Abstract: To help those domestic passengers who are not familiar with the use of the Internet and foreign passengers to use self-help railway ticketing services smoothly, an optimization scheme of self-help ticketing services of Beijing-Zhangjiakou high-speed railway is proposed. On the basis of the existing automatic ticketing system, the remote assistance and interaction server is added and the design of the automatic ticket vending machine and the passenger service staff’s terminal are optimized by improving their user interaction interface, thus enabling those passengers to directly communicate with the passenger service staff for convenient access to information consultation and remote assistance. The composition of the self-help ticketing service system, the hardware composition of the automatic ticket vending machine and the service terminals as well as function design of the system are described and key technologies used in the implementation of the system, such as voice&video calling, signaling control, call queuing and remote desktop control, are summarized. At present, the system and its equipment have been put into operation in Beijing-Zhangjiakou high-speed railway and good practical results of its application have been achieved.
