  • Patent number: 10809723
    Abstract: Embodiments of the present disclosure disclose a method and apparatus for generating information. A specific embodiment of the method comprises: acquiring associated information of a road to be evaluated for driving difficulty; generating traffic environment information of the road based on the associated information; and inputting the traffic environment information of the road into a driving difficulty evaluation model to obtain a driving difficulty level of the road for an autonomous driving vehicle. The driving difficulty of the road for the autonomous driving vehicle is evaluated, to obtain the driving difficulty level of the road for the autonomous driving vehicle. Thus, based on a driving difficulty level of each road for the autonomous driving vehicle, the autonomous driving vehicle may select a road having a low driving difficulty level to drive.
