As anyone who has ever flown on a commercial airline since 2001 knows, security measures at airports are well enforced and the emphasis on traveller safety is all around the airport and its grounds.

Mass transportation, meanwhile, presents a special but not any less significant challenge when it comes to determining security issues. These facilities need to develop the means to protect a constantly changing and large population of passengers. And unlike airports these facilities often have hundreds of points of entry and exit on multiple modes—buses, subways, light rail, commuter trains, even ferries.
