Los Angeles cuts downtown congestion with smart parking

Los Angeles is reducing congestion with a demand-based parking system that adjusts prices based on real time occupancy data, in order to evenly distribute cars across downtown bays. Sensors record when parking spots are occupied, and transmit the information to a central computer system that recommends price adjustments. Drivers are notified of available slots via mobile apps that let them reserve spaces in advance. The system aims to keep bays unoccupied between 10% and 30% of the time.
