Abstract
An integrated control method of on-ramp and correlated intersection is proposed in this article. The object is to minimize the average vehicle delay on-ramp and intersections based on the precondition that expressway is unblocked. ALINEA control approach is adopted for ramp study while cell transmission model was chosen and ameliorated for urban traffic. The demand of on-ramp is gotten by traffic state and all the control parameters of correlated intersection according to ameliorated model. With the integrated control method proposed in this article, the cycle and green time of intersection can be optimized dynamically to maximum the whole bendfit of expressway and surface street. The control approach have been illustrated via a simple case study, which shows that the integrated control approach proposed in this paper resulted in a reduction of 7.9% in the average vehicle delay compared to fixed-time control.
