Mobility is a significant concern in every area, and leveraging people with an Intelligent Transportation System (ITS) will save them time while also making the city smarter. ITS aims to boost traffic quality by reducing traffic congestion. It provides users with advanced traffic information, local convenience information, real-time running information, seat availability, and other features that help commuters save time while also improving their safety and comfort.
The use of ITS is now commonly recognized and practiced in many countries. It can be used for more than just traffic congestion management and information; it can also enhance road safety and infrastructure utilization.
How Intelligent Transport System works?
Traffic Management Centre (TMC) is the integral unit of ITS. It is primarily a technical system controlled by the transportation authority. All information is gathered and processed here for future operations and real-time traffic control management, as well as information about local transportation vehicles.
The Traffic Management Centre's well-organized and proficient operations rely on automated data collection with accurate location information instead of analyzing it to produce correct information and then transmit it back to travelers. Let's take a closer look at the process as a whole.
Data collection: Strategic preparation necessitates accurate, comprehensive, and timely data collection as well as real-time monitoring. As a result, data is collected using various hardware devices that serve as the foundation for future ITS functions. Automatic Vehicle Identifiers, GPS-based automatic vehicle locators, sensors, and cameras are examples of these devices. The hardware primarily records information such as traffic counts, surveillance, travel speed and time, location, vehicle weight, and delays, among other things. These hardware devices are linked to servers, usually found at data collection centers, and store large amounts of data for future evaluation.
Data Transmission: Fast and real-time information communication is vital to proficiency in ITS implementation, so this part of ITS comprises of the transmission of compiled data from the field to TMC and then sending back that assessed information from TMC to travelers. Travelers are informed of traffic-related announcements via the internet, SMS, or vehicle onboard units. Dedicated short-range communications (DSRC) using radio and Continuous Air Interface Long and Medium Range (CAILM) using cellular connectivity and infrared links are two other communication methods.
Data Analysis: TMC processes the data that has been collected and received in several ways. Error rectification, data cleaning, data synthesis, and adaptive logical analysis are the steps involved. Data inconsistencies are detected and corrected using specialized software. After that, the data is manipulated and pooled in preparation for analysis. This mended collective data is further analyzed to predict traffic situations that can be used to provide useful information to users.
Traveler Information: Travel Advisory Systems (TAS) are used to keep travelers up to date on transportation updates. The system provides real-time information such as travel time, travel speed, delay, road accidents, route changes, diversions, and work zone conditions, among other things. Variable message signs, highway advisory radio, internet, SMS, and automated cell phones are all used to deliver this information.
