provided by this architecture flow. Information on diversions and alternate  
routes, closures, and special traffic restrictions (lane/shoulder use, weight  
restrictions, width restrictions, HOV requirements) in effect is also included.  
Transit operations information including schedule and fare information. The  
request can be a subscription that initiates as-needed information updates as  
well as a one-time request for information.  
transportation system status  
traveler information for media  
Current status and condition of transportation infrastructure (e.g., tunnels,  
bridges, interchanges, TMC offices, maintenance facilities). In case of disaster  
or major incident, this flow provides an assessment of damage sustained by  
the surface transportation system including location and extent of the damage,  
estimate of remaining capacity and necessary restrictions, and time frame for  
repair and recovery.  
General traveler information regarding incidents, unusual traffic conditions,  
transit issues, or other advisory information that has been desensitized and  
provided to the media.  
traveler profile  
traveler request  
trip plan  
Information about a traveler including equipment capabilities, personal  
preferences and recurring trip characteristics.  
Request by a traveler to summon assistance, request information, make a  
reservation, or initiate any other traveler service.  
A sequence of links and special instructions comprising of a trip plan indicating  
efficient routes for navigating the links. Normally coordinated with traffic  
conditions, other incidents, preemption and prioritization plans.  
trip request  
Request by a driver/traveler for special routing.  
vehicle based information_ud  
Vehicle information transmitted from on-board vehicle equipment used as part  
of VII effort to communicate between vehicles and traffic management centers  
via roadway equipment.  
vehicle messages_ud  
video images_ud  
Vehicle messages used as part of VII effort to communicate with the on-board  
equipment.  
High fidelity, real-time video images suitable for surveillance monitoring by an  
operator.  
video surveillance control  
violation notification  
Information used to configure and control video surveillance systems.  
Notification to enforcement agency of a violation. The violation notification  
flow describes the statute or regulation that was violated and how it was  
violated (e. g., overweight on specific axle by xxx pounds or which brake was  
out of adjustment and how far out of adjustment it was). A violation differs  
from a citation because it is not adjudicated by the courts.  
weather information  
Accumulated forecasted and current weather data (e.g., temperature,  
pressure, wind speed, wind direction, humidity, precipitation, visibility, light  
conditions, etc.).  
work plan coordination  
Coordination of work plan schedules and activities between maintenance and  
construction organizations or systems. This information includes the work plan  
schedules and comments and suggested changes that are exchanged as work  
plans are coordinated and finalized.  
work plan feedback  
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.

Architecture Flow  
Description  
work zone information  
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.  
work zone status  
Current work zone status including current location (and future locations for  
moving work zones), impact to the roadway, required lane shifts, expected  
time(s) and duration of impact, anticipated delays, alternate routes, and  
suggested speed limits.  
work zone warning notification  
work zone warning status  
Notification of a work zone emergency or safety issue. This flow identifies that  
a work zone emergency or safety issue has occurred so that warnings may be  
generated by more than one system in the work zone.  
Status of a work zone safety monitoring and warning devices. This flow  
documents system activations and includes additional supporting information  
(e.g., an image) that allows verification of the alarm.
