Enhancing Transportation Safety & Security via Scalable Location-

Based Wireless Applications

Center for Urban Transportation Research (CUTR) Computer Science & Engineering (CSE)


Opportunities

• Proliferation of cell phones & apps – 5.9B mobile subscriptions worldwide, approx. 87% of global

population (Sept. 11)[1]

– 102.4% U.S. mobile subscriber rate (322.9M) (Jun. 11) [2]

– 26.6% of U.S. Households are Wireless–Only (April 11) [3]

– 29B apps downloaded in 2011, up from 9B in 2010 [4]

• Evolution of positioning technologies – U.S. F.C.C. e-911 mandate for locating cell phones ~2001

– 79.9% of cell phones shipped in Q4 2011 (318.3M) had integrated GPS [5]

Positioning Systems

• Global Positioning System (GPS)

– An electronic device that uses satellite signals to determine its current physical location

– Accurate up to 3-5 meters

– Now small enough to manufacture as a “chip” inside another device (i.e. cell phone)

Location-Based Services (LBS)

• Driving directions, “Friend Finder”, or other services that use the knowledge of your current position

• LBS Applications know: – Where you are (Latitude & Longitude) – How fast you are moving – What direction you are traveling

• Only with your permission

• Popular in Europe & Japan, still emerging in U.S.

Wi-Via

• In emergencies, photos taken by the general public can immediately give authorities first-hand view of the situation

• Ex. London Transit Bombings – – Cell Phone photos

– Cell Phone video

• Wi-Via System uses a LBS-enabled application to tell authorities precisely where the photo was sent from.

• Other useful scenarios - Neighborhood Watch, Amber Alerts

Wi-Via

• Wi-Via website – accessible from any laptop or PC with internet access


• Scalable view to local, state, national, and international level


• Satellite view allows visual reference to known landmarks


Wi-Via

• Shows videos and pictures recorded and submitted by mobile phones in real-time


• An “incident” at Tallahassee airport


• Clicking on photo shows full resolution (Current phone allows up to 1280x1024)


• Videos, including sound, are shown in a Quicktime popup


• Can send geographically-targeted multimedia messages to mobile phones


• Can also single out 1 phone and send a private message to only them, or forward their message to someone else

• Clicking on “Call” link immediately calls the phone from your PC using Skype Voice-Over-IP internet “phone”.


• Also allows conference calls with up to 9 mobile phones


Hurricane Evacuation Zone Finder

• User runs phone application, then receives text message back:

– “Evacuation Zone = B. Evacuate when sustained winds = 30+mph, Tide = 13+ft, or when advised. You are currently NOT under a mandatory evacuation.”
