On-Time Performance is a critical measure for transit agencies. Yet, there are still missing opportunities for improving on-time performance. Transit agencies can improve the delivery of services by using data from Intelligent Transportation Systems (ITS). Different ITS technologies are currently being used. However, there is still the need for specialized software applications to fully leverage ITS data. This paper presents a method for using a web-based service to monitor on-time performance real time. It uses Automatic Vehicle Location data and a web service that publishes a dataset directly from the database. An extended service is also included for additional functionality. The paper describes the methodologies for the data management and reporting services. Skype is used to notify transit staff automatically when the on-time performance for the whole system or a particular route is below a desired threshold. This is a proactive approach to improving OTP, rather than acting on reports after the fact. A case study conducted using data from Miami-Dade Transit (MDT) is also presented in this paper. The methodology used and the findings from this research can be applied by transit agencies to help improve operational efficiencies and quality of service.
