Samenvatting
Yrevious solutions of the highway - r,rnsaing problem haveaeaumed independence between headwaus on the major road. Philpaper introduces a amall correlation between sacceasiveexponential headwa5s, where the de0enerate case of zero coree-lation corresponde to the familiar Paisson traffic strearo.The coreelated model is inveatit,ated and comparisons are madewitti the equivalent Poisson case.
