JAIPUR: Rajasthan will be the first state in the country where global positioning system (GPS) would be installed in around 1,000 buses of the state-owned Rajasthan State Roadways Corporation (RSRTC). The installation process would begin from Tuesday onwards. This system will not only enable the authorities to keep a track on the long-distance buses but will also facilitate them to put a check on things like theft of diesel which has been a big concern since it was rampant with the RSRTC buses.
