The Rise of Driverless Transit: A Visions for the Future
The vision of driverless transit is not a far-fetched idea, and companies like Imagry are taking steps towards making it a reality. The technology behind autonomous buses is based on the same principles as other autonomous vehicles, using computer systems to drive the vehicle instead of a human being. This provides a sustainable transportation solution with reduced human errors, improved safety, and enhanced passenger experience.
The Challenges of HD Maps
High-definition maps, while beneficial for navigation, pose a significant challenge for autonomous vehicle operation on public roads. The accuracy of the maps required is around five centimeters, which can be challenging to achieve. Moreover, HD maps require large computer storage and the ability to send large quantities of data quickly, making them expensive to create and update.
- Large storage requirements: HD maps require significant amounts of storage to hold the data.
- Complexity of update: To ensure the maps remain accurate, they need to be updated regularly, which adds to their complexity.
- Cybersecurity concerns: The reliance on HD maps exposes autonomous vehicles to cybersecurity threats, which can compromise the safety of passengers.
A Alternative Approach: Mapless Autonomous Driving
Imagry is developing a mapless driving system that allows for greater flexibility and adaptability. This approach enables autonomous vehicles to operate better in urban environments where road conditions can change quickly. Mapless systems do not require HD maps, making them more feasible for deployment on public roads.
Overcoming Technical Barriers: Advancements in Computing Power}
Until recently, it was impossible to equip moving vehicles with computers capable of running AI systems. However, recent advancements in computing power have changed this scenario. The new chips available in the market have made it possible for autonomous vehicle research to move forward. As a result, various autonomous features, such as parallel parking assist and traffic jam assist, are becoming increasingly available.
Developing Autonomous Buses: Software-defined Vehicles
The development of autonomous buses requires a drive system compatible with computer systems. Sending turning directions and steering the bus directly becomes easier for AI systems. Software-defined vehicles, also known as computers on wheels, are the first step towards truly driverless vehicles, including buses.
Regulations and Safety: Ensuring Autonomy
Government regulations play a significant role in deploying autonomous vehicles. Currently, most autonomous vehicles on the road are level three vehicles that still require a driver to take over if necessary. Level four autonomous vehicles are completely driverless and are expected to make their debut soon. Imagry is working towards deploying level four buses on city streets overseas.
Testing and Deployment: Rigorous Evaluation
The final test for autonomous buses involves conducting rigorous tests in controlled facilities. The tests simulate various scenarios, including pedestrian crossings and traffic congestion. The buses also undergo cybersecurity testing to ensure they can withstand potential threats. Imagry is selected locations that have fewer regulations regarding autonomous vehicles, allowing for easier testing and deployment.
The Selection of Deployment Locations: European and Beyond
Imagry is working on autonomous bus projects in Israel, Japan, and Portugal, with proposals being considered in several other European countries. The selection of deployment locations is crucial, considering the local laws and regulations regarding autonomous vehicles.
The Final Steps: Testing and Certification
The final proof of autonomous bus capability involves conducting 100,000 kilometers of continuous operation without human intervention or incident. This milestone is expected to be achieved by September 2025. When this occurs, the safety driver can be removed, marking a new era in public transportation.
Example: Japan’s Testing Ground
Japan has established a testing ground for autonomous vehicles, which has contributed significantly to the development of autonomous bus technology. This ground has enabled various companies, including Imagry, to test their autonomous buses on a large scale.
Example: Germany’s Regulation Framework
Germany has established a strict regulation framework for autonomous vehicles, which aims to ensure safety and security. This framework provides a clear guideline for testing and deployment of autonomous buses, aligning with Imagry’s goals and objectives.
Example: The Importance of Cybersecurity
Cybersecurity plays a critical role in ensuring the safety of autonomous buses. Imagry’s mapless driving system, for instance, does not require HD maps, reducing the risk of cyber threats.
Conclusion
The development of autonomous buses is a pioneering endeavor in public transportation, offering a sustainable and efficient solution for reducing traffic congestion and improving passenger experience. With significant advancements in technology, software-defined vehicles, and regulation, the deployment of autonomous buses is becoming a reality. As we move forward, it is essential to consider the challenges and opportunities presented by this innovative technology to ensure a seamless integration into our daily lives.
