* @desc Check that TLM service stops to broadcast the signal status message in response to a signal request message when the requestor left the intersection
* <pre>
* Pics Selection: PICS_SSEM_GENERATION
* Initial conditions:
* with {
* the IUT being in the "SSEM initial state"
* and the IUT has received SREM
* containing srm.requestor.id
* indicating VID
* and the IUT has already sent SSEM
* }
* Expected behaviour:
* ensure that {
* when {
* the IUT during 2 sec has not received the SREM
* containing stationID
* indicating VID
* }
* then {
* the IUT stops sending the SSEM
* containing srm.requestor.id
* indicating VID
* }
* }
