Robotaxi trips in Wuhan overlap with demand for human-driven taxis, but a study of the city's ride records also finds room to operate a smaller, less energy-intensive autonomous fleet. The researchers analyzed more than 4 million taxi and robotaxi orders and modeled how different dispatch and ride-sharing choices could change the fleet's daily operation. Their analysis was published September 22 in Nature Sustainability.
The robotaxi orders came mainly from street networks the authors classify as less complex, so the records do not represent uniform service across Wuhan. Around metro and bus stops, robotaxis made a smaller share of trips between stations than human-driven taxis did. The authors interpret that pattern as compatible with a service that complements public transport, even as robotaxis compete with taxis for on-demand rides.
In an upper-bound scenario that optimized dispatch and shared rides, the model cut the required robotaxi fleet size by 62.5% and daily energy consumption by 44.8%. These are estimates for a different way to run the fleet, not savings measured in Wuhan's operating service. The study draws on one city's orders; an operating trial would have to test whether the modeled reductions can be achieved.
