Nexar releases driver behavior maps to humanize robot drivers
Crowdsourced vision data collected from Nexar’s smart dash cams helps AVs stop, merge, turn and drive like humans, providing a safer driving experience.
TEL AVIV, Israel, August 30, 2022 /PRNewswire/ — Nexar, a leading AI-based computer vision company, today announced the release of its driver behavior mapping data. The driver behavior map provides an overview of different road segments, driver types, weather and road conditions. Nexar’s dash cams capture a wide range of crowd-sourced driving data about real-life human driving behavior, then aggregate and overlay it onto a high-definition basemap to be used for autonomous and assisted driving.
As local agents who have driven in an area know more than agents who have not, whether autonomous or human, AVs will use real-time data from Nexar to humanize driving by training in local driving culture and mapping crucial driving habits. AVs can use these maps to determine when to change lanes before a turn, how to slow down in turns, where virtual stop lines are, and more.
“A self-driving car that only drives according to a raw map would be an immediate danger due to its robotic driving style,” said Eran Chir, Co-founder and CEO of Nexar. “It’s not necessarily that humans drive better than robots, it’s that AVs need a lot of human data obtained by those who have passed through a particular area. Without even being aware of it, we take hundreds of decisions that adapt to local conditions, culture and comfort each time we drive.AVs need to synchronize with this behavior in order to provide the safest and most comfortable drive.
Nexar’s driver behavior map considers speed distribution, acceleration distribution, turn probability at intersections, lane change probability, and virtual crosswalks, among others. Providing a smooth and safe ride, behavior-trained AVs will better understand, measure, and compare safety-related behaviors (stop lines, school zones, etc.), as well as drive better based on road and traffic conditions. the visibility. Nexar’s maps will give AV vehicles human-like driving behavior, while benefiting from the safety advancements of a robot driver.
“Nexar is used by commercial and ordinary drivers, at all hours of the day, on different road segments and in all weather conditions,” Shir continued. “There is no more efficient or cost-effective way to collect this diverse set of human driving data that is such a crucial part of our journey to advancing a safe future for autonomous driving. With the right data, a AV running from Nexar’s driver behavior map will continue to become indistinguishable from a human-driven car in terms of driving flow.”
Cars equipped with Nexar’s smart dash cams travel more than 160 million miles per month, providing valuable driving data across the United States. By accessing a real-time record of how other vehicles travel on the same segment of road at different times of day, AVs can “see” what lies ahead and use a map that is constantly updated. Maps cover all 50 states.
Founded in 2015, Nexar’s mission is to achieve Vision Zero, making the world collision-free. Creating a network of smart, connected vehicles, Nexar uses dash cams to generate a new, high-quality understanding of the world – at street level. Resulting in a constantly updated library of 4 trillion images and videos, 200 million kilometers of footage are added every month. Aggregated, anonymized and paired with vision-based AI, this data is used to power a digital twin of the world. Nexar has developed a portfolio of vision-based data services and solutions for businesses across a multitude of industries, including OEMs, fleets, insurance, autonomous vehicles and the public sector.
