Ask whether there are more people on weekends compared to weekdays, leading to traffic congestion and the like? Can private cars enter, and is there a fee required? Thank you for your reply.

Weekends are busier than weekdays, and driving is prone to traffic jams. After all, that road is not only a scenic area road but also a provincial road. Private cars are allowed in, but there is a toll charge.
