Chicago wants a slice of the action in self-driving cars.

In an office tower in the city’s West Loop, Nokia Corp. has 300 people working on technology that will help cars talk to one another, as well as to traffic signs, smartphones and other devices.

Elsewhere in greater Chicago, more than 50 engineers are working on connecting vehicle entertainment and navigation systems to phones, tablets and the cloud at a new Harman International Industries Inc. research center.
