Interface: City of Chicago DOT TMC To Illinois Gateway

request for road network conditions   (Planned)  

Request for traffic information, road conditions, surface weather conditions, incident information, and other road network status. The request specifies the region/route of interest, the desired effective time period, and other parameters that allow preparation of a tailored response. The request can be a subscription that initiates as-needed information updates as well as a one-time request for information.

 

road network conditions   (Planned)  

Current and forecasted traffic information, road and weather conditions, incident information, and other road network status. Either raw data, processed data, or some combination of both may be provided by this architecture flow.

 

traffic control coordination   (Planned)  

Information transfers that enable remote monitoring and control of traffic management devices. This flow is intended to allow cooperative access to, and control of, field equipment during incidents and special events and during day-to-day operations. This flow also allows 24-hour centers to monitor and control assets of other centers during off-hours, allows system redundancies and fail-over capabilities to be established, and otherwise enables integrated traffic control strategies in a region.

 

traffic information coordination   (Planned)  

Traffic information exchanged between TMC’s. Normally would include incidents, congestion data, traffic data, signal timing plans, and real-time signal control information.
