The Technology Behind Boston's Big Dig

"After all the billions spent, all the excavation, all the concrete and sweat and steel, the opening of two major sections of the Big Dig later this year hinges on technology. It may be surprising, but this massive bricks-and-mortar project will open on time, or not, based on the readiness of systems and software that will ensure drivers' safety...The centerpiece of the Big Dig's technology budget is the Integrated Project Control System (IPCS), which could cost nearly $200 million by the time its contractor, Honeywell Technology Solutions, is done with it. This is the network of cameras, traffic-flow sensors, carbon monoxide gauges, and electronic signage, all linked to an Operations Control Center in South Boston, that will enable the Massachusetts Turnpike Authority, the state agency that oversees the Big Dig, to manage traffic and respond to emergencies."
