Chongqing - Green elements and big data are highlighted as two focuses driving the development of transportation in Chongqing, as revealed in the recently published 2022 Annual Report on Transportation Development in Chongqing's Central Urban Area.

Empowering precise traffic management with big data

While citizens may not yet be aware of the changes, big data studies the city's traffic flow and influences public transportation by providing administrators with recommendations for alternative routes and vehicle types.

For instance, data analysis revealed that the Dazhulin area in downtown Chongqing had a potential passenger flow of approximately 10,000 people without adequate bus routes. This flow was mainly concentrated in surrounding residential neighborhoods, commercial centers, docks, and parks. 

To address this, a new bus route, Route 1619, was formed to accommodate the demand by deploying a medium-sized bus.

Another similar situation occurred on Renmin Branch Road in Yuzhong District, where the narrow road width and vehicles had a limited turning radius. 

By utilizing big data calculations, administrators introduced Route 3209 with smaller buses. This adjustment reduced the average walking time for nearby passengers from seven-ten minutes to four minutes.

New Energy Driving Vehicle Growth

In 2022, among the newly added vehicles in the central urban area, 64% were new energy vehicles, totaling 171,000 vehicles, representing a year-on-year growth of 78.2%. 

Within the composition of new energy vehicles in the central urban area, private cars accounted for 60%, ride-hailing cars accounted for 23%, and logistics special vehicles, public buses, and other vehicle types accounted for the remaining 17%.

Simultaneously, citizens' travel patterns reflect environmentally friendly and low-carbon transportation trends. Statistics show that over half of the residents in the central urban area choose public transportation. This preference is closely related to the wider coverage of public transportation networks. 

According to transportation big data, in 2022, the population coverage within a 10-minute walk of rail stations in the central urban area reached 39%, an increase of 4% compared to the previous year.
