To analyze several traffic indices dynamically and explore the relationship among the indices, a model for multi-lane freeway traffic based on Cellular Automata (CA) theory is proposed in this paper. In the proposed model, vehicle movement is categorized into cellular behavior as chasing, overtaking, changing lane, accelerating and decelerating, cellular status is categorized into velocity change...
Considering the low performance of accuracy and convergence of the traditional Singer algorithms for maneuvering detection, this paper proposed an improved Singer algorithm which deals with the adjustments of the matrix of the process noise covariance and changes of the filtering gain according to the average attenuation of innovation and the filtering value of acceleration. The new algorithm can...
