Analysis of Vehicular Behavior at Bottlenecks Considering Lateral Separation

The vehicular behaviors at bottlenecks are complex, and lateral separation makes traffic flow more unstable. Based on the lateral separation characteristic, this paper analyzes the vehicular behaviors at traffic bottlenecks and the movement is described. What’s more, video recognition technology is introduced to obtain the track of the vehicle to verify the decision-making process. The lane-changing behavior and gap-following behavior can be predicted well. And in further study, more factors should also be considered.
