This paper presents an overview of the Open Mode Integrated Transportation System (OMITS), introduces its key components and algorithms in the recent development and implementation, and demonstrates the working mechanism of dynamic transit service. The OMITS has been designed to integrate the availability of multiple transit modes into the ridesharing service to provide riders and drivers flexible, efficient, and reliable transportation services, through dynamic matching and routing algorithms and emerging information communication and data mining and fusion technologies. The OMITS App, which is run on a smart phone (iPhone or Android), has been developed for customers to communicate with the OMITS server, detect roadway traffic conditions, and receive driving directions. The travel time for a road section is predicted considering the traffic factors through the historic and real-time traffic data and public transit schedule. Using the multimodal travel system, the OMITS integrates multimodal transit options including the information of time-dependent arc weights, namely travel time, and switching delays and provides the time-dependent multimodal shortest path using the Dijkstra’s algorithm under the first in, first out (FIFO) condition. The OMITS system provides an optimized ridesharing and transit service based on spontaneous transportation demands and service availability. A small scale OMITS prototype has been developed and tested in New York City. An example is presented to demonstrate the dynamic transit service algorithm.
