  2. 6,000 Pedestrians were killed in 2016 12% 70,000 Increase in pedestrian fatalities since 2006 Pedestrians were (overall traffic fatalities injured in 2015 have decreased by 18%) 76% 80+ Pedestrian fatalities Age group with highest occurring in urban pedestrian fatalities environments Source: NHTSA 2

  3. Blind Pedestrians Challenges Blind and disabled pedestrians need extra helps at intersections. 1. Difficult to navigate intersection and find crosswalks. 2. Cannot find the pedestrian crossing actuation button. 3. Do not have any information about the status of the signal. 4. Do not know when is safe to start walking. Need a methodology to improve users safety and provide real-time services. 3

  4. eWALK 1. Pedestrian connects to Wi-Fi connected to RSU with special eWalk App that helps with crossing the street. 2. App communicates with RSU that interacts with traffic controller to change light in intersection. 3. RSU broadcasts out Pedestrian Safety message. 4. App uses special algorithm that identifies true location of crosswalk. 4

  5. What the Data Looks Like SmarterRoads Data • Map Data (MAP) (Intersection Geometry information) • Signal Phasing and Timing (SPAT) 5

  6. What We Are Really Looking For.. 6

  7. eWalk App 7

  8. What more eWalk can do Notifications to vehicles are also presented via DSRC PSM (Personal Safety Messages) 1. eWalk communicates via Wi-Fi that pedestrian is in the area 2. Passes information to a DSRC Unit which creates and sends a Personal Safety Message about that Pedestrian. 8

  9. What really matters is.. ACCESSIBILITY + MOBILITY + SAFETY 9
