Problems AddressedProblems Addressed
Traffic chaos caused by presence of emergency vehicles– sirens– increased accidents for emergency
personnel
Traffic chaos caused by large-scale evacuations– resource availability– contraflow
Our ApproachOur Approach
Efficient chaos-reducing information dissemination approach– targeted towards first responders and evacuations– using a vehicular ad-hoc network (VANET)
Provide emergency vehicle path-clearing technique
Provide real-time resource availability information
AssumptionsAssumptions
All vehicles act as information servers relaying information for the VANET.
No location servers or access points on the roadside.
Every vehicle has a navigation system, which plans its route and knows its current location.
Building BlocksBuilding Blocks
Resources: emergency service vehicles (ESVs), gas stations, hospitals, shelters, etc.
Resources (gas stations, shelters, hospitals) periodically broadcast reports– type of resource– availability of resource– location– timestamp of report
Reports updated as availability changes
Information filtered for relevance according to vehicle’s location
ESV Simulation ModelESV Simulation Model
Written in– use of multiple threads for traffic generation,
automobiles and ESVs.
Mobility model– nodes move in piecewise linear fashion, following
