TxDOT El Paso District Curve Speed Warning Systems
Status
Future
Description
Represents future curve speed warning systems. System components include roadside speed detection and warning devices to present warnings to drivers. When the speeds of approaching vehicles are above a certain threshold, the systems will provide alerts to drivers who are approaching a curve at an unsafe speed. Two types of curve speed warning system have been identified as potential solutions for the corridor: Sequential Dynamic Curve Warning Systems and Flashing Beacon Curve Warning Systems. Sequential Dynamic systems use a speed monitoring detector that triggers the illumination of LEDs outlining chevron signs in a linear sequence throughout the curve, which helps to illuminate and define the curve. Flashing Beacon systems also use a speed monitoring detector, which triggers flashing beacons on a static curve warning sign. Systems are proposed for the US–67 Corridor.

| Roadway Speed Monitoring and Warning |
'Roadway Speed Monitoring and Warning' includes the field elements that monitor vehicle speeds. If the speed is determined to be excessive, an advisory or warning is displayed. Current environmental conditions and other factors that may reduce safe operating speeds may also be taken into account. The operational status (state of the device, configuration, and fault data) is provided to the center. This application can also provide an enforcement function, reporting speed violations to an enforcement agency. |
