  • FHWA's ATDM Program

Slide 3

SECTION 1: DEFINING ACTIVE MANAGEMENT AND THE ATDM CONCEPT

Slide 4

Characteristics of an Actively Managed Operations Culture

  • Focuses on now rather than the future
  • Recognizes conditions vary and may not be "typical"
  • Orients toward customers and their service needs
  • Focuses on performance outcomes not outputs
  • Emphasizes managing rather than development
  • Exists as a 24/7 service, not a 9-5 office
  • Scales to trip – not just a jurisdiction

Slide 5

What is Active Management?

The fundamental concept of taking a dynamic approach to a performance based process

Illustration of the Active Management Cycle which includes monitoring the system, assessing system performance, evaluating and recommending dynamic actions, and implementing dynamic actions.

Slide 6

Moving Towards Active Management

Illustration that shows that Transportation Agency Operations typically takes a stair step approach to increased Active Management. The first step is static management, the second step is responsive management, and the third step is proactive management.

Slide 7

Moving Towards Active Management: Shoulder Use Example

Flow chart walking audience through the different levels of active management from static to reactive and then to active management.

Slide 8

Goal of ATDM Concept

  • Attain the capability to dynamically monitor, control, and influence travel, traffic, and facility demand of the entire transportation system and over a traveler's entire trip chain.

Slide 9

ATDM Throughout the Trip Chain

Illustration showing how ATDM addresses demand across the entire trip process in a dynamic manner. The key takeaway is that active management occurs before, during, and at the end of the trip chain. The trip chain refers to all of the choices travelers make in getting from their origin to their destination and includes mode, designation, route, and time.

Slide 10

What does ATDM include?

Active Demand Management (ADM): A suite of strategies intended to reduce or redistribute travel demand to alternate modes or routes Incentivizes drivers by providing rewards for traveling during off peak hours with less traffic congestion.

Active Traffic Management (ATM): A suite of strategies that actively manage traffic on a facility.

Active Parking Management (APM): A suite of strategies designed to affect the demand on parking capacity.

Examples of ATDM Implementation Strategies
ADM Comparative multi-modal travel times, dynamic ride-sharing, pricing, and incentive approaches.
ATM Variable speed limits, dynamic shoulder use, queue warning, lane control.
APM Parking pricing, real-time parking availability and reservation systems.

Slide 11

The ACTIVE and INTEGRATED Continuum

Graph showing four quadrants of the active and integrated continuum with the Y axis labeled Active and the X axis labeled Integrated. The four quadrants include Early in Active and/or Integrated Operations; Active, but not Integrated; Active and Integrated; and Integrated by not Active. The desired end state is Active and Integrated.

Slide 12

Integrated Corridor Management (ICM)

  • ICM is the joint management of a transportation corridor as a complete system
    • Load balancing
  • Corridor operates at optimal performance, given the available capacity of each network
    • ATDM needed to realize vision
Illustration of integrated corridor management (ICM) of freeway, arterial, rail, and transit systems within a corridor.

Slide 13

ATDM Relationship to ICM

  • ICM is built on the fundamental concepts of load balancing.
  • ATDM approaches need to be applied to realize the vision of ICM

Slide 14

Active Management in a Corridor

Slide 16

Scope Varies by Agency

Scale of Implementation
(site-specific to regional)
Illustration of the scale of implementation starting from the smallest to the largest as site-specific, facility, corridor, and regional.

Types of Implementation
(ADM, ATM, APM or a combination)
Illustration of the four types of implementation. The far left sphere is Active Traffic Management with examples listed as adaptive ramp metering and variable speed limits. The top sphere is Active Demand Management with an example of dynamic ridesharing. The far right sphere is Active Parking Management with examples of dynamic pricing and dynamic parking reservation. The middle sphere is ATDM Implementation.

Slide 18

Active Demand Management Example: Mobile Applications

Innovative Mobile Traffic Apps:

  • Goal: manage demand by influencing driver choice over a longer period of time
  • How: Encourage behavior change through incentives (e.g., bigger rewards during off-peak travel)
  • What: Real-time trip predictions, route mapping, voice navigation and pre-trip alerts
