This effort undertakes the creation of an Airport Ground Resource Planning (AGRP) tool. Little or no automation is currently available to support airport ground resource allocation decisions. The AGRP tool provides visualization both of the resource assignments as well as other information relevant to making resource assignment decision. In addition, AGRP automates or advises resource assignments, improving efficiency while reducing workload. In Phase 2, we propose to continue development of the AGRP tool through four work areas. First, we will complete the map and Resource Allocation displays. We will also complete the algorithm to automate resource allocation decisions and integrate it with the displays. The resulting AGRP prototype will be evaluated operationally. We will also extend the Phase 1 work to develop a block out time predictor, which would have tremendous application and benefit in other traffic management systems. In Phase 1, we proposed an architecture in which applications such as AGRP can subscribe to receive SMS data via a standardized interface. In Phase 2 we will complete the specifications for and implementation of this interface, which will replace the existing SMS client-server communication.
