Over 1/3 of pedestrian fatalities involve alcohol.
According to the National Center for Statistics and Analysis,
13% of drivers
involved in traffic accidents involving fatal injuries
in 2012
had a blood alcohol concentration of .08 g/dL. Of pedestrians involved in fatal crashes with automobiles, 35%—almost twice the amount—
had at least .08 g/dL BAC. This number does not include injuries incurred from non-vehicle-related situations such as crimes involving others or self-endangering circumstances.

Reality of situation
We are interested in a solution that detects stages of drunkenness, and prevents people from walking in traffic, by creating a signal feedback and/or notifying others such as friends or taxi companies via mobile messaging.
Symptoms/Signs:
alcohol breath
alcohol sweat
swaying steps
swayed incline
slurred speech
louder speech
rambling
aggression
glassy/bloodshot and dilated eyes
Dangers:
stumbling, swaying,
bumping into things, dropping things
trying to navigate through streets, falling, tripping
walking into cars, pits, people, dangerous alleys
Alternatives:
calling/notifying friends
calling/hailing a cab
Sensors
The sensors below all relate to ways of detecting the signs of high alcohol-induced impairment. We have included links to the ones that are available as electric sensors.
breath sensor
rhythm detection (of steps)
sweat odor sensor
sound fluctuation detection
eye dilation detector
blood-alcohol level detector
