Entering a large shopping mall, the various floor signs on the B, L, LG floors often leave people confused. Finding a store in the mall is already troublesome enough, that's good, I don't even know which floor it is on. ”Mr. Qu, a reader from Shanghai, made an appointment with a friend to have dinner at a restaurant in a shopping mall. He thought that LG2 was the first floor above LG1 and searched around repeatedly. Upon inquiry, I found out that LG is actually an abbreviation for the lower ground floor, while LG2 refers to the underground second floor located below LG1. Mr. Qu couldn't help but exclaim, "Is it necessary for the signage in public places to be so complex?" Like Mr. Qu, some readers have reported that the floor signage in public places such as shopping malls, supermarkets, and office buildings is complex and lacks uniformity. L floor is the most common abbreviation for a floor, referring to the number of floors above ground level. However, in some hotels, L is used as the English abbreviation for the lobby, so L1 floor is not the ground floor, but the floor where the hotel lobby is located. For example, the M floor is usually the abbreviation of the mezzanine in English, often used for parking lots, but in some places, M has become the abbreviation of the subway line, pointing to the road leading from the parking lot to the subway. Some parking lots not only have complex floor signs, but also have problems with vehicle guidance signs. The signs of the underground parking lot in Guanggu Joy City are simply misleading, and the signs are particularly small and hidden. "Ms. Ding, a reader from Wuhan, Hubei, went shopping on weekends and walked up and down the B1, B2, and B3 floors several times when leaving the parking lot." The arrow signs of the underground parking lot are contradictory, clearly indicating the exit, but following the exit signs, she returned to the B2 floor. ”As a result, the parking lot was congested due to unclear signage. After Ms. Ding shared her experience on social media, it resonated with many users. Due to the limited time free parking policy at Optics Valley Joy City, there are already many people coming here to park, and the unclear signage further exacerbates the congestion. Regarding this situation, Guanggu Joy City replied to Ms. Ding, 'We will work with relevant departments to strengthen guidance and optimize the entry and exit routes of vehicles within the venue.'. In addition to floors and parking lots, unclear subway signage has also attracted readers' attention. Ms. Mo, a reader from Chengdu, Sichuan, recently traveled to Xi'an, Shaanxi for tourism. However, due to the subway signage at Xi'an North Station, she was delayed and almost missed the high-speed train on her return journey. Xi'an North Station is a transfer station for Metro Line 2, Line 4, and Line 14. The up and down directions of the line are not in the same waiting hall, and passengers need to carefully distinguish between them. The transfer guidance of the subway makes people feel confused. "Ms. Mo, as an outsider, ran many times throughout the station before finding the correct way. Not only do tourists from other places get confused when transferring, but some local citizens also walk the wrong way on the transfer channel of Xi'an North Station. Ms. Chai and her family transferred here a few months ago to catch a flight. They followed the signs and crossed the slope and a long passage from Line 2 to Line 14. When they arrived at the platform of Line 14 by elevator, they realized that it was not the direction to the airport, so they had no choice but to get off the elevator and navigate again. The transfer was already far away, dragging a large box and taking the wrong route was too exhausting. It is suggested that the subway operator post more transfer signs on the ground to go to the airport, "Ms. Chai said. In the fast-paced urban life, the signage system in public places plays the role of a silent guide, carrying multiple functions such as guidance, notification, and warning. It should provide accurate, clear, and easy to understand guidance information to ensure that every user can quickly and accurately find their destination. ”Liu Peng, a professor at the School of Public Administration of Renmin University of China, said that some planning designers one-sided highlighted distinctive creativity, even blindly pursued fashion and foreign style, ignoring the actual function of logo guidance, which led to the logo's beautiful appearance but not clear, which is the inversion of the order. "Instead of playing its due role, it has set up a 'psychedelic array' to confuse users who are not familiar with the surrounding environment." Many cities have clearly regulated the role of logos in public places. The "Standardization Management Measures for Public Information Signs in Guangzhou" define the role of public information signs as "indicating the purpose and location of public places and facilities, and prompting and guiding public behavior". Liu Peng believes that the introduction of regulations does not guarantee that all public place signs can achieve their intended purpose, and there are deficiencies in the design of public place signs in some places. Firstly, the design standards and specifications are not unified, and the signage styles vary greatly in different cities, regions, and scenarios, resulting in barriers to information transmission; Secondly, the design of signage did not take into account the actual needs of users and could not optimize public signage from a practical perspective. Although the signage is small, it reflects the level of refinement in urban governance. ”Liu Peng suggests that the design of signage in public places should consider issues from the perspective of users, highlighting practicality and service. "The clearer the signage, the better, and the simpler the text, the better. While ensuring that citizens can understand, cultural or creative colors should be appropriately added, and the essence should not be sacrificed
