Synergies Among Congestion Pricing, ATDM, and Other Market-Based Strategies

  • Through technological advances, we have witnessed an evolution in innovative solutions designed to alleviate congestion
  • Priced Managed Lane corridors have utilized dynamic pricing as a congestion reduction strategy
  • UPA/CRD programs encouraged the use of combined strategies with the "4 Ts"
  • ICM and ATDM strategies further optimize congestion management efforts
  • Webinar presenters will focus on the synergies among these complementary strategies

Active Demand Management - Definition

Complement to:

  • Active Traffic Management
  • Active Parking Management

FHWA:

Active Demand Management (ADM) uses information and technology to dynamically manage demand, which could include redistributing travel to less congested times of day or routes, or reducing overall vehicle trips by influencing a mode choice.

Active Demand Management - Strategies

  • Dynamically managed lanes (occupancy, price. etc.)
  • Shared use mobility (e.g., carshare, bikeshare)
  • Dynamic ridesharing (carpooling and vanpooling)
  • Dynamic routing
  • Dynamic transit capacity assignment
  • On-demand transit, dynamic fare reduction
  • Transit connection protection
  • Predictive traveler information

Part B: Integrated Corridor Management

Bob Sheehan
ITS Multimodal Research Program Manager,

The Reality: Operations Today

  • Surface transportation systems are made up of several independent networks
    • Freeways, bus/rail transit, arterials, etc.
  • Most efforts to reduce congestion have focused on optimization of individual networks
    • Agency/facility/mode - specific ITS systems & strategies
  • Minimal cross-network management in response to increased demand / reduction in demand

ICM Vision

  • An opportunity exists to realize significant improvements in the efficient movement of people and goods through integrated and proactive management of major multimodal transportation corridors.

Integration

Institutional Integration - Coordination to collaboration between various agencies and jurisdictions that transcends institutional boundaries.

Operational Integration - Multi-agency and cross-network operational strategies to manage the total capacity and demand of the corridor.

Technical Integration - Sharing and distribution of information, and system operations and control functions to support the immediate analysis and response.

ICM Operational Approaches

  1. Information Sharing  / Distribution
  2. Improve Operational Efficiency at Network Junctions
  3. Accommodate (Passive) / Promote (Active) Cross Network Route and Modal Shifts
  4. Modify Capacity, Short Term - Demand Relationship Within Corridor
  5. Modify Capacity, Long Term - Demand Relationship Within Corridor

Approach D: Manage Capacity-Demand Relationship Within Corridor in "Real-time"/Short-Term

  1. Capacity Oriented
    1. Lane use control (reversible lanes / contra-flow).
    2. Convert regular lanes to "transit-only" or "emergency-only."
    3. Add transit capacity by adjusting headways and # of vehicles.
    4. Add transit capacity by adding temporary new service.
    5. Add capacity at parking lots (temporary lots).
    6. Increase roadway capacity by opening HOV/ HOT lanes/ shoulders.
    7. Modify HOV restrictions.
    8. Restrict ramp access (metering rates, closures).
    9. Convert regular lanes to "truck-only."
    10. Coordinate scheduled maintenance and construction.
  2. Demand Oriented
    1. Variable speed limits (based on Demand, Time of Day, construction, weather conditions).
    2. Modify toll / HOT pricing.
    3. Modify transit fares to encourage ridership.
    4. Modify parking fees.
    5. Variable truck restrictions (lane, speed, network, time of day).
    6. Restrict / Reroute Commercial Traffic.
    7. Incentives

KEY: Implemented at a corridor-level, multi-jurisdictional, multi-modal fashion

ICM and Pricing

  • Pricing to influence demand
  • Incentives to influence demand
  • Options
    • Modify toll / HOT pricing.
    • Modify transit fares to encourage ridership.
    • Modify parking fees.
    • Incentives.

Opportunities for integration

  • As part of an integrated approach, travelers would be given more complete information regarding their decision to pay for use of a managed lane vs. other options
  • These lanes could enhance the capabilities of ICM strategies by providing options that are already programmed and signed by regional agencies.

Challenges to Integration

  • Agencies implementing managed lanes using congestion pricing typically have a primary objective of providing a "congestion-free" option for travelers who are willing to pay.
  • Operators seek to provide a driving experience that customers perceive to be more valuable than the toll paid.
  • Ensuring travel time reliability is an important element in providing the managed lane driver with this experience, especially when compared to uncertain travel times in general purpose lanes.
  • Pricing is a powerful tool to influence demand
  • The decision to alter pricing for a corridor objective cannot be taken lightly.
  • Example: Priced facility with considerable transit service; Objective of the corridor is based on PMT and Person Delay; Major incident on general purpose lanes!!; Managed lanes will be priced to maintain maximum flow (assuming no cap);

What about the corridor objective? Should the restriction on the managed lanes be lifted? How does that affect the managed lane customer? How does that affect transit reliability and captured riders? Choice riders?

Congestion Pricing and ATDM
A Case Study of SR 167 HOT Lanes - Access Changes

Tyler Patterson
Toll Operations Engineer

Leidos Webinar February 24, 2015

SR 167 HOT lanes overview

Why HOT lanes on SR 167?

  • Highly congested route
  • Under-used HOV lanes at 2+
  • Provide drivers a choice
  • Opened May 3, 2008
  • Tolls adjust automatically to keep HOT lane traffic flowing at 45 mph or faster
  • Going on 7 years of a 4 year pilot

SR 167 HOT lanes map

SR 167 HOT lane features May 2008-August 2014

  • Free to buses, 2+ carpools and motorcycles
  • Solo drivers pay a single toll to travel any distance on 10-mile route
  • Good To Go! pass required for non- HOV
  • Single HOT lane in each direction
  • Electronic signs indicate toll rate before each entry point
  • 10 access points
  • Access Changes - HOT lane separated from general purpose lanes by single line, then double line, now single line again. Double lines are illegal to cross

Pre-HOT lanes:
SR 167 had two general purpose lanes and one HOV lane.

Traffic flow prior to HOT lanes

HOT lanes: HOV lanes were converted to a single HOT lane in each direction.

Listening to customers

"Our members have indicated that the number one complaint they have received for the SR 167 HOT Lane Pilot Program is the access control restrictions." - PSRC

"Too many drivers violating the double white line crossing restrictions without any apparent penalties. Creates a real safety hazard." - survey respondent

"We have seen already that dedicated access points can make it difficult for transit to use if not located appropriately ... a continuous access treatment would remove this uncertainty for transit." - Sound Transit

Improving SR 167 HOT lane access

$520,000 Federal Value Pricing Program grant to demonstrate more-open access on the SR 167 corridor.

Funding included:

  • Restriping and signage changes
  • Public information and outreach
  • Evaluating new access

Project goals

  • Improve access for HOT lanes drivers
  • Evaluate effects on revenue
  • Understand customer responses, attitudes and concerns
  • Determine if the new HOT lane access works

Striping changes

  • Accomplished via a design-bid-build project
  • Project duration three weeks

Work Activities

  • Remove second white stripe to create one continuous solid stripe separating the HOT toll and general purpose lanes.
  • Left double white stripe at the start and the end of the HOT lane
