SELF-DRIVING
How can autonomous buses revolutionise city transportation? Jake Holmes fi nds out
This technology brings the reality of driverless buses a step closer
s technology advances and labour markets shorten, autonomous driving solutions for
public transportation are becoming inevitable. Eran Ofi r, CEO of autonomous driving company Imagry, sat down with International Transport Manufacturer to explain his company’s existing self-driving technologies, as well as the future of autonomous
driving and how regulators can best help introduce these new systems.
HOW DO THEY WORK? External 3D mapping is a method of capturing locations to provide a digital representation of the world. Although this technology has been used in autonomous driving before, it is not used to drive Imagry’s autonomous buses. Instead, a network of cameras

feed information to the main computer allowing it to create a 3D map. Each camera is tasked with detecting traff ic lights, vehicles, pedestrians and any other road-related items. “We do not use those external HD
maps that are provided to vehicles, but instead those that are created on the go,” says Ofi r. “The entire system is built out of neural networks and is AI end-to-end. We get the video feed from eight cameras into an array of neural networks where each neural network is responsible for object detection and classifi cation for a diff erent type of object. One is looking at traff ic lights, one at pedestrians, and then we build in real time a three- dimensional map that represents everything in the surrounding of the vehicle up to 300m and 360°.” Imagry’s autonomous buses do
not use rule-based coding, which is when computers are given specifi c rules to react to situations, similar to a decision fl owchart. Instead, a black box is fed with information from the neural network which learns
