Periods of peak traffic congestion, occurring typically in the mornings and evenings, significantly impact commuters and transportation systems. For example, major metropolitan areas often experience increased vehicle volume between 6:00 AM and 9:00 AM, and again from 4:00 PM to 7:00 PM on weekdays. These timeframes represent elevated demand on roadways.
Understanding these congested periods is crucial for efficient urban planning, transportation management, and individual travel decisions. Historically, population growth and increased vehicle ownership have contributed to the intensification of these peak traffic times. Mitigating their negative effects through infrastructure improvements and alternative transportation options offers substantial benefits to economies and individuals.
