Core Viewpoint - The transformation of highway service areas reflects a shift in development concepts, driven by the integration of transportation and tourism, as well as rising consumer expectations for travel experiences and public services [1][2]. Group 1: Policy and Development - In 2017, the Ministry of Transport and five other departments issued guidelines to promote the integration of transportation and tourism, encouraging the addition of various services in highway service areas, such as leisure, logistics, ticketing, tourism information, and local product sales [1]. - Several distinctive service areas have been recognized as demonstration cases for the integration of transportation and tourism, accelerating the process of this integration [1]. Group 2: Demand and Supply Dynamics - The shift in travel structure has led to a rise in self-driving trips, with small passenger vehicles accounting for over 90% of total traffic during major holidays, making service areas a new entry point for traffic [1]. - Service areas are evolving from traditional models of "gas station + restroom + convenience store" to a new model of "service area + tourism," aiming to convert traffic into sustained visitor engagement [1]. Group 3: Future Expectations - With the largest domestic tourism market and highway network globally, there is an expectation for more highway service areas to become cultural stages, engines for industrial development, and boosters for regional economies through continuous innovation and quality upgrades [2].
