The invention provides a traffic guidance method and system for sensing twinborn based on an intersection. The method comprises the following steps: S1, carrying out driving simulation on a pre-constructed road section live-action three-dimensional model, and obtaining the number of vehicles arriving at the transverse simulation and the number of vehicles arriving at the longitudinal simulation in the longitudinal passing time; s2, determining the number of transverse waiting vehicles and the number of longitudinal waiting vehicles after the transverse passing duration is ended based on the vehicle information acquired by the roadside sensing unit; s3, determining a transverse target traffic number according to the transverse simulation arrival vehicle number and the transverse waiting vehicle number, and determining a longitudinal target traffic number according to the longitudinal simulation arrival vehicle number and the longitudinal waiting vehicle number; and S4, determining the transverse traffic duration of the next control period according to the transverse target traffic quantity and the longitudinal target traffic quantity. Through combination of virtual and real information, transverse passing time can be rapidly obtained, traffic light time control according with reality is realized, and traffic jam is reduced.
