A Pavement Network Optimization System Using Dantzig-Wolfe Decomposition, described. A set of linear programs are generated from underlying Markovian Decision Process optimization models, and these are then coupled together through the artful use of Dantzig-Wolfe decomposition. The NOS can be used, in long-term or short-term planning modes, to minimize cost subject to pr

Congestion Toll Pricing of Traffic Networks,tor . is defined to be a ., if the set of tolled user equilibrium solutions is a subset of the set of untolled system optimal solutions. The problem of characterizing the toll set ., which is the set of all valid toll vectors, is studied. Descriptions and characterizations of τ are given for the cas

Solving the Nonadditive Traffic Equilibrium Problem, simply the sum of the costs on the arcs that constitute that path. The method we describe is based on the recent NE/SQP algorithm, a fast and robust technique for solving nonlinear complementarity problems. Finally, we present an example that illustrates both the importance of using nonadditive cos

A Communication Assignment Problem on Trees: Heuristics and Asymptotic Behavior,odes. The centers exchange messages at given rates per time unit. If there is no direct connection between centers .. and .., the messages sent from .. to .. are routed through several intermediate centers. The goal is to find an embedding of the centers into the nodes of . which minimizes the maxim

,Distributed Disaggregate Simplicial Decomposition — A Parallel Algorithm for Traffic Assignment, decomposition, regularization and partial linearization. The parallel implementation is a synchronous, single program multiple data, algorithm using local load balancing. PVM is used for communication purposes. We present numerical results for two parallel platforms: a DEC Alpha cluster and a Parsy

Two Special Cases for Rectilinear Steiner Minimum Trees,g the rectilinear Steiner minimum tree is NP-hard [2]. In this paper, we present two polynomial-time computable special cases. As an application, we also give a simple way to compute the rectilinear Steiner minimum tree for four, five, and six points.
