Do you think new technology will make your city better to live in?
Chinese companies presented urban mobility and service technologies at the Smart City Expo World Congress, held Nov. 3 to 5 in Barcelona. The congress carried the theme 'Urban Solutions, Real Impact.'
Why it matters
The showcase highlights how cities are exploring new tools for transportation, energy, and public services as urban planners seek practical solutions. The presence of major technology firms signals growing international interest in smart city infrastructure.
EHang displayed an electric aircraft designed to carry two people that takes off and lands vertically, requiring little infrastructure. The source does not specify certification status or commercial availability timelines for the aircraft.
The players
Nvidia
A U.S. semiconductor company whose graphics processors are widely used to train and run artificial intelligence models.
Microsoft
A U.S. technology company that provides cloud computing and artificial intelligence services to governments and enterprises.
Dell
A U.S. computer hardware manufacturer that sells servers and infrastructure used in data centers and smart city systems.
The details
Exhibitors demonstrated humanoid robots for reception, traffic management, and hospital services, an automated kitchen that prepared French fries, and stand-alone solar streetlights that need no underground cabling. Kapsch presented a pilot using artificial intelligence to manage traffic signals in Barcelona, and University College London showed simulations of pedestrian crossings from the perspective of people with dementia-related visual impairments.

The Tech Race
The Barcelona-commissioned pilot, in which Kapsch applied artificial intelligence to manage traffic signals, is presented alongside Nvidia and Microsoft's presence at the congress. Together these exhibits show Chinese and Western firms competing to supply cities with AI-driven urban infrastructure.
Residents of cities adopting these tools may see changes in traffic signal timing, streetlight installation, and public service automation. Pricing and deployment timelines for the displayed technologies were not reported in the source.
The takeaway
Smart city projects increasingly depend on AI, networking, and automation working together, so readers following urban technology should watch for pilot results rather than exhibition demonstrations alone.
