There are extremely strict requirements on the length and width of the dedicated venue, road conditions, safety measures, etc. Generally speaking, the dedicated stadium is a ring, with each lap being 3 to 7 kilometers long. The total length of the track should not be too long, which is 305 to 320 kilometers. For safety reasons, wide grass or sand areas are generally laid on both sides of the track to separate spectators from the track. Among the many venues for official competitions today, the track in Morocco is the shortest (3.328 kilometers), and the Spa-Francorchamps in Belgium is the longest (6.94 kilometers). The FIA ??stipulates that the track does not allow too many long straights. The purpose is to limit high speeds to avoid danger. Generally, for a standard F-1 racing venue, the following equipment is essential:

Track - 7~11 meters wide and 3.0~7.0 kilometers long. To avoid excessive vehicle speeds, numerous curves must be provided.

The starting and finishing straights are 12 meters wide and 250 meters long. Two cars can be placed side by side without being too crowded.

Grandstands--need to be separated from the track by barbed wire and 1.2-meter-high railings.

Cameras and TV towers--used for television broadcasts.

Large-screen TV--placed opposite the stands to facilitate spectators in the stands to understand all the game conditions.

Safety personnel observation station - located in a relatively dangerous area, for safety personnel to keep the track clear, deal with various accidents, and issue warning signals to drivers of potential dangers, etc.

Helicopter - ready to provide emergency rescue to injured riders.

Medical station - a protected location next to the repair station, equipped with operating room and first aid room.

Repair station--each team is equipped with one, which is a permanent facility.

Sponsor reception stand - located on a high platform behind the pits, overlooking the pits.

Paddock--a parking area for transport vehicles and campers.

Race control tower--located on the second floor of the entire control tower, overlooking the entrance to the repair station, where commanders communicate with safety personnel through radio devices to control the progress of the race.
