Interface: TxDOT Houston TMC - TxDOT Houston Variable Speed Limits
Information Flow Definitions
environmental sensor control (Future)
Data used to configure and control environmental sensors.
environmental sensor data (Future)
Current road conditions (e.g., surface temperature, subsurface temperature, moisture, icing, treatment status) and surface weather conditions (e.g., air temperature, wind speed, precipitation, visibility) as measured and reported by fixed and/or mobile environmental sensors. Operational status of the sensors is also included.
roadway dynamic signage data (Future)
Information used to initialize, configure, and control dynamic message signs. This flow can provide message content and delivery attributes, local message store maintenance requests, control mode commands, status queries, and all other commands and associated parameters that support remote management of these devices.
roadway dynamic signage status (Future)
Current operating status of dynamic message signs.
traffic detector control (Future)
Information used to configure and control traffic detector systems such as inductive loop detectors and machine vision sensors.
traffic detector data (Future)
Raw and/or processed traffic detector data which allows derivation of traffic flow variables (e.g., speed, volume, and density measures) and associated information (e.g., congestion, potential incidents). This flow includes the traffic data and the operational status of the traffic detectors
variable speed limit control (Future)
Information used to configure and control variable speed limit systems including the equipment used to provide current speed limits and other information to drivers.
variable speed limit status (Future)
Current operating status of the variable speed limit systems including the state of the equipment.
