Interface: DDOT TMC - Local Traffic Control Centers

DDOT TMC to Local Traffic Control Centers Interface Diagram

Architecture Flow Definitions

current asset restrictions  (Planned)  Applicable ITS Standards

Restrictions levied on transportation asset usage based on infrastructure design, surveys, tests, or analyses. This includes standard facility design height, width, and weight restrictions, special restrictions such as spring weight restrictions, and temporary facility restrictions that are imposed during maintenance and construction.

maint and constr work plans  (Planned)  Applicable ITS Standards

Future construction and maintenance work schedules and activities including anticipated closures with anticipated impact to the roadway, alternate routes, anticipated delays, closure times, and durations.

traffic control coordination  (Planned)  Applicable ITS Standards

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 images_ud  (Planned)  

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 the operational status of the surveillance system.

traffic information coordination  (Planned)  Applicable ITS Standards

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