Bickel, Peter J., Chen, Chao, Kwon, Jaimyoung, Rice, John, Van Zwet, Erik, Varaiya, Pravin
A traffic performance measurement system, PeMS, currently functions as a statewide repository for traffic data gathered by thousands of automatic sensors. It has integrated data collection,...

An algorithm for real time estimation of truck traffic in multi-lane freeway is proposed. The algorithm uses data from single loop detectors-the most widely installed surveillance technology for...
Traffic Flow on a Freeway Network (2001)
Peter Bickel, Chao Chen, Jaimyoung Kwon, John Rice, Erik Van Zwet
This paper gives an overview of some of our activities, focusing on gathering statistics on traffic flow over the network of freeways in Los Angeles and on the prediction of travel times over this...
Day-to-Day Travel Time Trends and Travel Time Prediction from Loop Detector Data (2001)
Jaimyoung Kwon, Benjamin Coifman, Peter Bickel
This paper presents an approach to estimate future travel times on a freeway using flow and occupancy data from single loop detectors and historical travel time information. The work uses linear...
A New Methodology for Evaluating Incident Detection Algorithms (2000)
Petty, Karl, Bickel, Peter J., Kwon, Jaimyoung, Ostland, Michael, Rice, John
We present a novel, off-line approach for evaluating incident detection algorithms. Previous evaluations have focused on determining the detection rate versus false alarm rate curve -- a process...
Modeling Freeway Traffic with Coupled HMMs (2000)
We consider the problem of modeling loop detector data collected from freeways. The data, which is a vector time-series, contains the speed of vehicles, averaged over a 30 second sampling window, at...

A New Methodology for Evaluating Incident Detection Algorithms (1999)
Karl F. Petty, Peter J. Bickel, Jaimyoung Kwon, Michael Ostl, John Rice
We present a novel, off-line approach for evaluating incident detection algorithms. Previous evaluations have focused on determining the detection rate versus false alarm rate curve --- a process...
Local feature frequency profile: A method to measure structural similarity in proteins
Choi, In-Geol, Kwon, Jaimyoung, Kim, Sung-Hou
Measures of structural similarity between known protein structures provide an objective basis for classifying protein folds and for revealing a global view of the protein structure universe. Here, we...
