Historical Perspective
• Available for 20+ years• Cost prohibitive• Difficult to maintain
• About half shut down

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
