JAC Transit Dispatch to NDOT Headquarters Interface Diagram

Architecture Flow Definitions

current infrastructure restrictions  (Existing)  Applicable ITS Standards

Restrictions levied on transportation asset usage based on infrastructure design, surveys, tests, or analyses. This includes standard facility design height, width, and weight restrictions, special restrictions such as spring weight restrictions, and temporary facility restrictions that are imposed during maintenance and construction.

emergency transit schedule information  (Existing)  Applicable ITS Standards

Information on transit schedule and service changes that adapt the service to better meet needs of responders and the general public in an emergency situation, including special service schedules supporting evacuation.

equipment maintenance request  (Planned)  Applicable ITS Standards

Identification of field equipment requiring repair and known information about the associated faults.

equipment maintenance status  (Planned)  Applicable ITS Standards

Current status of field equipment maintenance actions.

incident information  (Existing)  Applicable ITS Standards

Notification of existence of incident and expected severity, location, time and nature of incident. As additional information is gathered and the incident evolves, updated incident information is provided. Incidents include any event that impacts transportation system operation ranging from routine incidents (e.g., disabled vehicle at the side of the road) through large–scale natural or human–caused disasters that involve loss of life, injuries, extensive property damage, and multi–jurisdictional response. This also includes special events, closures, and other planned events that may impact the transportation system.

maint and constr work plans  (Existing)  Applicable ITS Standards

Future construction and maintenance work schedules and activities including anticipated closures with anticipated impact to the roadway, alternate routes, anticipated delays, closure times, and durations.

road network conditions  (Existing)  Applicable ITS Standards

Current and forecasted traffic information, road and weather conditions, and other road network status. Either raw data, processed data, or some combination of both may be provided by this flow. Information on diversions and alternate routes, closures, and special traffic restrictions (lane/shoulder use, weight restrictions, width restrictions, HOV requirements) in effect is included.

road weather information  (Planned)  Applicable ITS Standards

Road conditions and weather information that are made available by road maintenance operations to other transportation system operators.

roadway maintenance status  (Existing)  Applicable ITS Standards

Summary of maintenance fleet operations affecting the road network. This includes the status of winter maintenance (snow plow schedule and current status).

traffic images  (Existing)  Applicable ITS Standards

High fidelity, real–time traffic images suitable for surveillance monitoring by the operator or for use in machine vision applications. This flow includes the images and meta data that describes the images.

transit and fare schedules  (Existing)  Applicable ITS Standards

Transit service information including routes, schedules, and fare information.

transit fare information  (Planned)  Applicable ITS Standards

Information provided by transit management that supports fare payment transactions.

transit fare request  (Planned)  Applicable ITS Standards

Request for fare information and transit fare payment.

transit incident information  (Planned)  Applicable ITS Standards

Information on transit incidents that impact transit services for public dissemination.

transit probe data  (Existing)  Applicable ITS Standards

Aggregate probe data derived from tracking transit vehicles. Data collected could include transit vehicle speeds and travel times for a given link or collection of links.

transit schedule adherence information  (Existing)  Applicable ITS Standards

Dynamic transit schedule adherence and transit vehicle location information.

transit system data  (Planned)  Applicable ITS Standards

Current transit system operations information indicating current transit routes, the level of service on each route, and the progress of individual vehicles along their routes for use in forecasting demand and estimating current transportation network performance.

transit trip plan  (Planned)  Applicable ITS Standards

An origin–destination transit trip that may involve multiple modes and connections.

transit trip request  (Planned)  Applicable ITS Standards

Request for a transit trip plan that is responsive to traveler requirements such as schedule, cost, or duration.

trip confirmation  (Planned)  Applicable ITS Standards

Acknowledgement by the driver/traveler of acceptance of a trip plan with associated personal and payment information required to confirm reservations.

work plan feedback  (Existing)  Applicable ITS Standards

Comments and suggested changes to proposed construction and maintenance work schedules and activities. This information influences work plan schedules so that they minimize impact to other system operations and the overall transportation system.

work zone information  (Existing)  Applicable ITS Standards

Summary of maintenance and construction work zone activities affecting the road network including the nature of the maintenance or construction activity, location, impact to the roadway, expected time(s) and duration of impact, anticipated delays, alternate routes, and suggested speed limits. This information may be augmented with images that provide a visual indication of current work zone status and traffic impacts.
