Excellent comprehensive information on safe travel from Kroll Associates, a risk management company working with international businesses, is available here.  Subjects covered include pre-trip planning, airport and airline security, taxi safety, money advice, hotel security, personal security on the street, dining and drinking, bus and train travel, health precautions, and special precautions for female travelers. We recommend that all students who are planning independent travel read this information. There is a US State Department web site that also has much helpful information.
