Historical Perspective
• Available for 20+ years• Cost prohibitive• Difficult to maintain
• About half shut down
10-3-12 Net Zero through Emerging Technologies 15
Example Deployment
• 2.5 mile, 4 lanes, 12 signals• 26,000 vpd
• Annual savings– 95,000 hrs travel time– 34,000 gal fuel– 9,000,000 stops– $2.5 million economic benefit
• Tech cost vs. construction cost
10-3-12 Net Zero through Emerging Technologies 16
Benefits
• Long term optimization/results• Waste reduced (time, fuel, emissions)• Sustainability (move more cars on
the same pavement)
