Now, almost everyone has access to a mobile device, and with latest generation mobile devices the possibilities for offering new information services are endless. However, the existing navigation systems providing services and information on the city's traffic are not real-time, complete and the localized information may be not "customized" enough. Moreover, the services should be more user friendly, more efficiently and dynamic. Therefore, in this paper we present a Customized Navigation Systems with Mobile Devices of Public Transport based on our life. To accomplish these goals, our systems separate three sub-systems to implementation. The systems open up new opportunities for delivering quality public transport services, achieve minimize the passengers' cost, and user can tag or write note in map creating a own map, providing location-based services for users to help those in unfamiliar areas and real-time updates and improve operational practice; they contribute towards "greener travel choices" by making public transport easier to understand and therefore more convenient.
