What traffic sign is the Langwang P symbol?
1 Answers
The Langwang symbol is a parking area sign. It appears in the driver's license test signs, featuring a P with an arrow symbol, Langwang, and a cup symbol, indicating a parking area. This sign is used to indicate the location of a parking area and is placed at the starting point of the deceleration lane. In China, modern road traffic signs are divided into two main categories: primary signs and auxiliary signs. Primary signs: Primary signs can be further classified into four types based on their meanings: warning signs, prohibition signs, mandatory signs, and guide signs. Auxiliary signs: There are five types of auxiliary signs, which are attached below primary signs to provide additional information. These signs cannot be used independently. Auxiliary signs are further categorized based on their purpose, including time-related, vehicle type-related, distance-related, warning and prohibition reason-related, and combined auxiliary signs. They are rectangular in shape with a white background, black text, and a black border. Additionally, there are variable traffic information signs that display real-time information based on road conditions (such as construction, congestion, traffic flow, direction changes, weather conditions, etc.), conveying messages to drivers and pedestrians. The functions of traffic signs include the following three aspects: Visual information: 90% of the information received while driving is visual. Human visual characteristics, such as depth and width of vision, eye movement, color recognition, effects of brightness and glare, speed judgment, etc., are fundamental considerations in setting up traffic signs. Information needs: Almost all information is received through visual communication. Therefore, when setting up traffic signs, attention should be paid to their visibility, comprehensibility, reliability, and positioning. Information processing: A driver's task includes acquiring information, processing it, selecting an action plan, implementing it, and repeating the process to observe the results. Due to the limitations of human behavior and the complex relationship between drivers, vehicles, and road environments, this process is highly intricate. When setting up traffic signs, factors such as driver expectations, reaction time, and short-term memory should also be considered.
