Recently, the launch of "ride hailing buses" in cities such as Shijiazhuang and Handan in Hebei Province has attracted social attention. Citizens can book and choose their own starting and ending points through the mobile mini program, and then "take" the bus at the regular bus fare within the designated area. This innovative model that integrates the flexibility of ride hailing services and the inclusiveness of public transportation provides new ideas for the development of urban public transportation. Online ride hailing buses "match dispersed and dynamic travel demands with idle bus capacity in real time, breaking the traditional" fixed-point, fixed route, and timed "operation mode of public transportation and achieving a transformation from" people waiting for buses and people looking for routes "to" cars looking for people and routes following people ". Its value is reflected in multiple aspects. For citizens, many new areas and suburbs have insufficient coverage of conventional buses and high taxi costs. "Online ride hailing buses" have improved travel convenience with their universality and convenience; For managers, optimizing transportation capacity configuration through intelligent scheduling is expected to improve service quality while activating existing resources and reducing empty driving rates. As a new phenomenon, "ride hailing buses" still need to be continuously explored and improved on the road from pilot to popularization. The first issue is the balance between efficiency and inclusiveness. Since it is carpooling, it is inevitable for vehicles to take detours to meet the needs of different passengers. How to control the detour time within an acceptable range and ensure the travel efficiency of the majority of passengers through optimization algorithms and intelligent scheduling while ensuring inclusiveness is the key to maintaining its attractiveness. Next is the challenge of sustainable operation. In the future, exploring a business model that balances public service attributes with sustainable operation requires joint efforts from relevant government departments, enterprises, and society. In addition, it is necessary to design rules and clarify its positioning in the entire urban public transportation system - as a "beneficial supplement" to conventional buses and subways rather than a substitute, forming a pattern of benign complementarity and differentiated development with taxis, ride hailing services, etc. The "ride hailing buses" have shifted public transportation services from a "flood irrigation" style to a "precision drip irrigation" style, which is a beneficial exploration to promote public service reform. We welcome and encourage such innovative attempts, and look forward to continuous optimization of operational strategies and improvement of technical support in practice, so that "ride hailing buses" can run more steadily and farther, truly becoming a new choice for convenient travel for the masses.
