Vehicle counting system and vehicle speed measurement based on video processing is one of the systems that utilize digital image processing system as a detector of a moving object such as a vehicle to do the counting and measurement speed. This system is an early stage in the development of Intelligent Transportation System. The methods are used in this system are background subtraction with Gaussian Mixture Model (GMM) algorithm and blob detection. Background subtraction method used because it is a method that can separate foreground and background smoothly and adaptive to the condition of the frame. The blob detection method provide the coordinates in the form of centroid so it will show the movement of the object vehicle. Speed calibration testing parameters obtained with the use of a speed gun. The accuracy of vehicle counting obtained by the method of evaluation of the system by comparing the real situation with the results of the system. The value of the vehicle speed measurement uncertainty obtained using standard deviation calculations and the combined uncertainty. Vehicle counting accuracy on the first morning conditions obtained 75.69%. On the second morning of the conditions obtained accuracy of 75.30%. Vehicle counting accuracy on the first afternoon obtained 80.84% and for the second afternoon obtained 90.50%. Accuracy of counting vehicles in the late afternoon obtained 85.31%. The value of the uncertainty around the condition are at a value of ± 3 km/h.
