Value Assessment of Airport Billboards Based on Passenger Big Data

As an important element of the airport ecosystem,airport billboards are playing a crucial role in publicizing the city image and facilitating humanistic airport construction.At the same time,airport billboards have great commercial value and is a popular channel for enterprises to prompt their products and to build their brand image.Currently,most airports in China adopt a simple fixed pricing mechanism for airport billboards.Specifically,for any type of billboard,the advertising price is mainly determined by considering historical prices and the total passenger flow of the entire airport during a whole year.However,this seemingly crude pricing mechanism only considers macro-level data of passenger flow and fails in reflecting the real value of billboards in different locations effectively,since the value of a particular billboard depends not only on its media form,but also on the number of passengers flowing through and whether these passengers are the target customers of the advertising content.Based on big data on airport layout,flight information,and passenger attributes,this paper proposes a time-and location-based value assessment model for airport billboards.Using sample data collected from the Beijing Capital International Airport,the assessment model is adopted to evaluate the value of two real billboards in Terminal T3.Application of this model can reflect the difference in the value of airport billboards located in different spots during various periods.Furthermore,this model provides a solid foundation for airport executives to develop differentiated/dynamic pricing and flexible advertisement scheduling strategies,thereby improving the overall efficiency.

Assessing the Influence of Roadside Advertising on Traffic Distraction and Its Interplay with Inside Vehicle Distractions: A Cross-Cultural Study in Jordan and Kuwait

Limited research has explored roadside advertisements’ effects on road user behavior in Middle Eastern countries. This study aims to understand distraction perceptions, including advertisements, their impact on behavior, and potential influences from advertisement type, in-vehicle distraction, and country factors (reflecting culture and environment). A standardized questionnaire was administered in Jordan and Kuwait, complemented by observations across three segment types: roadside advertisements, commercial signs, and road signs as control segments. Descriptive and inferential statistics were used. Results indicated a significant disparity in distraction perception between the two groups. Advertisement presence influenced Kuwaiti but not Jordanian behavior. Behavior varied by advertisement type in Jordan, not Kuwait, and in-vehicle distraction did not impact driver behavior. The study suggests explicitly revising advertising policies with a traffic safety focus. Overall, the study contributes insights into road user perceptions and behaviors, highlighting the complex interplay of distractions and advertising on road safety. Further research is required to validate these findings and shape road safety regulations.

Maximum-Profit Advertising Strategy Using Crowdsensing Trajectory Data

Out-door billboard advertising plays an important role in attracting potential customers.However,whether a customer can be attracted is influenced by many factors,such as the probability that he/she sees the billboard,the degree of his/her interest,and the detour distance for buying the product.Taking the above factors into account,we propose advertising strategies for selecting an effective set of billboards under the advertising budget to maximize commercial profit.By using the data collected by Mobile Crowdsensing(MCS),we extract potential customers’implicit information,such as their trajectories and preferences.We then study the billboard selection problem under two situations,where the advertiser may have only one or multiple products.When only one kind of product needs advertising,the billboard selection problem is formulated as the probabilistic set coverage problem.We propose two heuristic advertising strategies to greedily select advertising billboards,which achieves the expected maximum commercial profit with the lowest cost.When the advertiser has multiple products,we formulate the problem as searching for an optimal solution and adopt the simulated annealing algorithm to search for global optimum instead of local optimum.Extensive experiments based on three real-world data sets verify that our proposed advertising strategies can achieve the superior commercial profit compared with the state-of-the-art strategies.
