In today's fast-paced travel life, transportation hubs play a crucial role as they gather a large number of people from all directions, becoming one of the most densely populated areas in the city. As a convenient retail terminal, vending machines have also been deployed in transportation hubs such as train stations, bus stations, subway stations, and airports. In this process, there are intricate connections between foot traffic and sales revenue, which profoundly affect the operational efficiency and development prospects of vending machines.
1、 Characteristics of pedestrian flow in transportation hubs and their impact on vending machines
（1） Large and consistently stable foot traffic
The transportation hub receives and transports numerous passengers every day, whether it is weekdays or holidays, and there is basically no prolonged interruption in personnel flow, with a consistently high level of foot traffic. For example, during the Spring Festival travel rush, the daily passenger flow of large train stations can reach hundreds of thousands of people; The busy subway station is also crowded during peak hours in the morning and evening. This large and consistently stable flow of people provides ample potential customers for vending machines, meaning there are more opportunities to convert passersby into actual consumers, thereby laying a solid foundation for increasing sales.
（2） Diverse population composition
The flow of people in transportation hubs comes from different regions, age groups, and occupational backgrounds, with diverse consumption needs and preferences. Business people in a hurry may be more inclined to purchase convenient and fast foods such as coffee and sandwiches to replenish their energy; Families who travel abroad may be interested in snacks, drinks, and souvenirs with local characteristics; There are also a large number of ordinary commuters who may choose small items such as drinking water and chewing gum for their daily needs. Vending machine operators need to fully consider the diversity of this population, accurately configure products to meet the needs of different types of passengers, thereby increasing the probability of products being purchased and promoting sales growth.
（3） The duration of stay varies
There are significant differences in the duration of stay for passengers at transportation hubs. At subway stations, most passengers only make brief stops and may only have a few minutes to get on and off the train; At train stations and airports, passengers may arrive longer in advance and need to wait and wait for trains, often staying for tens of minutes or even hours. For passengers who stay for a short period of time, they pay more attention to the convenience of purchasing, and products that can be quickly obtained are more favored; For passengers who stay for a long time, they may have more time to browse and compare the products in the vending machine, and even be willing to try some new and unique products. Operators need to reasonably arrange the location of vending machines based on the characteristics of passengers' stay time in different regions, and adjust the types and display methods of goods to adapt to different consumption rhythms and maximize sales.
2、 The positive correlation between foot traffic and sales revenue
（1） Basic quantity correlation
Generally speaking, under the same conditions, the larger the pedestrian flow at the transportation hub, the more exposure opportunities the vending machines will receive, and the frequency of use will also increase accordingly, directly driving up sales. For example, if two vending machines with the same configuration and product types are placed in a remote corner of a bus station with low passenger flow and a waiting hall of a train station with high passenger flow, after a period of operation comparison, it will be found that the sales revenue of the vending machine in the waiting hall of the train station is significantly higher. This is a direct reflection of the conversion of the basic quantity advantage of passenger flow into sales revenue.
（2） Stimulating consumer demand
A large number of people gather at transportation hubs, creating a consumption atmosphere that can easily stimulate travelers' desire to purchase. When people see others around them using vending machines to purchase goods, they often unconsciously generate the idea of consumption, especially when they see some products that meet their current needs or are relatively novel. For example, in the hot summer, when many passengers buy chilled drinks from vending machines at subway stations to quench their thirst, other passing passengers are also affected and more likely to stop and buy a bottle. This consumer demand stimulation effect generated by crowd gathering can further promote the growth of vending machine sales, making the positive correlation between foot traffic and sales more closely related.
3、 The foot traffic is not the only factor determining sales revenue
（1） Accuracy of product configuration
Even if the traffic flow in transportation hubs is huge, if the products in vending machines do not meet the needs of passengers, the sales volume will still be difficult to reach the ideal level. For example, in a bus station waiting hall with a majority of elderly passengers, if the vending machines mainly display trendy snacks and drinks that young people love, it may not attract most elderly passengers to purchase, resulting in limited sales. On the contrary, based on the characteristics of tourists in the region, providing some easily digestible foods, health drinks, etc. will better meet their needs, thereby increasing sales conversion rates. Therefore, the accuracy of product configuration plays a key regulatory role on the basis of foot traffic, directly affecting the level of sales revenue.
（2） The impact of competitive environment
Transportation hubs are often a stage for competition among various retail formats, in addition to vending machines, there are also convenience stores, snack stalls, and so on. If neighboring competitors offer more advantageous product prices, a wider variety of products, or higher quality services, the sales of vending machines may be impacted. For example, in the airport waiting area, if the nearby convenience store is conducting a large-scale promotional activity and the prices of goods are more favorable than vending machines, some passengers may choose to shop at the convenience store first, causing the sales of vending machines to decline. Therefore, when laying out vending machines, it is necessary to fully consider the competitive environment in which they operate, and enhance their competitiveness through differentiated management strategies to ensure stable sales growth.
（3） Optimization of shopping experience
Convenient and comfortable shopping experience is also one of the important factors affecting sales revenue. If the operation process of the vending machine is complex, the payment method is single, or there are frequent situations such as stuck goods and malfunctions, even if there is a large flow of people, passengers may give up purchasing and turn to other more reliable shopping channels. On the contrary, a vending machine with a simple interface, support for multiple payment methods, stable operation, and fast delivery will make passengers more willing to use it, thereby increasing the probability of purchase and promoting sales growth. So, continuously optimizing the shopping experience is crucial for increasing vending machine sales in crowded transportation hubs.
4、 How to increase sales through reasonable layout
（1） Site selection strategy
Accurate site selection should be based on the characteristics of different transportation hubs, such as the direction of pedestrian flow and gathering areas. At train stations, waiting halls, entrance and exit passages, and other places with high traffic and relatively long passenger stays are ideal locations for the layout of vending machines; At subway stations, emphasis can be placed on areas with frequent personnel flow, such as the two ends of the platform and transfer passages. At the same time, it is important to avoid placing vending machines in remote or obstructed corners to ensure that they can fully attract the attention of people and increase their chances of being used, thereby increasing sales revenue.
（2） Differentiated layout
Layout and product allocation based on the differentiated needs of passengers in different regions of the transportation hub. For example, in the domestic and international departure areas of the airport, different products are sold according to the different consumption habits and preferences of domestic and foreign passengers. Domestic departure areas can provide more locally distinctive snacks, souvenirs, etc; International departure areas can prepare some traditional Chinese crafts, specialty foods, etc. that are suitable as souvenirs. Through this differentiated layout, the needs of different tourist groups can be met, the targeting and attractiveness of goods can be improved, and sales can be increased.
（3） Flexible adjustment
The flow of people and passenger demand in transportation hubs are not constant. Operators need to flexibly adjust the layout position (if feasible), product types, and marketing strategies of vending machines based on seasonal changes, holiday characteristics, and fluctuations in passenger flow during different time periods. For example, during the Spring Festival, the passengers at the train station are mainly migrant workers returning home and visiting relatives and friends. It is advisable to add some suitable products as gifts; During the high temperature period in summer, increase the stock of refrigerated beverages and place them in more prominent positions. Through these flexible adjustments, better adapt to market changes and achieve maximum sales.
In summary, the layout of vending machines in transportation hubs has a close relationship between foot traffic and sales revenue. Foot traffic is an important foundation for sales revenue, but it is not the only determining factor. Operators need to consider multiple factors comprehensively, and through reasonable layout, precise product configuration, optimized shopping experience, and flexible operational adjustments, fully tap into the pedestrian flow advantages of transportation hubs, convert potential consumption into actual sales, and maximize the commercial value of vending machines in transportation hubs, providing convenient shopping services for passengers while achieving good operation and profitability.
