摘要： A method and device for mitigating passenger-related item loss in a travel-for-hire context are disclosed. An item within a vehicle passenger region is identified, and associated the identified item with a passenger identified by a passenger identifier. A vehicle cabin inventory database is updated with an entry based on the identified item associated with the passenger identifier. A presence of the identified item is detected within the vehicle cabin passenger region when a passenger exit event occurs, and message data is generated including the entry that relates to the identified item based on the presence of the identified item within the vehicle cabin passenger region.

摘要： A vehicle is configured to receive, from a passenger, a pickup request including an approximate location of the passenger, to scan for the passenger after arriving at the approximate location of the passenger, and to determine whether the passenger has been identified by comparing passenger attribute information to results of the scan, and to transmit an approximate location of the vehicle and vehicle identification information to the passenger when the passenger has not been identified or is not accessible for pickup. The passenger is picked up by the vehicle when the passenger has been identified and is accessible for pickup. In addition, the passenger may also use a portable electronic device to identify the vehicle based on the received approximate location of the vehicle and vehicle identification information.
