Ground crossings vary in their public health relevance. While some are used mainly for trains or cargo transport and rather link to environmental hazards, others can have a traveler volume of 30,000 to 50,000 per day, often involving queues and waiting times. Some ground crossings are located close to populated areas and big cities, while others are in remote or mountainous areas. States Parties may designate ground crossings to have capacities aimed at protecting the health of travelers and populations, and at containing public health risks at source.
Designation of ground crossings should be based on public health risk assessment following the general designation criteria for points of entry.
