On-board Fixed Route Schedule Management Equipment Package

 Architecture Geographic Scope

Description:

 Collecting of data for schedule generation and adjustment on-board a transit vehicle. Supports communication between the vehicle, operator, and center.

 

Included in:

 Independent School District Buses
The Connection Vehicles

Functional Requirements:

1The transit vehicle shall receive transit route information for its assigned route including transit service instructions, traffic information, road conditions, and other information for the operator.
2The transit vehicle shall use the route information and its current location to determine the deviation from the predetermined schedule.
3The transit vehicle shall calculate the estimated times of arrival (ETA) at transit stops.
4The transit vehicle shall determine scenarios to correct the schedule deviation.
5The transit vehicle shall provide the schedule deviations and instructions for schedule corrections to the transit vehicle operator if the deviation is small, or the transit vehicle is operating in an urban area.
6The transit vehicle shall send the schedule deviation and estimated arrival time information to the center.
7The transit vehicle shall support the operations of a flexible route service. This may include requests for route deviations that would then lead to schedule corrective actions.
  

User Service Requirements (fully or partially addressed):

2.0PUBLIC TRANSPORTATION MANAGEMENT
2.1.0ITS shall include a Public Transportation Management (PTM) function.
2.1.1PTM shall include an Operation of Vehicles and Facilities (OVF) function that provides computer assisted control of the operation of vehicles and their associated facilities.
2.1.1.2OVF shall include a Command and Control (CC) capability.
2.1.1.2.1CC shall provide the capability for real-time Vehicle Command and Control (VCC).
2.1.1.2.1.1VCC shall provide the capability to compare received information with predetermined operating condition specifications and note any deviations.
2.1.1.2.1.3VCC shall provide the capability to display any noted deviations.
2.1.1.2.1.4VCC shall provide the capability to automatically issue corrective instructions to the operator including, but not limited to, the following:
2.1.1.2.1.4(a)Route corrections.
2.1.1.2.1.4(b)Changes in stops.
2.1.1.2.2When CC detects a vehicle(s) has deviated from schedule it shall provide the capability to automatically determine the optimum scenario for returning the vehicle or fleet to schedule.
2.1.1.2.4CC shall include the capability for its computational capabilities to be located either on-vehicle and/or at remote locations.
