What are Managed Lanes?
A facility that increases freeway efficiency by packaging various operational and design actions

Vehicle Occupancy
User must “declare” their occupancy Occupancy requirements can change:
by time of day by facility by access point
User may change occupancy by trip Managing Occupancy = Enforcement Occupancy enforcement poses
challenge to revenue leakage

Driver must declare HOV or SOV by lane selection
HOV’s on outside help enforcement and accuracy of tag readers
Passing would be prohibited at gantry No additional tag technology

Managed Lane Policy
High-occupancy vehicles of two or more occupants will receive a 50 percent discount during the peak period Not just as easy as SOV pay and
HOV free More complex for different prices
for SOV, HOV2, HOV3+

Managed Lane Policy (cont.)
Market-based tolls will be applied during the dynamic-pricing phase Market-based pricing
No caps Give operator ability to maintain desired
operating speed Dynamic pricing
San Diego and Minneapolis currently have dynamic pricing
Technology to gather managed lane and general purpose lane conditions

Managed Lane Policy (cont.)
During the dynamic-pricing phase, travelers will receive rebates if the average speed drops below 35 mph (fault of the operator) What or how much is the rebate? Delivered to individuals, the project, or
the region? Based on individual or average speeds? Delivered in real-time or post trip?

Summary
Managed lanes will increasingly be used as a corridor management tool
Technology is critical to all aspects of managed lanes Variability in pricing & occupancy pose
the biggest challenges Continue to Build on Current
Technology Industry Needs Cost Effective
Occupancy Enforcement
