How 4D Visualization and Simulation Enhances Work Zone Safety and Traffic Mobility

There are multiple impacts on road users and construction workers due to highway construction activities that vary with time and location. A Four Dimensional (4D) visualization of construction work zones has the potential to identify the most significant impacts on the users and construction workers. In addition, it also aides the project planners with a better understanding of work zone impacts and effectiveness. This research demonstrates an application of work zone visualization to support intermittent, dynamic work zone deployment on a state highway project in the United States. Initial reviews of the 4D visualization demonstrate essential analytics and spatial transformations of the project with respect to time and location which would help in analyzing the diverse situations and possible impacts of work zone configurations with relative simplicity.
