Controlling an elevator installation using a disadvantage parameter or a disability indicator

An elevator operation method comprising:

• receiving a destination call request for an elevator installation for at least one passenger, the elevator installation comprising at least two elevator cages, the destination call request indicating a desired destination floor;
• as a result of determining that a disadvantage parameter is associated with the at least one passenger, generating call control signals for at least one of the at least two elevator cages to transport the at least one passenger in one of the at least two elevator cages to the desired destination floor;
• and
• as a result of determining that the disadvantage parameter is not associated with the at least one passenger, generating call control signals for at least one of the at least two elevator cages to transport the at least one passenger in one of the at least two elevator cages to a destination floor that is not the desired destination floor.

An elevator installation system, comprising:

• at least two elevator cages;
• a control unit, receiving a destination call request for at least one passenger, the destination call request indicating a desired destination floor, wherein:
• when said control unit determines that a disadvantage parameter is associated with the at least one passenger, said control unit generates control signals for at least one of said at least two elevator cages to transport the at least one passenger in one of said at least two elevator cages to the desired destination floor;
• and
• when said control unit determines that the disadvantage parameter is not associated with the at least one passenger, said call control unit generates call control signals for at least one of said at least two elevator cages to transport the at least one passenger in one of said at least two elevator cages to a destination floor that is not the desired destination floor.
