Reach Targeted Audiences AudienceThematic Outreach Materials Technical staff and local officials Technical content with emphasis on facts, benefits, and experiences of other communities Local public officials Less technical content with accent on ramp metering benefits and safety Law enforcement (highway patrol) Focuses on ramp metering operation and enforcement General public Highly graphic, non-technical, and focuses on the need for ramp metering

22. After Study One year study Scout will release a six month update Rush hour accident reductions are the primary goal Improved mobility (reductions in travel time) are secondary

23. Summary and Conclusion Why do KDOT and MoDOT want to implement ramp metering? City concerns and government education Law enforcement Customer inquiries
