1. A Future Highway Transportation System? Sources: ITS America USDOT Prof. Mike Walton, UT Austin

2. Vision for ITS The ultimate vision for the future is the transformation of surface transportation into an effectively managed, well-integrated, universally available and affordable system which: provides for the safe, secure, efficient, and economical movement of people and goods enhances customer satisfaction, and is compatible with environmental concerns

3. Key Areas Accident Prevention Accident Response Transportation Management Homeland Security Integrated Network of Transportation Information (INTI)

4. Accident Prevention Vehicle / Infrastructure Integration (VII) Cooperative systems are the next frontier Reduce severity of accidents as well as frequency Technology exists today, focus is now on deployment IVI & Telematics U.S. auto industry committed to concept

5. Accident Response Advanced Incident Management and Automatic Crash Notification New solutions exist ITS and Public Safety New stakeholders now coming to the table

6. Transportation Management Transportation System Operations & Planning More than simply building and maintaining highways ITS solutions are the key to some of the performance measurement objectives Regional coordination facilitated by ITS solutions

7. Information for Travelers Upon a query regarding a trip (such as city to city, or home to work), information is automatically assembled from multiple and overlapping data bases regarding: Modal choices Alternative portal to portal times and costs Existing or predicted congestion Work zones and construction Weather conditions Parking availability and costs Accommodations, amenities, fuel, services

8. Information for System Managers Incident detected through speed/flow anomaly Pinpointed and identified with CCTV Information instantaneously available Classification and location Commercial vehicle ID HAZMAT content ACN data Police, fire, EMS, help patrol jurisdiction, availability and location Procedural checklists Response communication/information dissemination Dispatch help patrol, wrecker, police, fire, EMS, cleanup Information dissemination Interested agencies Public and private VMS, HAR, 511, Telematics, PDAs and smart phones, Media

9. Traveler Information Current traveler information systems are dependent on limited data Probe vehicles could provide complete network information: average speeds delay weather events incidents Tailored information could be provided directly to motorists: en-route alerts congestion maps dynamic routing

10. Weather Response (Snow, Ice, Fog) 17% of all highway fatalities occur during adverse weather Weather information is critical to travelers – Gallup Survey Existing national weather information is inadequate for highway operations Efforts to enhance this information locally are expensive and of limited value Sensors on vehicles could provide could provide continuous data on air and road surface temperature, visibility, precipitation, etc. How about getting rid of the inset picture of the tree. Then the snowy road can be bigger.How about getting rid of the inset picture of the tree. Then the snowy road can be bigger.

11. Homeland Security Preparedness Prevention Protection Response Recovery

12. Homeland Security Response and Recovery: Aggressively invest in the information networks, systems and institutions to enable effective, coordinated, resilient, and dynamic management of facilities, movements and information dissemination in response to attack. Prevention: Aggressively invest in the technologies and information networks to enable identification, monitoring and tracking of mobile and non-mobile assets. Shared databases are necessary for effectiveness We already have the STRAHNET (61,000 miles) and STRAHNET Connectors (1,700 additional miles linking military installations and ports, etc. to the interstate, defense and other public highways of the STRAHNET) – we know how to deploy and have seen demonstrated value Policy deliberation and strategy development are needed regarding the appropriate scope of this activity followed by applied research and testing.

14. The INTI has three major building blocks. No one is more important than the other, and technological innovation, as we mentioned previously, is critical in all three areas. A stronger set of applications will drive better collection of data which will require better methods for sharing which will provide the opportunity for even more and newer applications – it is a circular and self-fulfilling prophecy!The INTI has three major building blocks.

15. The Safety Challenge (USA) Nearly 43,000 deaths per year from automobile accidents 3 million people injured Automobile accidents cost $230B Federal goal to reduce fatalities to fewer than 1 per every 100 million vehicle miles traveled by 2008 ITS America has established a vision for zero fatalities Most collisions in the US happen: Rear-End, Road Departure, Intersection Collision, Lane Change/Merge – these are preventable Source: US DOTMost collisions in the US happen: Rear-End, Road Departure, Intersection Collision, Lane Change/Merge – these are preventable Source: US DOT

16. Intelligent Vehicle Initiative (IVI) Reduce motor vehicle crashes by accelerating the development of driver assistance safety products

17. Major IVI Initiatives Naturalistic Driver Study Rear End Collision Avoidance System Field Operational Test Road Departure Collision Avoidance System Field Operational Test Vehicle-Infrastructure Cooperative Intersection Research

18. Intersection Collision Avoidance Intersection crashes in the US account for more than 17 % of all highway fatalities IVI Program concluded that cooperative systems were necessary to completely address intersection collisions First Intelligent Intersection demonstrated DSRC at 5.9Ghtz provides necessary capability and security

19. A New Initiative - Vehicle Infrastructure Integration (VII) Confluence of three areas…. Intelligent Vehicle Initiative – crash avoidance Emphasis on improved operations Evolution in telecommunications technology USDOT and auto companies have concluded vehicle/infrastructure cooperation is preferred for – Intersection collision prevention – Road departure prevention These 2 Account for 50% of Crashes and Fatalities on Our Roads IVI research is leading toward vehicle/infrastructure-based crash prevention technology solutions for these problems Evolution in Telecom Technology: • FCC has allocated 75MHz for – Safety Applications (1st priority) – Private Applications • DSRC Key Standards complete • FCC will rule on licensing this year (2003) • Testing new DSRC devices in 2004 USDOT and auto companies have concluded vehicle/infrastructure cooperation is preferred for – Intersection collision prevention – Road departure prevention These 2 Account for 50% of Crashes and Fatalities on Our Roads IVI research is leading toward vehicle/infrastructure-based crash prevention technology solutions for these problems Evolution in Telecom Technology: • FCC has allocated 75MHz for – Safety Applications (1st priority) – Private Applications • DSRC Key Standards complete • FCC will rule on licensing this year (2003) • Testing new DSRC devices in 2004

20. Road’s Success Developed transportation infrastructure Great at the ‘Shell Game’-Find the Car Sophisticated sensors Difficult to get required information

26. Benefits

27. Current Status Technical work is clear Deployment path is not clear “Chicken and egg” National or local (or international) Institutions do not exist to support consensus Shaping a common vision Cost and benefit alignment across industries

28. The Vision “Vehicle manufacturers and highway transportation agencies would build systems that communicate with one another to allow:” Implementation of safety features that would prevent crashes Transportation managers have full knowledge of real time operating conditions Travelers have complete information on current travel conditions Vehicle owners have access to high quality services

29. VII – There Are Issues Deployment must be nationwide Who will own, install, and operate the communications system? Who will own and operate the database? User privacy

30. The Partnership AASHTO, the USDOT and automobile manufactures have agreed to explore the opportunities presented to us by VII We have agreed that this team is vital to successfully demonstrate the possibilities in VII My role today is to explain AASHTO’s commitment and the steps we have taken.

Related projects 2005 car demonstrations other

42. Key Features Several message types: Safety (anonymous) Public data (anonymous) Private sector – services to the driver Safety has priority Data from vehicle to roadside - short term storage only “ Data cache” (anonymous) Multiple caches – probably one/two per state Integrated to form a “virtual” national cache

43. Key Features Users query cache for data User responsibility Query as often as needed Storing data Communication analysis results Technically feasible under saturation conditions

44. State / Regional Government Priorities Safety System productivity Customer service & satisfaction Security The environment Our safety tools are geometry improvements, traffic control, incident management, enforcement and education. VII may provide a new tool that can improve safety on our roadways System productivity becomes more important as congestion increases yearly. Congestion at border crossings is also becoming more important as traffic increases and security routines are implemented. How can VII play in this arena? Customer service and satisfaction can be enhanced through better information, better traffic control and better planning which may be provided through VII Security – border crossing security is important to us that have international borders like we do in Michigan. VII may have potential benefits to improve both security and the movement of freight across our borders And of course environmental stewardshipOur safety tools are geometry improvements, traffic control, incident management, enforcement and education.

45. Driving Forces: Safety

46. Driving Forces: Mobility I deleted the two notes about turning point and a new trend. Can you try to get the dashed portion of the delay line to curve more and just start to flatten out at the end of the curve. The curve should be about the same as the dotted curve you have on the fatality slide but the end should be horizontal. Does that make sense.

47. Emerging Priorities Toward Zero Deaths and Zero Injuries Eliminating Travel Delay Vehicle and Infrastructure Integration (the INTI concept) Public Safety Homeland Security

48. What Outcomes Can We Achieve? Homeland Security Travel Safety Protection of Critical and Iconic Infrastructure System Reliability and Improved Performance Improved National and Global Economic Competitiveness Improved Environment and Quality of Life

49. Information “Ownership” Each information network has multiple stakeholder and many different data “owners” e.g., the “Highway Information Network” has many stakeholders, including state/local DOT’s, vehicle operators or manufacturers, package delivery, etc – all of these groups have data pertaining to the highway Data “owners” control the functionality, quality, security, and privacy of their data In a “shared network,” stakeholders cooperate and share data to manage the system and provide value-added information to others
