Travel time estimates, it will use the information the average speed (Average Speed) on the way as a main data auditing flow rate at that time, with the actual data that reflect the speed of traffic conditions at that time or not. All data from the device is sent back to the control center to calculate and display the labels to the VMS or other sofwae. To calculate the average speed on the line is the velocity from the retina Image Processing speed from Dhaka, used to calculate the average speed of each period (Road Section), and then take the average velocity in each period to calculate to estimate the duration of the travel range distances by the accuracy depends on the frequency of observation points, including the accuracy of the data, the average speed obtained from the device.
