A study of bus location system using LoRa: Bus location system for community bus “Notty”

The information terminal bus stop has been studied widely. It is reported that the information terminal bus stop for citizen support is effective for the purpose of improving citizens' convenience. In particular, the bus location system is considered important for the purpose of eliminating users' concern about what time will it arrive?, Will it arrive at all?; thus, there is a great deal of research. Because conventional systems need the communication charges, there are problems including introduction and maintenance costs are high. Therefore, a method using Wi-SUN has been proposed. However, Wi-SUN has a short transmission distance characteristic and requires many repeaters. The problem of introduction cost has not been solved. In order to solve this problem, we propose a bus location system using LoRa. The proposed system was able to reduce the number of the repeaters and bus stops to 1/4 or less compared with the system using Wi-SUN. The proposed system is superior to the system using Wi-SUN in terms of installation cost.
