The invention relates to an intersection waiting queue estimation method based on a vehicle kinematics model, which is an estimation method for calculating the static length, the dynamic length, the passing time and the passing speed of a waiting vehicle queue by adopting the vehicle kinematics model and considering the characteristics of a heterogeneous vehicle queue when an intersection signal lamp is a red lamp under the urban road condition. The related waiting queue estimation method mainly comprises a waiting queue vehicle quantity statistics method based on a geomagnetic coil, a vehicleparameter random calculation method based on Gaussian distribution and a queue motion track calculation method based on a kinematics model. According to the estimation method, existing mature technical conditions are utilized; under the condition that the intelligent network connection automobile technology is not popularized on a large scale, accurate estimation of the movement track of the waiting queue at the urban road intersection can be achieved, and an accurate and reliable calculation basis is provided for the technologies of vehicle economical driving, green passing, intersection efficient passing and the like.
