At Affinis, we have the talent and expertise in-house to take your traffic project from start to finish. Developing concepts and analyzing alternatives to create cost-effective designs is something we do very well. Our traffic team is skilled at analyzing data in existing and proposed conditions and then, developing geometric and system improvements to increase safety and expedite traffic.

Whether we’re completing studies or designing solutions, our traffic engineering team looks for ways to make our client and the public’s lives easier with effective design.

The City of Leawood needed the signal design at 133rd and Roe fast tracked. Affinis delivered quality plans in six weeks and provided excellent communication throughout the process.
