Communication between driver and passenger is now unthinkable without a smartphone. Mobile services make it possible to plan times and routes, choose the right vehicle or fare, and make the payment process much easier. And advanced technology protects passengers and drivers on the road. How exactly and how effective is this protection? We tell you about the tools already in use in the Yandex. Go service.
The most important tool for preventing dangerous situations on the road is speeding. And here, in addition to traffic rules and traffic cameras, there are smart algorithms looking after taxi drivers (and carshare customers). They are trained both to inform the speeding driver about the speeding and to impose personal electronic “sanctions” against him.
For example, if a taxi driver often exceeds the speed limit by at least 20 kilometres per hour, he receives a warning. After a series of such reminders, the algorithm can decide to terminate access to the service.
Driving style analysis
The algorithms not only record speeding but also… driving style analysis. How does it work?
The system uses data from the accelerometer and gyroscope in the driver’s mobile device to detect excessive braking, accelerating, turning and changing lanes. Of course, such manoeuvres are often forced, e.g. in emergency situations. If the driver had to brake too hard, the service may consider this to be a likely accident, contact the user and clarify what happened. But if nervous or dangerous driving becomes a habit, the system will first try to reason with the driver by asking him to be more careful, and if the advice is ignored, it will cut off the daredevil’s access to bookings.
In addition to collecting data from mobile devices, all drivers are physically tested before they go on the road. But another promising testing procedure also involves technology – and it is already being applied by Yandex.
A new development is an in-car camera, which uses special software to conduct a comprehensive attention and concentration test.
Experimental technology scans the driver’s face, capturing a number of parameters that can tell if the driver is tired or not paying attention to the road. If the system detects that a person is distracted, blinks suspiciously often or has difficulty concentrating, it issues warning signals. An excessive number of such warnings can lead to restricted access to Yandex Go service orders and a forced pause to restore the work/rest balance.
Ratings and scores
Not only drivers but also taxi passengers are now being rated – and this too is a very effective tool. However, unlike those sitting in the back seat, the people behind the wheel are responsible for the safety of the ride.
Users of Yandex services, for example, are familiar with the five-point scale by which you can rate a driver when you create an order. However, not everyone is aware that lowering a driver’s personal rating to 4.5 – that is, to a pretty good value by conventional standards – can lead to the suspension of work in a taxi and the ability to fulfil orders. Since not only dangerous behaviour on the road, but also unpleasant odour in the cabin or driving without a medical mask for example, “questionable” drivers are put on “test journeys” during which they get their score corrected. These test journeys differ from normal journeys only in the increased attention given by the service.
