Abstract: An automatic speech recognition system recognizes user changes to dictated text and infers whether such changes result from the user changing his/her mind, or whether such changes are a result of a recognition error. If a recognition error is detected, the system uses the type of user correction to modify itself to reduce the chance that such recognition error will occur again. Accordingly, the system and methods provide for significant speech recognition learning with little or no additional user interaction.

Abstract: A method and system are provided for determining travel time through intersections by assigning an initial position for a virtual probe in the intersection and updating the position and velocity for the virtual probe such that the position and velocity of the virtual probe are determined multiple times from a time when the virtual probe is at an initial position until the time when the updated position of the virtual probe is past a stop line at the intersection. Updating the position and velocity of the virtual probe involves retrieving vehicle detection data and traffic control signal data to determine a distance from the virtual probe to the closer of a stop line and a vehicle in a queue in front of the virtual probe. The length of the queue is determined using the intersection of two shockwaves.
