When a user enters, initializes, or otherwise starts using a navigation function, such as a navigation function on a mobile phone or a stand-alone device, a destination is automatically selected for route generation and production of a navigation output (e.g., an Estimated Time of Arrival (ETA) at the destination). The destination is selected based on current proximity to a location that has a pre-defined destination associated with it. Such pre-defined destination usually is associated with the location by the user. A time of day criteria can also be imposed, such as requiring that the time of day either by in the morning or afternoon, a work day, or a holiday, or the opposite. In one example, locations proximate a work place can be associated with home as a pre-defined destination, and vice versa. A time of day criteria can be imposed, such that even if proximate work and it is in the morning, a route and ETA to home will not be generated.

Aspects provide for a navigation function implemented on a device that has a communication capability (e.g., a mobile phone) in which the navigation function automatically sends an Estimated Time of Arrival (ETA) to a contact associated with a destination selected for navigation purposes. For example, when a user activates a navigation function on his mobile phone, and selects a destination for which a route will be generated from his current location to the destination, a contact phone number associated with that destination will be sent a Short Message System (SMS) message with the calculated ETA. Provisions can be made for automatic updates as the route is traveled. Other information pertaining to the reasons for the ETA can be selected or automatically generated by the navigation function.

A display method and apparatus for a navigation system calculates and displays an estimated time of arrival (ETA) by a standard time at the destination and a POI (Point of Interest) open / close status at arrival, and a time zone change notice when a user crosses a boundary of the time zones. The display method includes the steps of: examining a position of a destination and monitoring a current position of a user during a travel to the destination; retrieving information on time zones and observation of daylight saving time at the current user position and the destination; calculating the ETA at the destination based on a local time and daylight saving time of the destination using the retrieved information; and displaying the ETA at the destination and a current time.

The present invention extends to methods, systems, and computer program products for monitoring signalized traffic flow. A processor in a sensor system or traffic controller interface estimates the time-of-arrival and other traffic flow estimates of one or more vehicles to an intersection stop bar, while the vehicles are within a continuous range of one or more transducers view of the sensor system. A level of efficiency and safety within the signalized traffic flow is estimated by the sensor system based upon one or more of the estimated time-of-arrival and other flow variables estimates and then communicated to the control unit of the traffic signal system. Other flow estimates for each vehicle include but are not limited to: position relative to the stop bar, lane position, velocity, acceleration, time headway and classification.

Methods and systems are provided for selectively using traffic flow data to provide routing options for a vehicle traveling to a destination point.

The customer selects a communications channel for call ahead time and delay notice. Additionally, the system and method may be deployed over a distributed computed system which includes a supplemental computer and a supplemental database. The web based server forwards to the supplemental computer and supplemental database the customer selected communications channel, mode, call ahead and delay data.

A method and system for achieving highly available, fault-tolerant execution of components in a distributed computing system, without requiring the writer of these components to explicitly write code (such as entity beans or database transactions) to make component state persistent. It is achieved by converting the intrinsically non-deterministic behavior of the distributed system to a deterministic behavior, thus enabling state recovery to be achieved by advantageously efficient checkpoint-replay techniques. The method comprises: adapting the execution environment for enabling message communication amongst and between the components; automatically associating a deterministic timestamp in conjunction with a message to be communicated from a sender component to a receiver component during program execution, the timestamp representative of estimated time of arrival of the message at a receiver component. At a component, tracking state of that component during program execution, and periodically checkpointing the state in a local storage device. Upon failure of a component, the component state is restored by recovering a recent stored checkpoint and re-executing the events occurring since the last checkpoint. The system is deterministic by repeating the execution of the receiving component by processing the messages in the same order as their associated timestamp.
