Data collection– Accurate, real-time, and extensive data collection is required for proper strategic planning. So, data is collected through hardware devices like Automatic Vehicle Identifiers, GPS-based automatic vehicle locators, cameras, etc.
The hardware device primarily records information like traffic count, travel speed and time, instances of delays, breakdowns, etc. The hardware devices are connected to the server which helps to collect a large number of data and store it in a data collection center that can be used for further study.
Data transmission– Swift and real-time information is the key to the efficiency of ITS. This feature helps in faster data transmission between the field and traffic management center.
Traffic-related announcements are conveyed to travelers via the internet, SMS, short-range communications (DSRC) using radio and continuous air interface, or Long and medium-range (CAILM) utilizing cellular connectivity and infra-red links.
