Abstract: An analytical-based dynamic traffic assignment (DTA) model intended for off-line analysis and evaluation of non-recurring lane-blocking events is proposed. Formulated as a variational inequality (VI), this model solves an ideal dynamic user-optimal (DUO) route choice problem. A diagonalization algorithm is proposed to solve the model to a prespecified convergence using a large-scale, real-life traffic network. Adjustments of link capacities triggered by external lane-blocking events and internal modeled traffic phenomena are explicitly considered in the solution algorithm to capture queue formation and dissipation. The proposed solution procedure approximates route choices based on anticipatory and non-anticipatory traffic conditions to account for potential enroitte diversions caused by non-recurrent lane-blocking events. Model implementations, computational results, and conclusions are presented and discussed. The proposed model, solution procedure, and associated features demonstrate capabilities for realistic network-wide applications with ATMIS implications. Copyright © 2001 Taylor & Francis.
