City of Santa Ana I First Street Multimodal Corridor <br /> Technical Memorandum <br /> VISSIM looks at each vehicle as is travels along the network. This allows for more accurate <br /> operational analysis and travel time modeling by travel model (passenger vehicle versus bus <br /> for example). <br /> In order to accurately assess traffic conditions using VISSIM, multiple model runs are <br /> conducted, and the results are averaged. The model is then compared to existing conditions <br /> and calibrated until the delay and travel time accurately reflects the analyzed and observed <br /> conditions. Table 5 reports the intersection delay using VISSIM for each of the study <br /> intersections. <br /> Table 5.
