Public transport is the main way people travel in cities. However, due to traffic congestion, bus journeys can be unpredictable and frustrating. A trip that should take 30 minutes can stretch to over an hour during peak hours, leading to wasted time and stress. This has caused many people to switch from public transport to driving their own cars.
In Hong Kong, 89% of people use buses, while in the UK and France, the rate is between 76% and 80%. These numbers are much higher than in some domestic cities, highlighting a growing contradiction between public transport and private car usage. On one hand, drivers avoid buses because of delays caused by traffic. On the other hand, more private cars lead to even worse congestion, creating a cycle that's hard to break. The root cause remains traffic jams.
To break this cycle, two approaches are needed: encouraging private car owners to use buses and improving the efficiency of public transport services.
A key part of this solution lies in smart infrastructure. According to Qu Guoqing, General Manager of Qingdao Jiaoyun Warm Bus Company, smart buses and integrated traffic systems are the foundation of modern public transport. In Singapore, for example, transportation resources are managed through a centralized system that uses big data to control signals, manage traffic flow, and optimize bus routes. By collecting data from traffic lights, buses, and even private vehicles, cities can make real-time decisions to reduce congestion.
"Singapore has proven it's possible," said Qu. "With a network that connects all traffic information to the cloud, we can calculate and adjust signals dynamically. This helps keep traffic flowing smoothly."
At the hardware level, intelligent technology is also making a difference. Qingdao’s warm bus company has been upgrading its fleet with smart features like data transmission, voice communication, and video monitoring. This allows for better scheduling and faster response times. Instead of relying on phone calls, dispatchers now send commands via a computer, ensuring buses start on time and follow optimized routes.
In the high-tech zone, pilot projects for autonomous buses have begun, reducing labor costs and increasing accuracy. These efforts show how technology can transform public transport into a more efficient and reliable option.
Urban planning also plays a crucial role. In Qingdao’s high-tech zone, traffic priorities are embedded into city design. Wide roads, reserved bus lanes, and dedicated hubs are being developed to support public transport. A 40-mu transportation hub is already under construction, aiming to become a central transfer point for all types of vehicles. This model avoids the problems seen in older parts of the city, where bus lines often overlap and create inefficiencies.
Qu Guoqing emphasized that the goal is to build a "smart city" where public transport is prioritized in every aspect—signals, road rights, policies, and planning. The high-tech zone serves as a blueprint for future development, ensuring that new areas are designed with traffic efficiency in mind.
By combining smart technology, improved infrastructure, and forward-thinking urban planning, cities can encourage more people to choose public transport, ultimately reducing congestion and improving quality of life.
