I. L4 Autonomous Driving Buses: The Vanguard of Future Transportation

L4 autonomous driving buses represent vehicles capable of achieving full autonomy in specific environments, requiring no human intervention.

Chengdu Hi-Tech Zone will establish an L4 autonomous driving bus demonstration scenario in the Xinchuan Innovation Science Park, offering intelligent and convenient public transportation solutions to park employees and citizens alike.

This demonstration route serves not only as a showcase of advanced technology but also as a foray into commercialization.

Through this initiative, Chengdu Hi-Tech Zone aims to expedite the verification and product iteration of cutting-edge unmanned technologies, including vehicle-road collaboration for autonomous buses.

II. The Technical Core: Synergy Between Vehicles, Roads, and Clouds

The essence of L4 autonomous driving buses lies in the seamless integration of vehicles, roads, and cloud systems.

In essence, it connects vehicles, roads, and cloud data via intelligent connected technology, enabling global optimization and collaborative perception.

Take Chengdu Hi-Tech Zone as an example; the city has deployed 486 sets of RSU (Roadside Units), over 1,900 sensing devices, and 68,000 5G base stations, covering 200 square kilometers of urban open roads.

These devices process sensing data in real-time through edge computing units (MEC) and transmit structured data to vehicles, providing ultra-horizon perception and blind spot perception support for autonomous driving.

The application of this technology not only enhances vehicles' autonomous driving capabilities but also optimizes urban traffic management.

For instance, more than 2,000 buses in Chengdu are equipped with C-V2X terminals, resulting in an 80% increase in the on-time rate of bus priority routes during peak hours.

III. Rapid Scenario Expansion: 20 Application Scenarios Touching Future Life

The 20 technological innovation application scenarios unveiled by Chengdu Hi-Tech Zone encompass four cutting-edge fields: artificial intelligence, intelligent robots, low-altitude economy, and unmanned driving.

These scenarios not only highlight Chengdu Hi-Tech Zone's pioneering position in technological innovation but also provide citizens with accessible smart living experiences.

1. Low-Altitude Economy: This includes scenarios such as the Public Security Bureau's low-altitude policing, which supports urban public security patrols, event security, search and rescue, and other police operations leveraging drone technology.

2. Artificial Intelligence: Scenarios like 'Digital Canteen', AI smart diagnosis and treatment, and IC PARK smart parking further expand the practical application of AI technology across multiple industries.

3. Intelligent Robots: For example, the Xinchuan Heart Robot Park will create intelligent delivery equipment service scenarios, optimizing route planning to enhance the smart experience and improve service quality.

4. Unmanned Driving: The L4 autonomous driving bus demonstration scenario provides intelligent and convenient public transportation for professional park employees and citizens.

IV. Policy Acceleration: Streamlining Approval Processes for Faster Commercialization

Chengdu Hi-Tech Zone is also at the forefront of policy support.

By establishing a two-level scenario innovation work mechanism at the city and district levels and integrating the 'Chengdu Market Scenario Innovation Promotion Center' within the Chengdu Private Economic Development Promotion Center, a new 'Scenario Innovation Department' has been formed, comprising a professional team dedicated to substantive office work.

Taking 'scenario innovation' as a breakthrough, it fosters a closed-loop ecosystem of 'demand driving technology, technology empowering industry'.

The new policy has also introduced a special working team mechanism, merging the road testing and demonstration application stages, and supporting mutual recognition of qualifications from other cities' testing stages, thereby halving the test time for enterprises to initiate high-level autonomous driving commercial operations.

V. Vision for the Future: How Chengdu Hi-Tech Zone Will Lead the Nation

Chengdu Hi-Tech Zone's 'vehicle-road-cloud integration' pilot area represents not only a technological breakthrough but also an innovative business model.

Over the next three years, Chengdu Hi-Tech Zone will designate a 1,200 square kilometer area encompassing five districts within the city as a pilot region, delving into the implementation of 'vehicle-road-cloud integration' technology and the large-scale application of intelligent connected vehicles, achieving interconnectivity between 'two stations (Chengdu Railway Station and Chengdu South Railway Station) and one airport (Chengdu Shuangliu International Airport)'.

The launch of the L4 autonomous driving bus demonstration scenario in Chengdu Hi-Tech Zone marks a significant step towards transitioning autonomous driving from the 'testing ground' to the 'main road'.

Through technological advancements, policy support, and scenario innovation, Chengdu Hi-Tech Zone is spearheading the development of the intelligent connected vehicle industry nationwide.

In summary, Unmanned Vehicles Coming (public account: Unmanned Vehicles Coming) believes that this press conference underscores Chengdu Hi-Tech Zone's commitment and efforts towards the integrated development of technological and industrial innovation. The introduction of the L4 autonomous driving bus demonstration scenario and various intelligent application scenarios fills us with anticipation for the future.
