Abstract:With the rapid development of science and technology, the low-altitude logistics, as an emerging field, has brought new opportunities for the optimization of urban ground transportation network. Focusing on the “Strong Transportation Nation” strategy and "New Infrastructure" background, aiming at the traffic bottleneck problem under the special terrain of "two mountains and one river" in Lanzhou, a low-altitude - ground traffic countermeasure model is proposed to study the collaborative countermeasures for low-altitude logistics and ground transportation in the era of intelligent transportation in Lanzhou, which provides the theoretical support and practical guidance for solving the urban spatial constraints of the Yellow River Valley and building a modern transportation system, and fills in the relevant research gaps in the northwest region.
