1 The I-35 Connected Work Zone Robert E. Brydia, PMP Senior Research Scientist

2 National Freight Corridors Freight corridors move +$16T goods annually +14B tons of freight annually Expected to rise to 19B by % of corridors are responsible for moving 80% of goods

3 Texas Freight Corridors $1.4T in freight value (2014) 1 billion tons (2014) 90% projected heavy truck VMT growth ( ) 44% of Texas workers in a freight dependent industry I-35 is largest TX freight corridor

4 FRATIS Solutions (General) Freight-Specific Dynamic Travel Planning and Performance Enhances traveler information systems to address specific freight needs Integrated data Real-time information and dynamic routing Drayage and Truck Routing Optimization Optimize truck/load movements Individual trucks are assigned best time windows for pick up or drop off Bi-Directional Communication Mechanism Adaptive communication among all stakeholders (e.g., motor carriers, drivers, MTOs, and BCOs) Provide real-time status updates

5 Background: FRATIS Problem Statement (USDOT) The lack of Freight Advanced Traveler Information has a negative effect on: Efficient movement Planning of freight daily activities Logistics management systems Environment of neighboring communities Energy consumption Safety of the traveling public

6 Trip Planning Origin: UP-San Antonio Intermodal Terminal Destination : BNSF-Alliance (Cutoff Time: 5:30 PM) Distance: 298 Miles Estimated Travel Time: 4 hrs. 31 min. Departure: 11:30 AM Estimated Arrival Time: 4:01 PM (Planned) Lane Closure Actual Arrival Time: 5:50 PM From 12:00 AM to 3:00 PM Trip Delay 1 hr. 49 min. (40%) Average Speed: 40 mph Missed the cut-off time Unexpected Delay: 25 min. Delay in delivery to Customer New Estimated Arrival Time: 4:56 PM Equipment-related fines Lower driver productivity Lower efficiency Road Construction Higher carbon footprint From 10:00 AM to 5:00 PM Average Speed: 35 mph Unexpected Delay: 30 min. New Estimated Arrival Time: 4:31 PM Traffic Incident Average Speed: 40 mph Unexpected Delay: 20 min. New Estimated Arrival Time: 5:51 PM Traffic Congestion From 2:00 PM to 5:00 PM Average Speed: 30 mph Unexpected Delay: 35 min. New Estimated Arrival Time: 5:31 PM Current State Limited or No Data

8 FRATIS I-35 Corridor Optimization for Freight Optimize freight flow on 1-35 corridor Phase 1 Utilize 1-35 Traveler Information During Construction (135TIDC) system for high-quality traffic and construction data Cust.om optimization software prov1ded to carriers

9 Optimization Algorithm Enhancement Process Added Constraints Waiting Times at Marine Terminal Real Time Traffic provided by Navteq Added Constraints Customized based on integration with TMW Order Management System Version 7: FRATIS Central Florida Added Constraints Network T rahic Patterns Real Traveling Time provided by INRIX and T MC Receiving Docks Schedules Added Constraints: Integration with 1-35 Traveler Information System developed by TTl ~

10 Phase 1 Freight Corridor Optimization Current and future lane closures Average speed and travel times Real-time Historical Optimization routine (dispatcher level) Cab-based tablets with schedules Expected benefits: More robust plans using real travel times and expected delays due to construction activities

11 Integration with I35TIDC FRATIS will be integrated with the components of I-35 TIDC system to integrate high-quality traffic and construction data into the optimization process. CDCS PCNS LCAS Corridor Data Collection Subsystem average speed and travel Planned Closure Notification Subsystem current and future lane closures Lane Closure Assessment Subsystem prediction of queues and delays due to closures Determine the best dispatching time and delivery schedule for trucks to adapt with the traffic flow on the I-35 corridor according to the dynamic changes from construction activities

14 What Went Wrong with Plan A??? Large carriers Already have technology and optimization (Don t need gov t help!) Loss of capability Inability to alter shipments Lack of trust Smaller carriers Hard to get commitments Not enough trucks in project area Independent evaluation team would have to write multiple expert systems

15 Introducing Plan B!! Lane closures Estimate lane closure impacts Incidents Current travel-time information Historical travel-time information

16 Phase 1 Plan B Status Currently recruiting major carriers Several have shown interest Some from optimization standpoint Some from good corporate citizen standpoint Scoping meetings NDAs

18 What Is a Connected Work Zone? Infrastructure-to-Vehicle messaging DSRC Alert to roadway configuration changes Alert to speed changes

19 Initial Connected Work Zone Plan I35TIDC project has extensive work zone information Map those to SAE J2735 standards Pass information to TxDOT Lonestar TM (Center-to-Center Protocol) Lonestar communicates to RSUs RSUs communicate to connected vehicles CAMP helps TxDOT build / test connectedvehicle and RSZW application

20 Partners CAMP

21 Future Efforts Move from Temple to Austin More complex geometrics More complex travelerinformation needs Mobility35 Project +$4B over 10+ years 86 miles 15,000 lane closures over next 4 years

22 Virtualization Why? Previous few connected vehicles Not enough to get robust data sets Not enough to test applications Prepare for different levels of penetration IOOs need to get ahead of connected-vehicle influx curve Testing Multiple applications in multiple settings Various speeds (slow to freeway) Communication needs
