Abstract
This study proposes the dynamic inflow control model incorporating Linear Programming approach. This model can explicitly consider the time-dependent changes in both the inflow demand and the traffic condition on the network to estimate the optimal inflow at on-ramp which can make the capacity of urban expressway more efficient use. Especially, the speed-density relation of each link is introduced into the inflow control model to predict precisely time-of-day dynamics of traffic condition on the network. In addition, the constraint of link travel speed, as well as the constraint of link capacity, is included in the inflow control model both to prevent traffic jam and to encourage recovery from slight jam. This study examines the significance and usefulness of the proposed model through the simple numerical experiments.
