The use of 3D modeling in simulation has become the standard for both the military and private sector. Compared to physical models, 3D models are more affordable, more flexible, and can incorporate complex operations. Unlike a physical model, a dynamic virtual model can react to environmental variables or user input. Additionally, virtual models can be run in the context of other dynamic behaviors such as working traffic lights, functioning train crossing gates, moving vehicles, and air quality analysis. A simulation allows you to interact with the space and explore areas that you want to see more closely. And if you want to see more detail in something that hasn't been modeled, it takes less than half an hour to go back to the model, make changes, and bring it back into the simulation. Traffic simulation models such as VISSIM, WATSIM, and PARAMICS are on the forefront of integrating 3D visualization packages into their systems. The easy to use multimedia user interface and fast interactive response provide a powerful tool for urban traffic and environmental planners. At this time this technology is still cutting edge and an evaluation of current use and innovations is paramount to wider transportation industry acceptance. (Author/publisher)
