In modern life, everyone needs to reach their destinations in time. For people who rely on the public bus transportation requires to get the reliable bus information that can help them to reduce their waiting time at the bus stops. In the age of digital transformation, smart phones, laptops, other digital devices are changing the world very day lives. Among them, GIS is one of the players. In a modern urban region, public transportation network such as bus, train, taxi and etc. are become so large that why passengers lack sufficient information. In order to solver that we will app that will guide user shortest route to reach the destination. In this paper, we will use GIS and Dijkstra’s Algorithm to calculate the shortest path. The system is implemented using free and open source technologies including open source GIS tools. A prototype application is designed and implemented based on short distance bus routes in Yangon city bus routes.
