Since Sept. 11, 2001, trucking technologies first embraced for productivity gain are now being looked to for security.

Technology Editor John Bendel looks at how technology will enhance homeland security in the cover story of the April issue of Heavy Duty Trucking.
Using satellite tracking and other mobile communications technology for security is not new; Qualcomm notes that its customers in Brazil have been using its OmniTracs system primarily for security for years, protecting cargo from thieves and hijackers.
But satellite tracking systems, including newer trailer tracking systems, are not the only technologies being touted as security measures. Mapping and routing software can work hand in hand with tracking to make sure the truck is routed properly to avoid possible security threats and to monitor it to make sure it doesn't deviate from the route.
RFID (radio frequency identification) may become a public policy concern, because both public and private RFID networks are growing rapidly with little compatibility between them. Yet some experts predict that RFID will increasingly be in demand to verify the identities of trucks and drivers at critical points in the transportation system.
