Estimating the number of hours wasted in traffic each year is a complex task that requires taking into account a variety of factors, including population density, traffic volume, road infrastructure, and more. However, some studies have attempted to estimate the total number of hours that people in a given city or region spend in traffic each year. According to a 2019 report by INRIX, a transportation analytics company, drivers in the United States spent an average of 99 hours in traffic congestion during peak hours in 2019. This represents a slight decrease from the previous year, but still amounts to a significant amount of time wasted. The report also found that the most congested city in the United States in 2019 was Boston, where drivers spent an average of 149 hours in traffic congestion during peak hours. Other highly congested cities included Chicago, Philadelphia, New York City, and Washington, D.C. Overall, the amount of time wasted in traffic each year represents a significant economic and social cost, as it leads to lost productivity, increased fuel consumption, and negative impacts on quality of life. As a product manager, it's important to keep these factors in mind when designing transportation-related products or services, and to work towards solutions that can help alleviate traffic congestion and improve overall transportation efficiency.
