How might we create a safer experience for cyclists using an appropriate amount of technology?
SAIVE (smart artificial interactive vehicle ecosystem) is a near-future vision where vehicles and commuters talk to one another while automatically recording and broadcasting data. I worked with Ananda Annisa Prasetyanto and Qiao Yin on this project. Special thanks to Carly Burton at Cognizant.
If SAIVE predicts that a car will make a turn or merge that will impact a nearby person, their turn signal will flash automatically even if the driver hasn't turned on their blinker. Predictions of driver behavior will increase in accuracy over time with more data, although false positives have minimal consequence.
"Dooring" is when an opened car door of a parked car collides with a biker. If SAIVE predicts that a driver passenger opening their door will result in a collision with a cyclist, a notification will be projected onto the car window and the door will be temporarily locked.
Technology behind SAIVE
Halo'd Smart Phones
A "halo'd" object is similar to a smart object, constantly producing data about it's environment. In response to passionate interviews, we intentionally chose to halo the smart phones of cyclists instead of the bikes themselves. Location and velocity data can be captured by a smart phone just in the pocket or backpack of a cyclist.
Drivers already have the potential to produce a large degree of data through normal driving activity. Data can be collected on the speed of the car, angle of the steering wheel, weight on the seat cushion, and many more variables in order to accurately predict driver behavior.
DSRC, "dedicated short range communication", is similar to bluetooth technology and is the backbone of SAIVE. The implementation of DSRC within the ecosystem requires a vast degree of edge computing which isn't possible with today's technology. Edge computing is computing which occurs close to the source of the data itself, instead of being sent to a centralized location then sent back.
Technology Already in Cities
Autonomous vehicles collect vast amounts of data, adding a wealth of information to SAIVE. Furthermore, smart traffic signals, successfully implemented by Stephen Smith at Carnegie Mellon, would contribute data to strengthen the ecosystem.
Our team conducted interviews with commuters (cyclists, motorists, and pedestrians) as well as experts in cycling and traffic flow in order to gain insights on the current transportation system. Mapping a cyclist's experience, ideation with the "crazy-8's" methodology, and gauging potential design solutions were part of the design sprint which led to the formulation of the AI ecosystem SAIVE.
