CASE STUDIES

Case Study: Curve Warning System

WisDOT Prevents In-Curve Accidents With Warning System

Discover how the Wisconsin Department of Transportation saw a 97% decrease in accidents after installing the BlinkerChevron™ Dynamic Curve Warning System.

“We have also installed [this curve warning system] on two-lane roads, and they have been very successful in reducing crashes.”

activation

ACTIVATION OPTIONS

24/7 OPERATION

Programmed to always flash the system, 24/7 operation provides added safety at interstates and highly trafficked curves.

24/7 operation of the LED-enhanced curve warning system

DUSK 'TIL DAWN

Using ambient light sensors, BlinkerChevron™ flashes during nighttime hours to enhance awareness.

TIME CLOCK

The programmability of the time clock provides traffic engineers with the ability to schedule system activation during specific timeframes.

  • Operated via PC or web-enabled devices
  • Ability to schedule activations up to two years in advance
Time Clock programming schedules system activation times

RADAR DETECTION

Radar sensors are mounted on the first system pole to trigger the system to activate based on predetermined criteria:

  • Vehicle Activated - Triggers system activation when vehicle approaches curve
  • Speed Activated - Triggers system activation when vehicle exceeds predetermined speed threshold and can adjust speeds based on vehicle classification
  • Speed With Classification Activated - Triggers system activation when vehicles approaching the curve are exceeding the predetermined speed for their vehicles’ classification
Radar detection activates the system to warn drivers of dangerous situation

arrangement

ARRANGEMENT OPTIONS

SINGLE-SIDED

One chevron per pole to alert drivers approaching the curve. Installed on roads where drivers travel in only one direction, such as interstates and highways.

Single-Sided Chevron

DOUBLE-SIDED

Two chevrons per pole installed on roads where drivers travel in both directions, such as two-lane rural roads.

TECHNOLOGY UPDATE

New design lowers the total cost of ownership and provides:

  • Simplified install and commission process
  • 25% reduction in power consumption allowing for more solar panel options
  • Enhanced system connectivity

SYSTEM ENHANCEMENTS

ADVANCE CURVE WARNING ALERTS

Integrate Advance Curve Warning Alert to this system to provide advance warning of changes in road trajectory with customized signs and advisory speed plaques.

IN-ROAD WARNING LIGHTS

Embedded in the pavement, to outline and emphasize the curve, In-Road Warning Lights (IRWL) flash in unison to alert drivers of the change in direction.

MESSAGE BOARDS

Blank out Signs - Display warning messages and flash overhead beacons when drivers are traveling too fast for the curve.

Dynamic Message Boards - Provides en-route information that adjusts to a warning when the driver is traveling too fast for the curve ahead.

ROAD WEATHER INFORMATION SENSOR

Precipitation sensor triggers system activation and adjusts speed threshold when unfavorable weather conditions are present based on predetermined specifications.

CONNECTED VEHICLE INTERFACE

Add another layer of safety to your system with the Connected Vehicle Interface, an Ethernet interface for TAPCO BlinkerCheveron™ Dynamic Curve Warning Systems to connect with and communicate information to connected vehicle infrastructure, such as Road Side Units.

BLINKLINK POWERED BY TAPCO

Enhance this system with BlinkLink powered by TAPCO, an easy-to-use, cloud-based software application for agencies to remotely manage and monitor their Intelligent Warning Systems.
