radio communications, weather predictions,
sensor and video data, etc. We are exploring how advanced user interfaces
and information visualization can improve operators' situation awareness
and decision making ability in routine and emergency situations.
We are providing user interface design and evaluation guidance
to the State of Maryland State Highway Admistration during their redesign
of CHART, the state highway
management information system.
One of our research focus has been the design and development of a simulation-based
learning environment aimed at providing students and operators a better
understanding of the effect of incidents on highway and arterial delays.
We used an development environment called SimPLE
developed by our colleagues at the University of Maryland.
Another exploration is the comparisons of the ways to present realtime traffic information on public websites.
