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

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
