Construction of Metro Smart Ticketing System Based on Location-switching Travel Determination

［Objective］ Developing smart transportation is an important focus in advancing the strategy of ′strengthening the country by building transportation power′. To enhance the convenience and intelligence levels of ticketing management and passenger services, it is necessary to establish a smart metro ticketing system. ［Method］ Based on the current operational status of Shijiazhuang Metro, existing station base station distribution data, mobile signaling data acquisition capabilities, and system data processing capabilities are utilized. By analyzing mobile signaling data and the distribution characteristics of metro system base stations, a method for determining metro travel routes based on location-switching is proposed. This method identifies and determines passenger entry, exit, interchange behaviors, and travel paths. Passenger travel recognition experiments are designed for both non-interchange and interchange scenarios to verify the technical feasibility of metro travel determination and fare calculation. Based on the experimental results, the feasibility and limitations of constructing a metro smart ticketing system based on location-switching travel determination are explored. ［Result & Conclusion］ Based on mobile signaling data and the location-switching principle, passenger travel determination and fare calculation are realized. A smart ticketing system is constructed, achieving seamless passenger gate-passing, having theoretical support, experimental validation, and technical feasibility.
