  4. 4. Our Approach <ul><li>Build upon NOTICE </li></ul><ul><ul><li>Architecture for the No tification of T raffic I ncidents and C ong e stion </li></ul></ul><ul><li>Add temporary infrastructure to facilitate long-range communication </li></ul><ul><ul><li>from emergency management centers to drivers </li></ul></ul><ul><ul><li>backward information propagation during contraflow </li></ul></ul>
  5. 5. NOTICE Overview <ul><li>Embed intelligent sensor belts in the highway </li></ul><ul><ul><li>allow the roadway to associate messages with physical vehicles </li></ul></ul><ul><li>When a car passes over the belt, it reports its speed to the belt </li></ul><ul><li>The belt makes decisions about where congestion is occurring based on reports from cars and other belts </li></ul>speed 55
  6. 6.

  7. 7. NOTICE Belt-to-Belt Communication <ul><li>Individual belt in each lane </li></ul><ul><li>Connected belts ( sub-belts ) communicate instantaneously </li></ul><ul><li>Non-connected belts do not directly communicate </li></ul><ul><ul><li>use cars as data mules </li></ul></ul><ul><li>Gives encrypted message to a car to drop off at next belt </li></ul>[avg spd 55] [avg spd 55]

NOTICE Information Propagation <ul><li>B 1 is aware of traffic slowdown </li></ul><ul><ul><li>creates encrypted message with latest traffic statistics </li></ul></ul><ul><li>Information is provided to B 2 </li></ul><ul><li>B 2 uploads message onto car destined for C 2 </li></ul><ul><li>When C 2 receives message, it provides it to C 1 </li></ul><ul><li>C 1 notifies passing cars </li></ul>A 1 B 1 C 1 A 2 B 2 C 2 EXIT 12
