There are privacy issues that might arise as a result of certain traffic software applications collection and usage of personally identifiable information such as location data. The next type of classifier is called the generative classifier. The width of the road and the volume of traffic on it determine the number of lanes that are present on the road. The WCA also required less computational time than the HS and Jaya algorithms. The optical flow approach is very effective in locating and evaluating moving objects [, One of the most important and active fields of research in the science of CV is multi-object tracking.
