%X Real-time measurement of vehicle queue parameters is required in many traffic situations.This paper achieved a complete vehicle queue length measurement system,consisted of vehicle queue detection and queue length measurement.It exploited different processing methods at daytime and nighttime,and used a KNN classification to switch detection methods between daytime and nighttime.At daytime,the queue detection algorithm consisted of vehicle motion detection and vehicle presence detection,and used a profile co...
