The focus of the Determination of Controller Issued Taxi Commands (DCITC) Program is to evaluate technology that could be used to proactively determine the taxi route that an aircraft should or is likely to follow on the airport surface. The technological approaches being investigated include speech recognition (SR) and contextual inference (CI). The primary motivation for the concept is the expectation that effective and automatic prediction and/or determination of taxi routes could eventually provide the basis for a situational awareness or safety logic enhancement for use by air traffic controllers. Runway incursions are still occurring at significant rates. The reduction of runway incursions has been identified as one of the most important aviation safety initiatives by the Federal Aviation Administration (FAA), the National Transportation Safety Board (NTSB), and Congress. Many improvements in training, procedures, and technology have been introduced, but there are still hundreds of incursions each year. Although it seems obvious that earlier detection of taxiing errors would help to prevent runway incursions, there is no system in place to automatically detect such errors.
