Aiming at the two question:dual-beam laser Doppler velocimeter can not measure the velocity out of focus and the running road surface of the ground navigation system fluctuates usually,the paper put forward and designed the reference-beam laser doppler velocimeter to measure the transverse velocity of moving surface.

In typical city traffic situations the additionally to the radar measurement even the lateral velocity component of each detected target such as a vehicle is of large interest.

Study on prediction of lateral acceleration of tilting train based on linear adaptive neural networks;

This paper has carried on the impact of comfort results from acceleration and deceleration,and then obtained the computing formula of lateral acceleration in various situations and the impact of comfort results from different lateral acceleration rate.
