Spatio-temporal Information in Intelligent Transportation Systems Ouri Wolfson Bo Xu University of Illinois, Chicago

Miniscule impact of IT on travel experience Routing Real-time public transport (e.g. bus-tracker) Autonomous driving Fleet Management Software Car navigation systems (payment for info)

3 Why? Distributed/mobile system of unprecedented scale Incentive mechanisms / business models Conservative community

4 Intellidrive A V2V, V2I, V2D communication infrastructure that will provide information about all roads all the time

5 Intellidrive (VII): A Federal Initiative Vision Integrated system of Billions of mobile and static sensors to enable a broad range of safety and mobility services Approach –Convene a “VII Coalition”— auto manufacturers, state transportation authorities, USDOT— to work through issues in the technical, policy, business models, Source: FHWA

6 Safety applications make a driver aware of unforeseen vehicles, road conditions, and hazards: –Vehicle in front has a malfunctioning brake light –Vehicle on crossroad is about to run a red light –Patch of ice at milepost 305 –Vehicle 100 meters ahead has suddenly stopped

7 Efficiency/convenience/mobility applications on-route traffic and weather conditions, –What is the average speed a mile ahead of me? –Is the upcoming pavement wet there? –Are wipers/fog-lights on there? –Are there any accidents ahead? gas station location and prices, parking availability and prices, transit vehicle on-time performance –What taxi cabs are there around me? –Multimodal trip planning and execution. Optimization by time, distance, cost

8 Analogy: Infrastructure => Entrepreneurship - 15 years ago, the advent of the internet/WWW fostered New –companies, –Products –Services Most couldn’t be foreseen when internet infrastructure established - Vehicle communications will foster similar growth New –companies, –Products –Services

Research Issues

10 IntelliDrive Applications Platform Develop a platform for building applications –A software architecture –Interfaces –Tools –Services that enables easy application-development Analogy: Internet (IntelliDrive) and WWW (CTS platform)

Routing, Navigation, Tracking Up-to-the-minute –travel time and –incident information –Involves information search, stream management, integration Data models and optimization criteria –Multiple modes such as train, bus, car, bicycle –Minimize (exposure to) pollution –Optimal routes when everyone has up-to-minute congestion info?

Other IT research issues Abstraction of concepts from spatio- temporal sensor data streams (semantic location activity inference) Mobile P2P data management –Query processing in MANETs –Bandwidth and energy constraints Social networks and crowd-sourcing
