The problem of designing coordinated control strategy for on-ramp and adjacent intersection in urban expressway network is considered in this paper. Short-term traffic volume forecasting and incident detection are adopted for the estimation of traffic conditions, which are categorized into different states according to traffic flow saturation level. Adjacent intersection traffic signal control, on-ramp...
Spacing Policy is an integral part of Adaptive cruise control (ACC) system and determines the performance of ACC system in safety, driving comfort and fuel consumption. The traditional variable spacing policy fails to consider the acceleration of the previous vehicle, and it performs poor when velocity of the previous vehicle changes frequently. To solve this problem, this paper takes into account...
In collisions with trucks, there is a high risk for car occupants to sustain severe or fatal injuries. The intelligent rear under-run protection system, as a very important part to prevent under-run accidents and decrease loss, its dynamic deformation and stress distribution mostly lie on the characteristic of energy absorber and keeping directional stability of the rear vehicle during collision....
Based on the analysis of the steering performance, the objective of this paper is to present evidence for the tractor adopted the four-wheel steering (4WS) which can improve the handling and stability of tractor semi-trailer. The simplified single track model with 3 DOF for 4WS tractor semi-trailer has been constructed for dynamic simulation through time-domain response on the two states of small...
A new bicycle model based on cellular automata was presented in this paper, which was built according to analyzing the characteristics of bicycle flow and the riderspsila behaviors. The bicycle had two moving direction in this model and the s-track could be simulated through this model. Several simulations were operated under periodic boundary condition to validate the accuracy of the model. The simulation...
