TY - JOUR PY - 1979// TI - Development of freeway incident-detection algorithms by using pattern-recognition techniques JO - Transportation research record A1 - Tsai, J. A1 - Case, E. R. SP - 113 EP - 116 VL - 722 IS - N2 - Two incident-detection experiments were conducted on the Queen Elizabeth Way Freeway Surveillance and Control System in Ontario. A pattern-recognition approach was applied to improve incident-detection algorithms. By considering the true- and false-incident-alarm identification process as pattern-recognition in nature, the maximum-likelihood decision principle was applied to develop an optimum incident-duration persistence test. The false-alarm rate fell from -.09 to 9.96 percent during a nine-month field test experiment. In the second experiment a two-layer committee-machine structure achieved an 85.7 percent detection rate on 28 samples of historical incident data.
