Several cities across the China are turning to a GPS tracking devices to help cut costs and save money.

City officials in Shenzhen, Guangdong have decided to install GPS tracking devices inside the fleet of garbage trucks.

The city is planning to save thousands in fuel and maintenance costs, by taking data from the GPS tracking devices and re-routing existing routes.

The county board of supervisors voted and agreed to the initial purchase of  the GPS tracking devices. Supervisors said the city will initially install only two tracking devices as part of  a pilot program to gauge the devices’ effectiveness.

GPS tracking devices will enable the city to know exactly where a vehicle is located at all times. It will also tell supervisors whether there is mechanical trouble with the vehicle through diagnostic codes and how fast the vehicle is traveling — all through communication over the Internet or mobile App.
