Result of Student’s t-test for comparing the speed in the upstream and downstream while transmitting a message and no message transmission.
| | Subject | Type of t-test | t | value |
| | Vehicle speed in the upstream (the message is transmitted) | Paired-samples t-test | 23.7 | 0 | | Vehicle speed in the downstream (the message is transmitted) | | Vehicle speed in the upstream (no message is transmitted) | Paired-samples t-test | −0.352 | 0.725 | | Vehicle speed in the downstream (no message is transmitted) | | Speed changes while transmitting the message | Independent-samples t-test | −15.8 | 0 | | Speed changes while no message is transmitted |
