Question 7

Only a limited amount of information should be transmitted at high frequency rate in order to limit the use of the bandwidth.

Answer 7

TRUE

Question 8

Beaconing alone can enable simple cooperative applications

Answer 8

TRUE

Answer 9

FALSE

Question 9

It is necessary to have strict regulations about transmission power only to limit energy consumption.

Answer 9

FALSE

Question 10

Heartbeats should contain minimal information since they are periodic signals and many vehicles may be transmitting simultaneously.

Answer 11

TRUE

Question 11

A validation plan is often more comprehensive than a test plan and may include human factor issues.

Answer 11

TRUE

Question 12

Answer 12

TRUE

Question 13

A TRL9 system is probably on the market, a TRL2 system may not even be a prototype.

Answer 13

TRUE

Question 14

If the specificity of a system is 0.5 and the sensitivity is 0.5, we can just as well flip a coin.

Answer 14

TRUE

Question 15

LDW can accept lower specificity than FCW.

Answer 15

TRUE

Question 16

The ecological validity of test-tracks and driving simulators is hard to measure and still to be proven in several contexts.

Answer 16

TRUE

Question 16

One of the main advantages of driving simulations is the possibility to explore safety critical situation with good repeatability.

Answer 16

TRUE

Question 17

Test tracks can expose a vehicle to different environments such as slippery road.

Answer 17

TRUE

Question 18

Whether test-tracks or driving simulators are the best environment for active safety development depends on the specific research questions of the study.
