University role in ITS researchUniversity role in ITS research
n Current university role is subsidiaryn Universities can assist ITS to be more
transformativeo Where will the transportation funding come from?
New funding models needed.o Universities are safety leaders and safety must go
globalo Large sectors beyond “transportation” are interested
in ITS (energy, environment, sustainability); universities already have multiple interests
Current University role is Current University role is significant, yet subsidiarysignificant, 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 materialsVehicle design and performanceInfrastructure design, performance and maintenanceHighway operations and traffic modeling
a) Innovation and development
b) Demonstration and evaluation
c) Policy and standards
d) Deployment

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

IVBSS Scope and PurposeIVBSS Scope and Purposen 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 threatso 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
