C-TIP Real Time Traffic Monitoring (RTTM) and Dynamic Route Guidance (DRG)

1. C-TIP Real Time Traffic Monitoring (RTTM) and Dynamic Route Guidance (DRG) In association with: Talking Freight Seminar November 17, 2010 Paul Belella

2. Agenda • Project Overview • RTTM & DRG Concept • RTTM Overview • DRG Overview • RTTM & DRG Functional Layout • RTTM & DRG Operation • RTTM & DRG Schematic • Important Factors

3. Project Overview • Primary Objective: Make tailored real-time traffic information and route guidance available to motor carriers to mitigate congestion and reduce delay • Major Project Components • Design and Development of RTTM Module • Design and Development of DRG Module • Implementation of both in Kansas City • Connection with C-TIP • Two of several components • Fully integrated with other modules • Scalable and transferable to other locations

4. RTTM & DRG Concept Smart Phone En-route Truck Commercial Cellular Network Roadway Traffic Data RTTM/DRG

5. RTTM Overview • Telemetry Processor • Receive telemetry data • Locate trucks on routes • Traffic Interfaces • Receive traffic information from KC Scout & Navteq • Calculate link speeds and travel times • Traffic Report Generator • Formulate trip-specific travel time reports • Use of current travel time calculations • IMEX/WDU Interface • Receive requests • Forward travel time info for dissemination to trucks

6. DRG Overview • Primary Objective: Extend the RTTM functionality to provide navigation information to help trucks avoid congestion and minimize travel time • Approach • Calculate “best route” from location to destination • Build on RTTM and WDU applications and devices • Leverage latest in dynamic routing research and practical applications • Integrate fully with C-TIP

8. RTTM & DRG Operation • Throughout Trip: • Device reports • Location • Heading • Speed • Device requests travel info • Visual display is locked out for safety Alternate Route #2 Alternate Route #1 • At Decision Points: • 3 miles from re-route point • Device requests travel info • RTTM/DRG execute trip calculations • Primary route • Alternate routes • RTTM/DRG advise about shortest trip (audio notification only) Primary Route • At Origin: • Driver enters destination • Driver requests travel info • RTTM/DRG execute trip calculations • Primary route • Alternate routes • RTTM/DRG advise about shortest trip

10. Important Factors • Collecting the right data • Multiple sources (trucks, roadway sensors, etc.) • Accurate depiction of current conditions on roads of interest • Packaging data into useful information • Designed to properly interpret the data available to it • Formulating information that can be confidently acted upon • Making information available when it is needed • The intended use underscores importance of timeliness • End users will need to interpret the information and formulate decisions quickly

11. Important Factors • DRG provisioning requirements • Accurate input data (reliable travel time/speed reporting) • Timely input data (low data latency) • Reliable historic data (for comparison to current data) • Rapid alternatives calculation (for quick response to user requests) • Predictive travel time modeling (to compensate for changes during trip) • Accommodation for roadway limits (i.e., restricted routes, geometric constraints, clearances) • Significant challenges • Validating DRG output • Providing useable output to drivers • Accommodating human behavior variables • Getting truckers to trust DRG recommendations
