Today’s Exercise
(Part 2) High Impact Apps
  • As we did yesterday, consider up to 10 applications in each impact area
    • One slide per concept, brief clarifying discussion
    • Record High-Medium-Low rating on your scorecard for each of the measures
  • 3-2-1 Poker chip voting for the applications most likely to have transformative impact (per your measures)
  • Facilitated discussion about the application with the highest vote total
    • Identify key data, communications and research needs for this application
    • How close to transformative will this application get us?
  • Repeat facilitated discussion for second highest ranked application
    (time permitting)
  • Reconvene to consider results within each breakout
    • Discuss the implications of your group process
    • Identify a presenter from your group for the breakout report at 11 AM
5
Exercise Ground Rules
  • For today’s exercise, these items can’t be changed
    • Breakout group impact area definitions
    • No adding new application concepts
  • Data environment assumptions from yesterday can be relaxed, however
    • Assumptions about what data is available can be tailored in this exercise
  • Policy-related issues are NOT in play for discussion
    • Intellectual Property, Privacy, Access/Security, Meta-data, Quality, Aggregation, Standards, Financial/Business Models….
    • If these topics come up, we will park the discussion until this afternoon, when we have special session to deal with these in turn

Application Evaluation Criteria
  • Next, we’re going to go through application concepts that address the environmental impact area
  • We will present each concept on a single slide
    • You can ask clarifying questions, or offer suggestions about how data might be leveraged
    • But the concept itself cannot be altered, modified or enhanced in discussion
  • Record an notes/comments on each application with an assessment on your scorecard for each criteria (High-Medium-Low)
    • Let’s fill in our selected measures now on your scorecard
  • Consider how you will vote for the applications with the most potential to achieve our transformative targets
    • What applications have the most potential to help us reach our transformative target by 2025?

Application #1:
SPD-HARM
  • Dynamic Speed Harmonization
  • Problem Addressed:
    • Improve throughput and reduce risk of collision by optimizing for lane-specific speed limits on a freeway facility
  • Description
    • Monitor traffic and weather data captured from multiple sources, and calculate a target speed for vehicles
    • Target speeds may be advisory or enforced, and may vary by location, e.g., distance upstream of a recurrent bottleneck, and by lane
    • Communicate target speeds through overhead dynamic signage, via DSRC to enabled vehicles with range (I2V) and from vehicle to vehicle (V2V)


11
Application #2:
ECO
  • Connected Eco Driving
  • Problem Addressed:
    • Improve fuel economy and reduce emissions by improving driver awareness of local road topography, signal status, and weather condition.
  • Description
    • Modify vehicle operation to improve fuel economy and reduce emissions considering grade, predicted speed changes or braking, and real-time traffic
    • Adapts based on driver aggressiveness, energy/fuel consumption, brake regeneration, engine/drive torque-speed characteristics, other factors
    • Provide feedback to the driver (or electronic control signals to semi-autonomous systems) to keep the vehicle operating in target range


12
Application #3:
ICM
  • IntelliDrive-Driven Integrated Corridor Management
  • Problem Addressed:
    • Incompatible operational and data collection procedures limit coordination among freeway, signal system, and transit system operators in a corridor
  • Description
    • Aggregate, consolidate and exchange data on alternate routes and modes to provide true corridor-wide traveler information services
    • Enable traffic management and transit agencies to coordinate their existing systems to improve corridor performance
    • Support integrated and coordinated response during major incidents and emergencies within corridor boundaries


13
Application #4:
RAMP
  • IntelliDrive-Driven Ramp Metering System
  • Problem Addressed:
    • Improve current ramp metering systems capability to respond to changing traffic conditions in real time
  • Description
    • Leverage new mobile source data to calculate optimal ramp metering rates resulting in improved throughput and reduced emissions
    • Broadcast timing information (analogous to SPaT data) allowing vehicles to decelerate or accelerate
    • Integrate with HOV bypass, arterial signal coordination and dynamic speed harmonization applications deployed in same interchange


14
Application #5:
D-RIDE
  • Dynamic Ridesharing
  • Problem Addressed:
    • Logistical constraints of traditional carpooling (e.g., long-term commitments, fixed schedules, and communication difficulties) prevent ridesharing from realizing its full potential
  • Description
    • Leverage in-vehicle and hand-held devices to allow ride-matching
    • Integrate carpooling functions into vehicle computer and displays, use voice activated ridesharing technology to reduce distraction effects
    • Vehicle-data integration utilized by HOV/HOT enforcement agencies to verify vehicle occupancy


15
Application #6:
I-SIG
  • IntelliDrive-Driven Traffic Signal System
  • Problem Addressed:
    • Improve the accuracy and timeliness of data used to control signal systems, reducing delays, costs and emissions while improving travel reliability
  • Description
    • Utilize data from vehicles to accurately predict lane-specific platoon flow, platoon size, and other traffic characteristics
    • Reduce time and cost barriers to updating traffic signal timings, both periodic and real-time updates
    • Consider (freight/transit/light) vehicle mix in signal timing plans


16
Application #7:
SIG-FLOW
  • Adaptive Speed Control for Efficient Traversal of Intersections
  • Problem Addressed:
    • Address under-utilization of the space-time resource within an intersection, reducing delays and improving emissions
  • Description
    • Vehicles with adaptive cruise control coordinate with intersections
    • Each vehicle is assigned just the amount of space-time needed within the intersection to enable safe passage by an intersection manager agent
    • Target vehicle speeds through the intersection managed by an in-vehicle driver agent, although the driver may over-ride


17
Application #8:
T-DISP
  • Dynamic Transit Operations
  • Problem Addressed:
    • Traditional fixed route/fixed schedule transit is inherently inefficient for the traveler in low density, low ridership, and dispersed origin/destination areas
  • Description
    • Enable demand-responsive transportation services utilizing GPS and mapping capabilities of mobile devices
    • Travelers input a desired destination and time of departure tagged with their current location
    • Central system dynamically schedules and dispatches or modifies the route of an in-service vehicle by matching compatible trips together
    • Like a stock exchange, providers can bid/trade within a transparent platform

Breakout Exercise
(Part 2) Voting
  • Now that we’ve worked through all the applications,
    vote for the three most promising applications
    • BLUE = 3 points (top priority)
    • RED = 2 points (second-highest priority)
    • WHITE = 1 point (third-highest priority)
    • Deposit your chips in the voting bins identified for each application
      (also turn in your scorecards)
  • We’ll take a quick break (5 minutes) to tabulate the results
  • One Bin, One Participant, One Chip rule
    • Do NOT dump all of your chips in a single bin
    • We want your individual priority of the top THREE applications
