Liangjiang New Area National Connected-Vehicle Pilot Zone
In January 2021 Chongqing's Liangjiang New Area became China's fourth — and the first in western China — national-level connected-vehicle (C-V2X) pilot zone, tasked with wiring roads and intersections with roadside cameras, LiDAR and radar so vehicles can 'see' beyond their own sensors. By mid-2022 the zone had an 11km demonstration corridor live in the Longsheng area and a separate 55km network of test roads split into trial, pilot and roll-out tiers, plus a section of the G5021 Shiyu Expressway running more than 30 C-V2X connected-vehicle use cases. The programme is organisationally distinct from Baidu's Apollo Go robotaxi permit in Yongchuan, another Chongqing district — no citywide, independently measured traffic or safety outcome was found for either.
📊 Impact
11km Longsheng-area demonstration corridor and a separate 55km trial/pilot/rollout test-road network live by mid-2022; a section of the G5021 Shiyu Expressway runs 30+ C-V2X use cases (operator/trade-press reported). No independent measurement of traffic-flow or safety outcomes was found.
🎓 Lesson
A 'national pilot zone' label describes a regulatory designation, not a finished, city-scale system — three years in, the verifiable footprint is still a handful of kilometres of road.
