An automated traffic control system provides real time alternative traffic flow solutions to address traffic congestion on a roadway. A process will pick routes to scan for real-time statistics on the traffic conditions and calculate an average vehicle speed (AVS) for that route, road, highway, etc. If the AVS drops below a historical threshold, a decision matrix is created, whereby all the real-time data is compared with historical data and provides an ideal or best alternative route for “route X”. The operator is provided this information within seconds and is allowed to make a decision to “accept pr decline” the proposed changes in routes. If the proposed changes are accepted, the changes begin to occur automatically such as but not limited to updating electronic signage, changing traffic control signals (all green to keep traffic moving), moving electronic barriers, etc.

Systems and methods for developing business rules for decision engines are provided. A user interface may be provided for inputting business rules and one or more sets of data. The business rules may be in a format of a decision table and/or a decision matrix. The business rules may be applied on the sets of data to generate rule feedback, using an internal decision engine, which denotes coverage of the data by the business rules. The rule feedback may be provided on the user interface, such as with a data coverage indicator utilizing colors, and/or data coverage statistics. The business rules may be defined and validated prior to implementation in an external decision engine. Importable business rules that are adapted to be executed by the external decision engine may be generated based on the business rules. Components of the system may be executed locally on a personal computer.

A virtual device is created from a network of personal wireless devices so that they can query each other regarding the availability and sharing of resources. Each wireless device has a low power, limited range transceiver that enables it to communicate with other wireless devices similarly equipped. Once the network of wireless devices is formed, each wireless device stores a decision matrix that is made up of each wireless device's identification and the available resources within that device. A wireless device can then borrow those resources when an event occurs with that device that requires a resource that cannot be handled by the device.

The method and apparatus to solve this problem in a way which take precise account of printer characteristics is described.

The invention discloses a service-preference-and-network-condition- based vertical handoff method (SNVHO). The handoff method employs a new algorithm for computing weights. Related weights are divided into two kinds: one kind is subjective weights targeting at service preferences and the other kind objective weights determined by network characteristics.

According to the method of the invention, targeting at different service calculation weights, the weights are dynamically changing instead of being fixed values, so that defects of setting the fixed values are overcome. A simulation result show that the service-preference-and-network-condition-based vertical handoff method (SNVHO) is greatly improved in terms performance parameters such as the vertical handoff times, the system throughput, the call drop rate and user costs.
