Status of ITS research May 6 2010 Peter Sweatman sweatman@umich.edu David Kapp

University role in ITS research n Current university role is subsidiary n Universities can assist ITS to be more transformative o Where will the transportation funding come from? New funding models needed. o Universities are safety leaders and safety must go global o Large sectors beyond “transportation” are interested in ITS (energy, environment, sustainability); universities already have multiple interests
3
Current University role is significant, yet subsidiary Universities have the capability to cover a) through c) at least Driver attention, response, behavior and attitudes are critical – major current university role – major data resources with minimal analysis Developing technologies and materials eg. wireless, cellular, sensors, intelligent materials Vehicle design and performance Infrastructure design, performance and maintenance Highway operations and traffic modeling a) Innovation and development b) Demonstration and evaluation c) Policy and standards d) Deployment
4
Researching the components of the system n Drivers (2) o We don’t understand how people drive n Vehicles (7) o Safety, advanced modeling, sensors, situational awareness n Infrastructure (4) o Traffic operations, asset management, safety, ITS n Information technology (9) o Mobile devices, networks n Energy/environment (5) o Powertrains, fuels, electrification, smart grid Intelli Drive

5 IVBSS Scope and Purpose n A 5 year effort to develop and field test integrated safety systems for passenger vehicles and heavy trucks n Safety systems will provide warnings for rear- end, lane change and road departure crashes in addition to arbitration of multiple crash threats o Forward crash warning, lane departure warning, lane change/merge warning, curve speed warning n Includes a one-year field test on public roads to determine system performance, safety benefits, and user acceptance

Fuel economy Unemployment Price of gasoline The system we have now Historic reduction of 9000 fatalities We don’t know where the levers are
13
Carbon dioxide 1/Fuel economy Distance driven -12% -8%
14
Fatalities Distance driven
15
“System” data is at a primitive stage n Safety is trying to change human behavior in critical situations o Design of the interface between driver and technology n Avoiding unintended consequences n Setting standards o Minimum performance standards o Ratings o While technology rapidly evolves n Measuring effectiveness o Crash studies o Near-crash studies (eg. SHRP 2) o Warning rates from driver assist systems
16
Video Current Data Visualization
17
As we move to a system with defined end states and variables n This will be a complex system o Discontinuities, tipping points n We will need open data systems, not only for developers and entrepreneurs but also for to monitor the system state o Unintended consequences
