Unraveling the Paradox: Beijing's Enclosed Spaces vs. Unending Traffic
The Enduring Legacy of Enclosed Spaces in Chinese Urban Design
The concept of enclosed spaces, or 'compounds,' deeply ingrained in Chinese culture, manifests significantly in urban landscapes, symbolizing both a sense of home and a distinct boundary. From the formidable Great Wall to the Forbidden City, and extending to contemporary institutional and residential complexes, these varied forms of enclosures profoundly segment China's urban fabric and its transportation arteries. Beijing, a prime example of a 'compound city,' faces severe traffic challenges due to countless such enclosures that result in sparse public road networks, numerous dead-end streets, and an overburdened main road system, making traffic jams an entrenched issue. The escalating conflict between these 'compound clusters' and urban traffic has reached a critical point, becoming an increasingly intense struggle.
Beijing's Unique Urban Layout: A Labyrinth of Walls and Roads
If one were to project the entire world onto a flat surface with sufficient clarity, an intriguing observation would emerge: only China, and particularly Beijing, would display a multitude of circular and rectangular enclosures, often nested within one another—large circles containing medium ones, which in turn contain smaller ones, and even tiny ones within those. The pinnacle of these 'enclosure walls' includes global wonders like the Great Wall and the majestic, secluded Forbidden City. Zooming in on Beijing, one can clearly see how various old and new compounds, along with their surrounding walls, dissect the urban landscape. This configuration leads to a sparse road network, where internal road resources, though extensive within compounds, are cut off from external access by gates. Historically, ancient Beijing featured four layers of fortifications—the outer city, inner city, imperial city, and palace city—all walled with limited external access points, famously described as 'nine inner gates, seven outer gates, and four imperial city gates.' Today, during peak commuting hours, the throngs of vehicles pushed onto the ring roads virtually form new 'city walls' of congestion, with many 'notorious' segments resembling slow-moving parking lots. Furthermore, insufficient radial thoroughfares and complex intersections mean that what were once efficient overpasses and ring road exits now act as Beijing's new 'checkpoints' and 'city gates' due to severe traffic jams.
