To bolster the "AI + Transportation" initiative, the Ministry of Transport has spearheaded the formation of the Transportation Large Model Innovation and Industry Alliance, outlining the holistic technical framework of the "1+N+X" integrated transportation model. This architecture comprises a universal technical foundation, N diverse vertical domain models, and X scenario-specific agents. The implementation of this architecture is currently being expedited, with 860 typical application scenarios identified, prioritizing those with high-frequency and rigid demands. The initial batch of agents will be integrated into the National Integrated Transportation Information Platform, and efforts are underway to catalyze R&D and application through an innovative application competition. Furthermore, the development of a "four platforms and one hub" industrial ecosystem is progressing, aimed at invigorating market dynamics and fostering societal innovation.
