Virtual reality visualization of microscopic traffic simulations

Traditional microscopic traffic simulations visualize simulation results in two dimensions. Visualization in three dimensions provides additional versatility to these simulations and allows the utilization of their results for additional purposes. An approach to visualization of CORSIM simulations in three dimensions with the use of a personal computer-based virtual reality package is presented. The key to this approach is translation of the network geometry and traffic data, which is done by a specially designed middleware program. A practical simulation problem is presented to demonstrate the visualization procedure and its assessment. Potential improvements over the current work are discussed.
