Car Networking Technology: A New Era in Intelligent Transportation

The Genesis of Intelligent Transportation in Nanjing

Nanjing began its journey into intelligent transportation over ten years ago, becoming a trailblazer with the introduction of traffic light countdown displays at intersections. These early efforts laid the groundwork for more sophisticated systems that could collect and analyze traffic data in real-time.

Early Innovations

• Traffic Light Countdown Displays: These were among the first in the country, helping drivers anticipate signal changes and improve traffic flow.
• Coil Sensors: Installed in various sections, these sensors collected traffic data but were limited by the lack of a unified information platform.

The Role of Ran Bin and His Team

More than a year ago, Ran Bin arrived in Nanjing to lead the Southeast of Things Traffic Applied Research Centre. His vision was to create a more integrated and responsive traffic management system.

Real-Time Traffic Information

Ran Bin explained that traditional methods of disseminating traffic information, such as radio and television, suffer from delays. Electronic signs on major roads like Nanjing Zhongshan East Road provide real-time updates but are limited in scope.

• Mobile Integration: The new system aims to bring these updates directly to drivers' smartphones. Using a mobile app, drivers can see real-time traffic conditions and choose the best routes accordingly.
• Traffic Information Platform: Developed for Shanghai, this platform uses a combination of GPS, HD cameras, microwave radar, and mobile data to provide a comprehensive traffic overview.

Building a New Intelligent Transportation System

Ran Bin's team, in collaboration with the University of Wisconsin-Madison and Southeast University, has developed a mobile location technology that automatically sends traffic data to a central platform. This data is then processed using cloud computing to provide real-time traffic updates.

Key Features

• Mobile Location Technology: Each phone sends its location data to a central platform, helping to map out traffic conditions.
• Cloud Computing: This technology processes the data to provide real-time traffic updates, making the system highly efficient.

The Future of Intelligent Transportation in Nanjing

Ran Bin's entrepreneurial vision includes the establishment of Nanjing Madison Information Technology Co., Ltd., which aims to build an integrated transportation information platform for the city. The company plans to offer mobile traffic broadcast services and aims to go public within five years.

Goals and Objectives

• Integrated Transportation Platform: A unified system that collects and analyzes traffic data from various sources.
• Mobile Traffic Broadcast Services: Real-time traffic updates delivered directly to drivers' smartphones.
• Public Listing: The company aims to be listed on the stock exchange within five years.

Interesting Stats and Data

• Traffic Congestion Costs: According to the INRIX Global Traffic Scorecard, traffic congestion cost the U.S. economy nearly $87 billion in 2018 alone source.
• Smart City Investments: The global smart city market is expected to grow from $410.8 billion in 2020 to $820.7 billion by 2025, at a CAGR of 14.8% source.

Conclusion

Nanjing's journey into intelligent transportation is a testament to the power of innovation and collaboration. With the efforts of Ran Bin and his team, the city is set to become a model for smart traffic management, offering a glimpse into the future of urban mobility.
