Specifically, the design and improvement of the subway last week, including road map and arrival information tips, are convenient for people to travel, charging facilities and traffic tips at the exit can bring more convenience to people. The road map and arrival information tips set on the first subway facilitate people's travel. On the subway, the route map and arrival information tips of this subway line are set up. These information tips bring great convenience to people who take the subway, especially foreigners. Because they are not familiar with the subway station, these information tips bring them greater convenience, so this design is very intimate. Secondly, the charging facilities on the subway provide great convenience for people. In our daily life, mobile phones and other devices have become indispensable tools and are often used when traveling. However, the battery of this kind of equipment will be dead after a period of use, which brings us inconvenience. Now there are many charging facilities on the subway, which brings a lot of convenience to people. This design is also very intimate. Third, after the subway leaves the station, traffic tips should be added to provide more convenience for people. In order to make it more convenient for people to travel by subway, I personally think that the information of the transportation system after leaving the station should be increased to help people understand the traffic situation around the subway exit and provide more convenience for people to travel. This intimate design will make it more convenient for people to travel by subway in the future. Especially for foreigners, taking the subway can effectively avoid getting lost. Therefore, it is necessary and sure to achieve good results by adding this design.
