2 Hardware Manufacturers Target AudienceSoftware DevelopersHardware ManufacturersService ProvidersEducatorsThis presentation will discuss the various elements of highway engineering automation and propose full utilization of information rich 3D point cloud data - beyond the project and into the life cycle management of the highway corridor.
4 Future Transportation a peek into the future5 minutes
5 Future Transportation Issues Expected Problems:Possible Solutions:Increased TrafficIncreased CongestionIncreased Carbon EmissionsIncreased Fuel CostsAging Driver - SafetyAging InfrastructureUrban GrowthIncrease Mass TransportationDevelop Alternative FuelsReduce Need for MobilityIncrease Highway CapacityDevelop Smart Cars and HighwaysRe-think the meaning of
6 Imagine the Year 2037 More Highways? More Lanes? Faster Vehicles? Safer Vehicles?Smarter Vehicles?Smarter Highways?Self Driving (autonomous) Vehicles?“If I would have asked my customers what they wanted, they would have said…a faster horse.”Henry Ford

11 Tomorrow’s Vehicles …Autonomous Advanced Positioning and Navigation Lane TrackingNight Vision AssistObstacle/Pedestrian DetectionDedicated Short Range Communications (DSRC)Highway to Vehicle CommunicationVehicle to Vehicle CommunicationSituation Awareness Beyond Capabilities of Human Driver…Autonomous
12 Autonomous Vehicles Will not take away human control Reduce driver workloadReliance on on-board sensorsReliance on knowledge of highway geometryCombination of sensors and highway geometry
14 Autonomous Vehicle Reality Nevada Governor Signs Driverless Car Bill Into Law – June 2011Provides that the Nevada Department of Motor Vehicles "shall adopt regulations authorizing the operation of autonomous vehicles on highways within the State of Nevada.“Setting safety and performance standardsRequires designated areas where driverless cars may be tested.

22 Engineering Automation The Next Twenty Five Years… New ParadigmData-centricReal-time InformationCollaborative EngineeringHighway Infrastructure Lifecycle ManagementAutomated ConstructionIntelligent Vehicles and Highwayswill be…All About Information!
23 To Enable This Future Paradigm, we need: To accept disruptive technologiesA complete transformation.To redefine the nature of our work, how it’s conducted, and what we consider final products.To demand standardized data formatsTo collaborate across government agencies and private businessesA “Disruptive Technology” is one that requires changes to long standing established processes.
