Abstract |
The effective presentation of traffic impacts to a broad range of public and private constituencies is an essential part of the approval process for proposed improvements to transportation infrastructure. The increased sophistication of audiences and demand for greater participation by the public in decision-making processes makes effective public education an essential component of transportation planning efforts. A tool was developed for the interactive visualization of traffic impacts (IVTI) that offers clear, comprehensive, and effective views of proposed transportation enhancements. IVTI is essentially a tool for visualizing and organizing the output of traffic engineering models. Its main advantages compared with those of existing traffic simulation and animation programs are that IVTI does not require any training for users to understand the displayed results; roadway layouts and vehicles are photorealistic instead of simplified geometric representations; and adjacent land uses are in full display, which permits a more direct assessment of the consequences of the proposed traffic plans. The traffic model currently employed by IVTI is TRANSYT-7F. The IVTI system has two primary components: a development system and a delivery system. The development system generates a template of the presentation into which the audio, video, and image assets are captured in digital form and integrated into the general presentation framework. The TRANSYT-7F analysis results are imported into IVTI and converted into data structures (e.g., roadways and vehicles), resulting in a photorealistic visualization of the underlying model. The delivery system, a scaled-down, portable version of IVTI equipped with video projection capabilities, enables interactive presentations of the visualizations of the subject transportation improvement to an audience.
