Gateway Traveler Information System GTIS to Illinois Tollway TMC (TIMS) Interface Diagram

Architecture Flow Definitions

device control request  (Existing)  Applicable ITS Standards

Request for device control action

device data  (Existing)  Applicable ITS Standards

Data from detectors, environmental sensor stations, roadside equipment, and traffic control devices, including device inventory information.

device status  (Existing)  Applicable ITS Standards

Status information from devices

emergency traffic coordination  (Planned)  Applicable ITS Standards

Coordination supporting disaster response including evacuation and reentry. Includes coordination of special traffic control strategies that support efficient evacuation and reentry while protecting and optimizing movement of response vehicles and other resources responding to the emergency.

fare and price information  (Planned)  Applicable ITS Standards

Current transit, parking, and toll fee schedule information.

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.

logged vehicle routes  (Existing)  Applicable ITS Standards

Anticipated route information for guided vehicles, special vehicles (e.g., oversize vehicles) or groups of vehicles (e.g., governor's motorcade) that may require changes in traffic control strategy.

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 network traffic situation data  (Planned)  Applicable ITS Standards

Aggregated route usage, travel times, and other aggregated data collected from probe vehicles that can be used to estimate current traffic conditions.

traffic counts  (Existing)  

Traffic counts from fixed or mobile traffic sensors.

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.

traveler information  (Existing)  

Traveler information provided to a 511 type phone system.
