Introduce On-board Units (OBU) at vehicle registrations and properly maintained roadside parking slots. Track the slot and time period using OBUs to charge the vehicles. Introduce E- payment system to pay charges and fines using a mobile device. Once vehicle user parks and leaves, he has to indicate using the mobile app, if not the vehicle with the OBU will be fined. Introduce a season ticketing system for regular vehicle parking users.
This will reduce traffic congestion by proper roadside parking and less number of vehicles on the road due to charged parking.
