System and method for managing transportation assets
First Claim
1. A method for managing transportation assets, comprising:
- accessing an experience based travel database;
computing a route through a mapped transportation network for a transportation asset based, at least in part, on an analysis data retrieved from the experience based travel database;
receiving a real-time data from one or more of the transportation asset and one or more sensors that monitor one or more route segments in the mapped transportation network; and
updating the route for the transportation asset based, at least in part, on integrating the real-time data with the analysis data.

Abstract
A system for managing transportation assets is provided. The system provides for dynamically (re)computing a trip route based on a real-time updateable stochastic model of a transportation network. The system includes an experience based database for storing a dynamic map data, passive data gatherers that periodically update the experience based database and a processor for (re)computing a trip route based on the experience based database and the stochastic model as influenced by the real-time transportation network data.
It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the application. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

14. A system for reducing variability in a vehicle arrival time, comprising;
-
a historical database that stores a map data, a trip data, a selected route data, a real-time route data, and a real-time vehicle data; and
a receiving system that receives the real-time vehicle data, accesses the historical database, and computes or recomputes a predicted vehicle arrival time and one or more updated vehicle routes that facilitate reducing the variability in vehicle arrival time, based on the real-time vehicle data, the map data, the trip data, the selected route data, and the real-time route data. - View Dependent Claims (15)
