  2. Presentation Overview • Description of Problem & Solution • Scenarios C O • Data N • Preliminary Results O • ITS Architecture P • Budget & Timeline S • Potential Benefits 8/21/2018 2018 Transportation Technology Tournament 2

  3. Description of Problem & Solution Problem • Over 17% of all traffic fatalities involve pedestrians • Bicyclists constitute 1% of all trips but 2% of all traffic fatalities Solution • Address both safety and mobility issues pertaining to vulnerable road users • Use connected vehicle and autonomous vehicle technology & smart phone applications Feasibility for Adoption • Aligns with the Florida’s existing Pedestrian and Bicyclist Strategic Safety Plan • Generic enough to be adopted by agencies within and outside Florida 8/21/2018 2018 Transportation Technology Tournament 3

  4. Scenario A: Vehicle automatically stops in front of a pedestrian

  5. Scenario B: Vehicles are aware of the presence of bicyclists, and are yielding to bicyclists

  6. Scenario C: Bicyclists are Given the Right-of-way When There Green is are No Vehicles in the Conflicting extended for approaching Approaches bicyclists

  7. Data from City of Gainesville • Ped, Bike, & Vehicle Volume Data from Vantage Live • Vehicle Speed Data from Waze • Signal Timing Plans from the City of Gainesville 8/21/2018 2018 Transportation Technology Tournament 7

  8. Preliminary Results for Scenario A Involving a Distracted Ped. Conflict Analysis Results Case 1 Case 2 (241 Conflicts) (87 Conflicts) 64% Case 1: Conventional Vehicles Case 2: AV with APCAS 8/21/2018 2018 Transportation Technology Tournament 8

  9. Proposed Deployment Location 6 Signalized Intersections along US Hwy 1 in the City of Miami Beach 8/21/2018 2018 Transportation Technology Tournament 9

  10. ITS Architecture: Physical View ITS Personal Proposed: Vehicles Information Centers Roadway Roadway S&PM Device Equipment • CCTV Cameras • RTMC • High contrast • Detection • TMC (Video, LiDAR) and wider, closely spaced • RSUs • Central • Smartphone • OBUs markings signal • Communication with Apps for • APCAS control • Technology (DSRC, Cell) ped/bike systems enabled signs safety 8/21/2018 2018 Transportation Technology Tournament 10

  11. Intersection-level Deployment Costs $12,000/unit Two RSUs per Intersection $8,000/unit Controller Upgrades Cellular Communications $4,000/unit Infrastructure $5,000/unit Collision Avoidance System Total for 6 intersections $246,000 8/21/2018 2018 Transportation Technology Tournament 11

  12. System-level Deployment Costs Smartphone Application $300,000 + $50,000 Sun Guide Interface Upgrade + 10 OBUs for testing $5,000/unit $590,000 + 10 Smartphone OBUs for Ped/Bike $4,000/unit Applications for Testing + $150,000 SE, CEI, Configuration & Integration 8/21/2018 2018 Transportation Technology Tournament 12

  13. Total Cost $246,000 Intersection-level Deployment Cost + $590,000 System-level Deployment Cost + $100,000 Contingency @12% = TOTAL COST $936,000 8/21/2018 2018 Transportation Technology Tournament 13

  14. Timeline • The deployment of 3 Months • Stakeholder Consultation and Needs Assessment the proposed system is anticipated to take 21 months. • ConOps Document, System Engineering Management Plan, RFP Preparation, and Preliminary Engineering 6 Months • The Design-build phase includes FIITT: 4 Months • Procurement Process • Furnish • Install • Integrate 8 Months • Design-Build for Implementation • Test • Train 8/21/2018 2018 Transportation Technology Tournament 14

  15. Potential Benefits Safety • Improved pedestrian/bicyclist detection, verification, validation, and response. • Fewer pedestrian and bicycle crashes at signalized intersections. • Reduce red-light violations. • Help proactively prioritize locations for safety improvements based on conflict analysis. Mobility • Maximizing the available green time and signal phases to accommodate all modes. • Reduced delay and number of stops for bicyclists. • Increasing the throughput of bicycles and vehicles due to advanced detection. • Accommodating higher pedestrian volume particularly in downtown. Enforcement • Future enhancement: An additional detection system that will determine the at-fault road user and issue a ticket. 8/21/2018 2018 Transportation Technology Tournament 15
