WSDOT SWR Traffic Management Center to Other Transit Operations Center Interface Diagram

Information Flow Definitions

alternate mode information  (Existing)  

Schedule information for alternate mode transportation providers such as air, ferry, and passenger–carrying heavy rail. This also includes details of incidents and other service disruptions that have occurred in the alternative mode. This also includes measures of service demand that supports assessment of their impact on the road network.

device identification  (Planned)  

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

emergency transit schedule information  (Planned)  Selected Comm Solution

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.

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  (Existing)  

Report of current desensitized incident information prepared for public dissemination.

parking information  (Existing)  

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.

road network conditions  (Existing)  

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.

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.

transit and fare schedules  (Existing)  

Transit service information including routes, schedules, and fare information. This also includes on–demand service information.

transit incident information  (Existing)  

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

transit probe data  (Existing)  Selected Comm Solution

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)  

Dynamic transit schedule adherence and transit vehicle location information.

transit service information  (Existing)  

Transit service information including routes, schedules, and fare information as well as dynamic transit schedule adherence and transit vehicle location information.

transportation operational strategies  (Existing)  Selected Comm Solution

Operational strategies for each operating agency in a transportation corridor, downtown area, or other travel–impacted area, providing an integrated operations strategy for the freeways, tollways, arterials, transit services, parking facilities, and other transportation–related facilities in the area. These strategies can include dynamic adjustments to transit fares and tolls, parking fees and restrictions, dynamic lane restriction changes, and other active demand management strategies.
