EN-ROUTE TRANSIT INFORMATION SYSTEMS: THE STATE OF THE ART IN NORTH AMERICA

En-route transit information systems (ERTIS), which provide information to travelers using public transportation after they begin their trips, are in the process of being designed, developed, and implemented in several locations across North America. These systems are based on several advanced public transportation systems (APTS) technologies, most importantly, automatic vehicle location (AVL) technology. Even though these APTS technologies are mature and proven, the techniques used to process real-time information for presentation to the transit customer are not. Most of the activities in North America to develop ERTIS highlight the uncertainty in developing techniques and algorithms that result in accurate and reliable information. The purpose of this paper is to describe the state of the art in ERTIS in North America, emphasizing the issues associated with providing accurate and reliable information to the customer. The paper will briefly describe existing and planned ERTIS, the technologies being used to implement the ERTIS, and the issues associated with ERTIS implementation. Since ERTIS can provide information on-board vehicles in key loactions, such as transit centers and intermodal facilities and at transit stops, there is a wide variety of systems being planned and implemented in North America. Also, since these systems provide information that can include real-time arrival and departure information, real-time connection/transfer information, information on other regional transportation services, and fare, schedule, and route information, there are many techniques being proposed to transform raw real-time data into useful customer information.
