Today’s Exercise
(Part 2) Voting
  • Once you have scored each application, each participant votes for the three most promising applications
    • “Most promising”: strong potential for transformative impact, low deployment risk, and clear alignment with IntelliDrive program objectives
    • 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)
  • Quick break (5 minutes) to tabulate the results
  • 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 3 PM

Exercise Ground Rules
  • For today’s exercise, these items can’t be changed
    • Evaluation criteria
    • Data Environment assumptions
    • Application concepts (no altering or adding new ones)
  • Policy-related issues are NOT in play for discussion

Application Evaluation Criteria
  • Next, we’re going to go through application concepts that utilize data from the arterial data environment
  • 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
    • Please record notes or comments on each concept on your scorecard
  • You rate each application on three criteria (High, Medium, Low)
    • Potential Impact: will this application have transformative impact?
    • Deployment Readiness: if we assume the data is available, can this application be developed, tested and widely deployed by 2025?
    • Program Alignment: does the application align with program objectives and is there a clear federal role in its development and deployment?
12
Application #1:
CACC
  • Cooperative adaptive cruise control
  • Problem Addressed:
    • Significantly improve throughput by increasing capacity and efficiency, and increase safety by minimizing the number of interactions between vehicles
  • Description
    • A traffic manager sets a gap policy to form or break-up platoons of vehicles
    • Speeds are automatically adjusted by the vehicle based on communications from the traffic management center
    • Ad hoc or managed platoons of vehicles moving on the arterial
    • Management of gaps, flows and arrival rates
    • Systematically accounts for differing vehicle weight and performance


13
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


14
Application #3:
FSP
  • Freight Signal Priority
  • Problem Addressed:
    • Reduce delays and improve travel time reliability for commercial vehicles traversing signalized corridors with significant truck traffic
  • Description
    • Give priority to freight vehicles at intersections near key facilities (ports, rail terminals, warehouses, distribution centers)
    • Signal timings may be adapted to dynamically changing commercial vehicle demand at intersections, or along the entire facility
    • Enhances safety and reduces environmental impacts on these facilities by reducing congestion and excessive idling


15
Application #4:
PED-SIG
  • Mobile Accessible Pedestrian Signal System
  • Problem Addressed:
    • Many legacy pedestrian signals at traffic signals are not accessible to pedestrians with visual impairments, auditory systems have drawbacks
  • Description
    • Mobile devices carried by visually impaired pedestrians receive SPaT data broadcast in signalized intersections
    • Orients intersection and crosswalk geometry, as well as intersection status
    • Mobile devices also broadcast messages to make enabled vehicles aware that a pedestrian is present in the case of blocked line-of-sight


16
Application #5:
CURB-PKG
  • Curbside Parking Availability System
  • Problem Addressed:
    • Inform drivers about the availability of curbside parking, reducing congestion, emissions, and driver frustration
  • Description
    • Monitor curbside parking availability either by using fixed sensors installed in parking meters or the road surface, or by a network of connected vehicles
    • Parking data relayed to a central manager for processing and broadcast
    • Inform travelers in real time the availability of parking spaces, the rate, type, and hours via the internet as well as mobile and in-vehicle devices


17
Application #6:
PREEMPT
  • Emergency Vehicle Preemption with Proximity Warning
  • Problem Addressed:
    • Reduce congestion and risk of accidents for motorists and pedestrians resulting from emergency vehicles traversing multiple arterial intersections
  • Description
    • Adjust preemption and signal recovery cycles to account for non-linear effects of multiple emergency responses
    • Broadcast proximity warnings as the vehicle traverses the facility
    • Support location-specific signage, alerts, and warnings to motorists and pedestrians of immediate emergency vehicle operations


18
Application #7:
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


19
Application #8:
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


20
Application #9:
GSP
  • General Road User Traffic Signal Priority
  • Problem Addressed:

    • Generate revenue on traditionally non-revenue generating roadways


21
Application #10:
TSP
  • Transit Signal Priority
  • Problem Addressed:
    • Due to a limited ability to make accurate predictions, traditional methods have resulted in poorly performing TSP schemes
  • Description
    • Enable earlier detection of buses, and more accurate and continuous monitoring of the bus as it traverses the corridor
    • Establish low latency and ongoing communications with Priority Request Servers (PRS) at individual, or multiple, intersections
    • Consider new inputs (e.g. passenger loads) and criteria (e.g. type of service, peak direction, etc.) for generating priority requests


22
Application #11:
WX-INFO
  • Real-Time Route Specific Weather Information for Motorized and Non-Motorized Modes
  • Problem Addressed:
    • improve mobility and safety of users of motorized and non-motorized modes of transportation (e.g., automobiles, transit, freight, bicyclists, and pedestrians) by providing real-time, highly localized weather information

    • 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)

  • 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

Results Discussion
  • Were similar or dissimilar applications selected during voting?
  • Did the highest ranking applications align in the same quadrants of the impact/deployment readiness chart?
  • Regarding the top 6 applications:
    • Are they highly overlapping?  Or independent?
    • Do they require coordinated research?
    • Will they require coordinated deployment?


  • Who would like to volunteer to report out the breakout group findings?
