Dedicated Short Range Communication
- The DSRC Transportation Information System facilitates a high-tech transportation environment that is more accurate and more intelligent
- So far, the transportation information systems have had adopted the one-way communication with image/loop detectors to collect data, which put inevitable limitation on the reliability and the usability of the data. The DSRC Transportation Information System, however, can collect accurate data through hi-pass terminals installed on vehicles, and deliver interactive, diverse content services through the two-way communication, laying the groundwork for a high-tech transportation environment.
- DSRC
- Powered by roadside equipment capable of short-range two way communication, the DSRC collects and processes the data delivered from hi-pass terminals installed on running vehicles, and then provides the resulting information to road users.
- DSRC Features
- - Freeway/arterial road transportation information VMS
- - Bus Information System (BIS)
- - In-vehicle display of real-time transportation information (A high-pass terminal providing transportation information)
- - Provides reliable real-time road information using various IT devices
- - Provides specialized transportation information for each section
