What can the postal service to change their business, a giant sensor network? – The Postman Always Pings Twice @ NYTimes.com

THE Postal Service recently announced it had lost $8.5 billion in the last year, despite cutting more than 100,000 jobs. Without new revenue and other changes to get it back on a firm financial footing, it said, it could face insolvency by the end of 2011.

Fortunately, the service has a unique asset that could allow it to make money by collecting valuable data that would contribute to the country’s safety and economic health: its far-reaching network of trucks.

The service’s thousands of delivery vehicles have only one purpose now: to transport mail. But what if they were fitted with sensors to collect and transmit information about weather or air pollutants? The trucks would go from being bulky tools of industrial-age communication to being on the cutting edge of 21st-century information-gathering and forecasting.

The key elements for the project already exist, including tiny, inexpensive G.P.S. receivers and radio uplinks, features found in today’s smart phones. The sensors would operate without distracting the drivers from their primary responsibilities. The service could also minimize startup costs by teaming up with a company to develop, install and operate the equipment. One company under contract with the National Weather Service is already installing environmental sensors on long-haul commercial buses to enhance weather forecasting.

The data gathered by these truck-mounted sensors would establish a baseline map of ordinary conditions, making it significantly easier to spot a problem or anomaly. Such a system could aid in homeland security by rapidly detecting chemical agents, radiological materials and, eventually, biological attacks; it could also collect detailed data to improve weather forecasts. And it could assess road quality, catalog potholes and provide early warning of unsafe road conditions like black ice.
