Following is a definition that has been used to describe the technology known as visualization: Using the computer to convert data into picture form. The most basic visualization is that of turning transaction data and summary information into charts and graphs. Visualization is used in computer-aided design (CAD) to render screen images into 3-D (three-dimensional) models that can be viewed from all angles and which can also be animated. This definition, although useful, is just one of many definitions that have been used for the term. Varying definitions have led transportation planners, designers, and engineers to interpret visualization differently. To combat this confusion, transportation agencies look to other agencies for help in addressing their needs for visualization. This synthesis focuses on the best practices and experiences with leading transportation agencies that are developing and incorporating visualization into the 'preconstruction' component of the project development process. |
