摘要:
The present invention is a method and an apparatus for predicting future travel times over a transportation network. In one embodiment, a method for predicting future travel times over a transportation network includes receiving a data point indicating a real-time volume of traffic on the link at a given time and updating a template representative of an observed traffic pattern on the link in accordance with the received data point. A future travel time over the link can then be estimated in accordance with the updated template. Thus, the template is able to adapt to dynamically changing traffic patterns, taking these changing traffic patterns into account when making predictions of future traffic patterns.

The present invention is a method and an apparatus for estimating real-time travel times or traffic loads (e.g., traffic flows or densities) over a transportation network based on limited real-time data. In one embodiment, a method for estimating a travel time over a transportation network comprising at least a first link and a second link includes receiving a data feed associated with a real-time traffic flow over the first link, estimating a first travel time over the first link based at least in part on the data feed, and estimating a second travel time over the second link, also based at least in part on the data feed. The method assumes that a real-time data feed is not available for the second link, and thus estimates the traffic flow over the second link based on the known traffic flow over the first link and other known data, such as historical traffic patterns and physical parameters of the transportation network.

Yield management techniques are provided. In one aspect of the invention, a technique for managing one or more computing resources comprises the following steps/operations. Data associated with at least one potential demand for use of the one or more computing resources is obtained. Then, a management model (e.g., a yield management model or a revenue management model) is generated in accordance with at least a portion of the obtained data, wherein the management model is operative to determine an allocation of the one or more computing resources based on combinations of price levels and service levels that may be offered to one or more users of the one or more computing resources so as to attempt to satisfy at least one management goal.
