Work Zone SafetyIs Everybody’s Responsibility

Work Zone SafetyIs Everybody’s Responsibility

Every year more than 600 people lose their lives in work zone accidents. One moment can save a life — when driving in a work zone, slow down and pay attention to the road.

SWZSWZ

FDOT is leveraging ITS and CAV technologies to create

SWZ projects.

SWZ concept will be tested a future interstate

resurfacing, construction, or widening on projects.

Purpose

To develop an implementable SWZ Pilot concept for an upcoming construction and future

project.

Goal

Improve safety and travel time reliability for motorists and construction personnel in and around work zones.

Utilizes ITS, CV and emerging technologies to improve safety and mobility in work zones:

REAL TIME: Data collection and analysis in real time, providing frequently updated information to motorists.

PORTABLE: Portable system allowing its installation at different locations.

AUTOMATED: Maximum automated operations for efficiency and reducing human operators.

Connected Arrow Boards (CAB)

▶CAB is an advance warning traffic control device used at lane closures to navigate vehicles through work zones

▶Allows fast reaction to emergencies and aids in performing routine maintenance

▶Sends real-time data to information providers to display up-to-date navigation information for drivers

▶Alerts motorists via navigation system (e.g., Waze)

▶Help reroute traffic away from work zones

▶Allows navigation through active work zones safely and quickly

States Using Connected Arrow Boards

► MINNESOTA DOT - equips arrow boards with the functionality to export status and location for stationary and mobile/rolling closures. (2018)

► NEW JERSEY DOT - Smart arrow board project to examine the effectiveness of

iCones technology on service patrol vehicles. (2018)

► NEVADA has focused on relaying lane closures through iCones “Smart Arrow Board” modification product. (2017)

► NORTH CAROLINA DOT - instructs the flashing arrow boards to transmit

information about location, direction, and which lane is closed. The RFP was

issued on April 16, 2019 and requested “Connected Lane Closure Devices.” The

initial connected device shall be designed and attached to the flashing arrow

board.

Posts GPS Location and ‘Arrow Panel Status’ to XML feeds for access by transportation departments and major navigation data services

▶Upon Activation of the Arrow Panel: • Transmits location and ‘ON’ status. • LEFT/RIGHT/DOUBLE arrows (Static Arrow, Moving Arrow, Sequential Arrow, Sequential Chevrons). • CAUTION (Flashing Corners, Flashing Line, Alternating Diamond).• Status posted to XML within 2 minutes.• Transmits Arrow Panel status every 15 minutes. • Re-transmits location and status if the Arrow Panel moves more than 300 ft.

▶ Upon De-Activation: • Transmits location and ‘OFF’ status. • Status posted to XML within 60 seconds.• Updates location and ‘OFF’ status at four-hour intervals.

▶ Reporting: • XML or JSON posting for agency data centers.
