Final answer:
Pedestrian traffic in the U.S. is characterized by several traits but does not include a person standing up from a seated position. Safety concerns arise at busy intersections, and traffic signals can help manage flow. Urban planning faces challenges due to a transportation system designed primarily for cars.
Step-by-step explanation:
Pedestrian traffic in the U.S. is characterized by a number of features, but it does not typically include a person standing up from a seated position. This activity is not representative of pedestrian traffic patterns or safety concerns.
Pedestrian safety is a significant problem, particularly around busy intersections near campuses where students and others must navigate vehicular traffic. A traffic signal is one measure that could improve safety by regulating the flow of pedestrian and vehicular traffic.
In comparison to some parts of Europe, where public transportation, walking, and bicycling are emphasized, the U.S. transportation system is heavily geared towards accommodating cars through interstate highways. This leads to challenges in urban planning for free-flowing transport and pedestrian mobility.
The rise of service industries and increased access to passive transportation, like automobiles, has led to a decline in walking and an increase in driving in the U.S.
