According to the Central Epidemic Command Center, since the scales and types of the national scenic areas, national parks, and national forest recreation areas in Taiwan are different, both common and individual rules for traffic control apply. The common rules focus on traffic flow. If a parking lot is 50% full, text messages will be sent to people in the vicinity, so that they can adjust travel plans if necessary. The public will also receive instructions on how to utilize the area’s road systems and find other parking spaces.
