1. Concept of Operations

The following specification describes an Intelligent Transportation System (ITS) and has been designed for use by rural or small urban paratransit transportation providers. Specifically, it provides a passenger the ability to schedule a demand/response bus trip to a designated location or activity. The passenger will contact a dispatch center to schedule the trip. The dispatch operator will receive information from the passenger such as name, address, telephone number, etc. as well as the destination of the bus trip. The dispatch operator will then enter the passenger information into a scheduling software package. The software will provide a report identifying the bus and time the passenger will be picked up. The dispatch operator will notify the passenger with all the information about the trip. On the day that the trip is scheduled, the passenger will arrive at the scheduled time and pick up point to wait for the bus. When the bus arrives, the passenger will board the bus and be greeted by a message that says, “Good Morning, Mrs. Chavez. This is Bus # 3”. The passenger will know that they are on the correct bus. The passenger will then be taken to the scheduled drop-off point and arrangements made for the return trip – if not previously scheduled.


2. Scope

This specification includes all of the components and software needed to install, integrate and operate an ITS system as well as technical specifications identifying the operating parameters of each component. This document also includes specifications on equipment for the dispatch center, onboard the vehicle, and interfacing with the customer.

As referenced in Advanced Public Transportation Systems: State-of-the-Art Update 2006, the specifications address the areas assembled in the Transit ITS typology classification.
