This paper discusses partitioned strategies for lane assignment in automated highway systems (AHS) having three lanes for (semi)-automated driving. The authors discuss the functional role of lane assignment. Next, the authors classify lane assignment strategies into nonpartitioned (chaotic, unconstrained and constant lane) and partitioned (destination monotone, origin monotone and monotone) strategies. An optimization problem is formulated with performance criterion being a combination of travel time and maneuver costs. Conditions under which the optimal strategy is partitioned, or nearly so, are discussed. Finally, a case study of a 20 section highway and the strategies obtained for it under the minimization of total travel time criterion is presented.< >
