Abstract: A system for a vehicle includes a traction battery, an engine, and a controller configured to inhibit requests to start the engine in response to both the vehicle being within a first radius about a previously-identified frequent destination and an available battery energy being greater than twice a total battery energy expended during a prior trip to the destination from a second radius about the destination, the second radius being smaller than the first radius.

Abstract: Methods and apparatus for presenting time-based and location-based traffic condition information to motorists. Traffic condition information is collected to create historical time-based and location-based traffic data, which is displayed, in one embodiment, on a congestion clock. The traffic condition data includes, in various embodiments, speed data, volume data, occupancy data, and travel time for a specific section of roadway.

Abstract: Methods and apparatus for a telephone based traveler information dissemination system that traffic and roadway condition information upon demand. A traveler communicates with a server over a telephone. The server receives a first and second geographic location and generates travel data, which is delivered to the traveler via facsimile or e-mail.

Abstract: Methods for a determining a normalized lane occupancy and for monitoring signal quality for a vehicle detection system. Such methods include, in one embodiment, measuring a speed of a vehicle with an inductive vehicle detector, measuring an on-time for the vehicle crossing a wire loop sensor of the inductive vehicle detector, determining an inductive length of the vehicle from the measured speed, and computing a normalized on-time by subtracting a longitudinal length of the wire loop sensor from the inductive length and dividing the difference by the measured speed.
