Postoptimality analysis methodology for applying linear programming (LP) to freeway on-ramp control is presented. In addition to the optimum control strategy for the original data set, the analyst is provided with much valuable information concerning the deviations from the initial capacity and upper bound estimates. Not only are ranges of optimality given with their associated changes in the value of the objective function, but the corresponding control strategies are also provided. The expense of generating this information is negligible, simple calculations are required, and the computerization of these calculations can be considered as a one-time effort. The methodology developed in this study is also applicable to priority-entry LP on-ramp control.
