| |March 20219In Zoomcar, we have used car telematics data from the OBD 2 device to generate a unique driver score. This enables us to reduce ac-cidents and car maintenance costs.Let's understand how Driver Behaviour is analysed:There are 4 main events which help differentiate a bad driver from a good one1. Hard Braking2. Rapid Acceleration3. Over Speeding4. Sharp-TurnsHard Braking utilises the ve-hicle speed and braking data from the OBD device. Sharp dip in speed along with intense braking signifies a hard braking event. The interpreta-tion of event differs with the driving conditions. In bumper to bumper traffic we experience more cases of hard braking as compared to high-way drives. On the contrary, hard braking on highways is fatal due to high speed collisions.Rapid Acceleration can be gauged by a combination of positive change in vehicle speed per sec and intensity on accelerator pedal. This behaviour is mostly noticed on emp-ty roads/ highways or when people get out of idling in heavy traffic.Over Speeding is the most com-mon event amongst drivers espe-cially the young ones. The catch here is, over speeding is relative to traffic condition and speed lim-its. This makes it most difficult to judge. On highways, even 120 km/hr is not over speeding whereas on a traffic laden road 50km/hr is also over speeding.Sharp-Turns are very dangerous and are common events amongst road racers and aggressive style driv-ers. The variables to measure this behaviour are: Azimuth (direction to the north in degrees) and the speed of the vehicle. In naive terms, if change in azimuth per sec is above a certain threshold, at a high speed, it would certainly be counted as a sharp turn. These events are prone to topple the vehicle, thus risking major damage to vehicle and life.Different businesses give differ-ent emphasis to the above events while calculating the driver score. Heavy load transportation compa-nies are very sensitive to over speed-ing and sharp turns as the high mo-mentum of heavy vehicles can cause risk to life around them. Passenger transportation business would give an equal importance to hard brak-ing and acceleration as well because these events are more frequent and decelerate the life of the vehicle.ConclusionVehicle telematics will drive future of Fleet management around the world. In order to be competitive and lower costs, businesses involv-ing large use of vehicles will have to take care of the health of the vehicle and make sure that people are driv-ing them responsibly.
