In order to accurately evaluate the impact of the implementation of Intelligent Transportation Systems (ITS) services such as route guidance and Advanced Traveler Information Systems (ATIS), a Simultaneous Route and Departure time choice (SRD) model is needed. This paper develops a cell-based SRD formulation for the case of elastic total demand through the Variational Inequality (VI) approach. This formulation follows the ideal Dynamic User Optimal (DUO) route/departure time choice principle and the First-In-First-Out (FIFO) conditions. It encapsulates a network version of the Cell Transmission Model (CTM) to improve the accuracy of dynamic traffic modeling. To solve the formulation, we adopt a descent method developed for co-coercive variational inequality problems. In the numerical study, we solve a 13-node, 19-link network to demonstrate that the solution of this formulation satisfies the ideal DUO route/departure time choice principle precisely.
