VII Day-1 Applications and MDSS Pat Kennedy Road Weather Management Program Federal Highway Administration Maintenance Decision Support System (MDSS) Annual Stakeholders Meeting August 11, 2006

2 VII VII (Vehicle Infrastructure Integration) is a USDOT/FHWA sponsored initiative aimed at developing and deploying a nationwide integrated communications infrastructure that supports both vehicle-to-vehicle and vehicle-to-infrastructure communications Development of Day-1 applications will be used to help define and refine what this network will look like on the first day it becomes operational

3 Application development Twenty “Day-1” applications have been selected for development by members of the VII Working Group and a variety of other Subject Matter Experts. Application selections were based on a number of factors: –Meeting high priority safety, mobility, and commerce needs –Need to be achievable within acceptable timeframes –Provide some early benefit to users and operators –Achievable with low penetration of VII-equipped vehicles –Providing the ability to test the system and assist the decision making process

4 Day-1 applications #NameLead 1Emergency Brake WarningCAMP 2Traffic Signal Violation WarningCAMP 3Stop Sign Violation WarningCAMP 4Curve Speed WarningVIIC 5Display Local SignageVIIC 6Present OEM Off-Board Navigation VIIC 7Present OEM Reroute InformationVIIC 8Present Spontaneous Traffic Information VIIC 9Electronic Payments: Parking / General VIIC 10Electronic Payments: Gasoline VIIC #NameLead 11Electronic Payment: Toll RoadsUSDOT 12Traveler InformationUSDOT 13Ramp MeteringUSDOT 14Signal Timing OptimizationUSDOT 15Pothole DetectionUSDOT 16Winter MaintenanceUSDOT 17Corridor Management Planning Assistance USDOT 18Corridor Management Load BalancingUSDOT 19Weather Information Traveler NotificationUSDOT 20Weather Information Improved Weather Observing USDOT

5 Day-1 application #16: Winter Maintenance PURPOSE: Provide additional environmental and surface condition information to the management functions responsible for winter maintenance on our nation’s roadways GOALS: Collect environmental data from multiple vehicle sensors Process this data into MDSS, thereby: –Improving real-time surface condition information provided to transportation operators and managers –Improving the accuracy of predictive forecasts for route specific surface conditions and associated treatment recommendations

6 Examples of VII probe sensor data and derived meaning(s) Onboard Vehicle SenorDerived Information Date time stampTimeframe GPS vehicle locationVehicle location, altitude and direction Vehicle speedTraffic data/implied surface conditions Wiper system statePrecipitation detection Exterior air temperatureEstimated ambient temperature Infrared temperature sensor (  )Pavement surface temp (non-snow covered) Plow blade position (  )Surface treatment information Chemical type selection (  )Type of chemical applied Chemical application (  )Whether a chemical is being applied Chemical application rate (  )Amount of chemical applied Antilock brake statusPavement surface state Traction control statusPavement surface state Vehicle stability controlPavement surface state Steering inputsPavement surface state Steering inputs & accelerometer outputsDeduced vehicle skid Steering inputs w/wo accelerometer outputsSnow accumulation on the road Heater/defroster stateNature of precipitation, visibility index, etc. Window washer stateVisibility index, road conditions

7 Examples of VII/MDSS generated messages to onboard maintenance vehicle displays Mobility phrases (and associated color) displays GOOD MOBILITY REDUCED MOBILITY CAUTION! SLIPPERY ROAD SURFACE DANGER! VERY SLIPPERY ROAD SURFACE Treatment phrases REDUCE NACL TO 100 LBS/LANE MILE INCREASE NACL TO 250 LBS/LANE MILE RECOMMEND ANTI-ICING OPERATIONS RECOMMEND PLOW ONLY OPERATIONS

8 Winter Maintenance Concept of Operations Winter Maintenance has been chosen as one of the first four Day-1 applications for which a Concept of Operations is going to be developed Tasks will include: - Developing an initial draft for stakeholder review - Conducting an initial web-meeting with stakeholders - Hosting an industry workshop - Completing a final Con Ops for Winter Maintenance Estimated completion timeframe – Jan/Feb 2007

9 VII Schedule & Phasing Development Phase Concept of Operations Proof of Concept Application Development Infrastructure Deployment (Phase 1) Infrastructure Deployment (Phase 2)
