Peak hour factor is a term used in transportation planning and engineering to describe the level of traffic during the busiest period of the day. There are several synonyms that can be used to describe this concept, including peak traffic volume, rush hour congestion, peak demand period, maximum traffic intensity, and critical time period. These terms are often used interchangeably depending on the context and the specific focus of the research or analysis being conducted. Regardless of the terminology used, the goal is to understand the challenges and opportunities associated with managing high levels of vehicular traffic during periods of peak demand, and to develop effective strategies for improving the flow of traffic and minimizing congestion.
