IndyCar - Timings and Scoring
It is very important to understand how each point is scored during the race and how the timings are measured so accurately. We can understand this part of the racing event by the points given below.
For each car a radio transponder with a unique identification number is installed on the driver's left side. This is placed 33 inches away from the tip of the nose cone.
Numerous detection loop antennas are buried in the track surface positioned around the track record that passes time and ID of the radio transponder attached to every car. This information is captured and delivered to the timing and ranking booth through a trackside decoder connected to each antenna.
The information obtained is processed by servers to conclude the results of the session. This recording consists of the results of each session. All the data from the antenna passings, and all the timings of pre-determined sections are set up in the system. The system stores all the timings to the ten-thousandth of a second.
Many other systems are used as backup for the main electronic scoring systems. A high-speed camera, which captures picture for every ten-thousandth of a second, saves all start or finish line passings. After every race, it is used to check the finishing order of all the cars in order to check the close crossings.
Apart from this, manual scoring is done by individual serial scorers who give a written record of all passings at the start or finish line. The scoring computers provide live timing information to every team's pit stand through the Timing and Scoring stand that is positioned in pit lane at the start or finish line. All data captured at every race event are made available through the internet.
