WSDOT SWR Traffic Management Center to CRESA Emergency Operations Center Interface Diagram

Information Flow Definitions

device identification  (Planned)  

An identifier and device type designation that is used to uniquely identify a device in the Connected Vehicle Environment.

emergency route request  (Future)  Selected Comm Solution

Request for access routes for emergency response vehicles and equipment. This may be a request for ingress or egress routes or other emergency routes. It may also include a request for preemption/priority for the identified vehicle at all signalized intersections along the route.

emergency routes  (Future)  Selected Comm Solution

Suggested ingress and egress routes for access to and between the scene and staging areas or other specialized emergency access routes.

incident information  (Existing)  Selected Comm Solution

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.

incident information for public  (Planned)  

Report of current desensitized incident information prepared for public dissemination.

incident response status  (Existing)  Selected Comm Solution

Status of the current incident response including a summary of incident status and its impact on the transportation system, traffic management strategies implemented at the site (e.g., closures, diversions, traffic signal control overrides), and current and planned response activities.

parking information  (Planned)  

General parking information and status, including current parking availability, parking pricing, and parking space availability information.

permission application  (Planned)  

A request for permission to access a Connected Vehicle service by an end–user that requires enrollment. This may include services granted to drivers of low emissions vehicles or pedestrians with special needs that require extended crossing times for example.

permission application receipt  (Planned)  

An acknowledgment that an end–user application for a Connected Vehicle service was received and processed.

remote surveillance control  (Future)  Selected Comm Solution

The control commands used to remotely operate another center's sensors or surveillance equipment so that roadside surveillance assets can be shared by more than one agency.

resource deployment status  (Existing)  Selected Comm Solution

Status of resource deployment identifying the resources (vehicles, equipment, materials, and personnel) available and their current status. General resource inventory information and specific status of deployed resources may be included.

resource request  (Existing)  Selected Comm Solution

A request for resources to implement special traffic control measures, assist in clean up, verify an incident, etc. The request may poll for resource availability or request pre–staging, staging, or immediate deployment of resources. Resources may be explicitly requested or a service may be requested and the specific resource deployment may be determined by the responding agency.

road closure notification  (Planned)  

Notification that agency personnel have closed a road due to adverse weather, major incident, or other reason.

road network conditions  (Planned)  

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 network environmental situation data  (Existing)  

Aggregated environmental situation data collected from vehicles and other sources for the road network. Aggregated information would include measured air temperature, exterior light status, wiper status, sun sensor status, rain sensor status, traction control status, ALB status, and other collected vehicle system status and sensor information for the region.

road network status assessment  (Planned)  Selected Comm Solution

Assessment of damage sustained by the road network including location and extent of the damage, estimate of remaining capacity, required closures, alternate routes, necessary restrictions, and time frame for repair and recovery.

road weather advisories  (Existing)  

Segment–specific weather and road conditions including real–time advisories of deteriorating road and weather conditions, medium–term advisories for the next 2–12 hours, and long–term advisories more than 12 hours into the future. The advisories may include advisories that are issued based on locally collected environmental data (e.g., an ice on bridge advisory).

special vehicle restricted use information  (Existing)  

Parameters necessary for implementing unrestricted access to controlled access or toll facilities by special vehicles; e.g., maintenance vehicles, emergency vehicles, etc.

threat information  (Planned)  Selected Comm Solution

Threats regarding transportation infrastructure, facilities, or systems detected by a variety of methods (sensors, surveillance, threat analysis of advisories from outside agencies, etc.

traffic image meta data  (Existing)  

Meta data that describes traffic images. Traffic images (video) are in another flow.

traffic images  (Existing)  

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. Meta data that describes the images is contained in another flow.

transportation system status  (Planned)  Selected Comm Solution

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.

wrong way vehicle notification  (Planned)  

Notification to public safety that a vehicle has been detected traveling in the wrong direction. It includes information about the vehicle (make, model, color, other identification data) and the current location, speed, acceleration, and heading of the wrong way vehicle.
