What do Next-Generation transit technologies look like?

A future of transportation consisting of driverless cars and flying taxis is still distant. However, these next-gen transit technologies encompass a spectrum of innovations powered by IoT, artificial intelligence, and advanced data analytics already in use. These technologies are redefining the way people move within urban environments by introducing:

1. Delivery drones for last-mile delivery and intra-city transport. Either controlled remotely or autonomously with the help of artificial intelligence, these rechargeable flying robots navigate routes and drop-off points using GPS, sensors and computer vision systems. They are already being used by Amazon Prime Air and Zipline – the world’s largest autonomous delivery system.
