Highway Vulnerability Assessment Overview

2002 AASTHO Guide to Highway Vulnerability Assessment was developed for State DOT officials to examine critical assets carefully and identify cost-effective countermeasures to provide better protection against the threats of terrorism involving the use of weapons of mass destruction (WMD).

It uses:

• Asset data
• - National Bridge Inventory System
• − Hazardous Materials Information System
• Threat data
• − Law Enforcement
• − State’s Emergency Management Agency
• − Homeland Security Office
• Vulnerability data
• - Consequence data
• - Countermeasures data
• - Cost data
• - Policies, plans, and procedures
• - Personnel (interviews)
• - Geographic Information systems (maps, drawings)

It is a six step process.
