Study time periods are selected such that they include the time prior to the buildup of congestion and end after the dissipation of congestion. A simulation model is developed for a period of time that is necessary to replicate the full extent of congested traffic operations within the study area peak period or peak hour. For models that are oversaturated, the study period is typically expanded to include the buildup and dissipation of congestion. Otherwise, a peak hour analysis and seeding period (the initial time it takes for the model to represent real-world conditions) may be sufficient. The seeding period is typically at least twice the minimum amount of time that it takes one vehicle to traverse the longest extent of the network. The peak hour is defined as four consecutive 15-minute intervals of turning movement traffic count data that represents the highest traffic volume in an hour. A peak period consists of two or more hours, including the time segment when traffic demands are highest and traffic operations are typically sub-standard. Land use adjacent to the project is considered as it may impact not only the time when data is collected, but also which study time period to use.
