(Currently, the top speed on most popular cars is less than 300 km/h, i.e., 8,333 cm/s.) - `unknown(0), pedestrian(1), cyclist(2), moped(3), specialVehicles(10), tram(11)` : The speedValue is greater than 3,000. (Currently, non-highway speed limits are usually well below 100 km/h, i.e., 2,778 cm/s.) - `roadSideUnit(15)`: The speedValue is greater than 0. (Road side units shouldn't be transmitting while being transported.) - `Speed-ValueTooLarge-DriveDirectionReverse`: The driveDirection is backward (1) and the speedValue is greater than 3,000. (Usually, backward drives are far less than 50m long, and with maximum possible acceleration of 9 m/s<sup>2</sup> (see trigger conditions for LongAcc-ValueTooLarge), max attainable speed is $`\sqrt{2*9*50}`$ m/s, i.e., 3,000 cm/s.) - `Speed-ChangeTooLarge`: The acceleration calculated from the change in speedValue of two consecutive CAMs meets the trigger conditions of LongAcc-ValueTooLarge. - _SetMbObsEtsiOnlyLongAcc_: - `LongAcc-ValueTooLarge`: The longitudinalAcceleration is greater than 90 dm/s<sup>2</sup>. (Typical $`\mu`$ (coefficient of friction between asphalt and rubber) is 0.9, so maximum possible acceleration is 0.9*9.8 m/s<sup>2</sup>, i.e., 88.2 dm/s<sup>2</sup>.) ```asn1 ```asn1 SetMbObsTgtsCam C-ASR-OBS-BY-TGT ::= { SetMbObsTgtsCam C-ASR-OBS-BY-TGT ::= { {MbSingleObservation{{SetMbObsCamBeacon}} BY {MbSingleObservation{{SetMbObsCamBeacon}} BY Loading @@ -208,7 +237,7 @@ SetMbObsTgtsCam C-ASR-OBS-BY-TGT ::= { ``` ``` ### <a name="SetMbEvCam"></a>SetMbEvCam ### <a name="SetMbEvCam"></a>SetMbEvCam This data type defines the IOS for CAM Evidence.
