How does a Work Zone Intrusion Alarm system enhance safety for workers inside an active buffer space?

1. It automatically deploys steel spike strips into open traffic lanes.
2. It projects laser beams onto oncoming driver windshields to blind speeders approaching the zone.
3. It shuts off all vehicle engines within a 500-foot radius automatically.
4. It senses errant vehicles crossing the taper and sounds a high-decibel audible alarm.
