Government is planning to implement GPS based tolling. This will increase the revenue and will also increase the toll that affects public (High toll tax will be charged). How this system work ? cameras and scanners will be installed at the starting and end of the highways. These scanner will scan the HSRP of the car and send this to the VAHAN PORTAL of Road and Transport ministry and GPS will trace the location of the car according to that toll will be directly deducted from the account. Challenges in this system. 1 - Highways are not properly barricaded due to which lot of people will travel free on highways. 2 - GPS should be installed in every cars. 3 - This system requires very huge investment. Many countries like America , Australia , Canada and many more implements this system but did not succeed so they removed it.
