Workzone Intrusion Prevention Chris May, VP of Safety and Environmental Operations

Started Early for Me

The Challenge Reduce the number and severity of accidents in work zones – Protect workers, members of law enforcement, pedestrians and the traveling public Maintain safe and efficient flow of traffic through work zones – Adjust the traffic control plan/devices to extend beyond the plans and specifications based on specific risk(s) identified by contractor. (example: congestion, public confusion, excessive speed, visibility issues, etc.)

The Statistics Highway and street construction workers are at risk of fatal and serious nonfatal injury when working in the vicinity of passing motorists, construction vehicles, and equipment. Each year, more than 100 workers are killed and over 20,000 are injured in the highway and street construction industry.

An effective internal traffic control plan (ITCP) informs all parties operating within the work space about the location of others. It creates zones designed to minimize interaction between workers on foot and construction vehicles/equipment. An ITCP should: – Reduce the need to back up equipment – Limit access points to work zones – Establish pedestrian-free areas where possible – Establish work zone layouts commensurate with type of equipment – Provide signs within the work zone to give guidance to pedestrians, equipment and trucks – Design buffer spaces to protect pedestrians from errant vehicles or work zone equipment Internal Traffic Control Plan (ITCP) aka Vehicle / Pedestrian Segregation Plans for Work Zones

This is our “WHY” Best practices haven’t been enough because we still suffer serious and fatal injuries Remember those statistics about 100 workers being killed a year? These are our reasons for the need to find for a better method of protection. Frank Chet Bubba MarshallRonaldo

Actual Alert (internal) A light tower truck can be seen entering the work zone at 26.7 mph and advancing directly toward the crew. As indicated by the alert code in the subtitle text, both a WorkTrax and a flashing light alert were activated to warn the crew and motorists. In response to the warning, the motorist exited the work zone and the alert stopped.

Actual Alert (external) In the video, a black SUV (confused driver) approaching at 27 mph is first detected at 508 feet from a roller. At 498 feet, the AWARE system issued a WorkTrax alert to notify the roller operator of the intrusion. After the WorkTrax alert, the roller operator monitored the vehicle and the SUV slowed and exited the work lane at 256 feet from the roller at under 10 mph. As a result of the decreased speed, the vehicle did not trigger the light and siren alerts.
