ITS has evolved into a multidisciplinary conjunctive area of work because of its limitless possibilities, and many companies around the world have created solutions to meet the need for ITS applications.
Fremont, CA: With the idea of smart cities transforming cities into digital communities and making citizens' lives easier in every way, Intelligent Transportation System (ITS) becomes the most crucial component of all. Mobility is a significant concern in every area, and leveraging people with an ITS can save them time while also making the city smarter. ITS aims to improve 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 Traffic Management Center (TMC) is an essential component of ITS. It is primarily a transportation authority-managed technical infrastructure. All data is collected and processed here for future operations and real-time traffic control management, and information about local transportation vehicles.
The TMC's well-organized and proficient operations rely on automated data collection with precise location information, processing that data to produce accurate information, and then transmitting that information back to travelers.
Data Collection: Strategic preparation necessitates accurate, detailed, 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. 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 vast volumes of data for later review.
Data Transmission: This part of ITS consists of sending collected data from the field to TMC and then sending back that analyzed 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 networking and infrared connections are two other means of communication.
Data Analysis: TMC processes the data that has been obtained 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 advanced tools. After that, the data is manipulated and pooled in preparation for a review. This mended collective data is further analyzed to simulate traffic scenarios that can be used to provide relevant 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 details such as travel time, travel speed, delay, road incidents, route changes, diversions, and work zone conditions, among other things. Variable message signs, highway warning radio, internet, SMS, and automated mobile phones are all used to deliver this information.
