The Memphis police force, which covers 315 square miles with more than 2,000 officers, responded to about 1 million calls last year. With such heavy volume, the department can go from call to call without necessarily seeing the bigger picture, Janikowski said.

Siemens, based in Munich, created a division called infrastructure and cities this year to help it win contracts to improve transport networks and provide electronics for buildings. Chief Executive Officer Peter Loescher aims to boost revenue from municipalities to get him closer to a goal of achieving 100 billion euros ($134 billion) in sales.
