SPRINGFIELD, Ill. (AP) -- The state of Illinois wants public comment on transportation needs and how to make the most of limited money.

The Transportation Department plans a series of open-house events this week. The first is in Carterville on Tuesday, followed by events Wednesday in Springfield and Chicago.

The department is developing what it calls a "strategic framework for the future direction of transportation." It's supposed to address everything from highways and airports to railroads and bicycle trails. The framework is due by the end of the year.

IDOT wants people from different regions to help it with concerns like safety, the environment and planning for growth.
