System and methods for determining and disseminating current traffic information and / or route information are presented. For example, in accordance with one embodiment of the present invention, traffic condition information is collected from mobile units that provide their location or position information. The traffic condition may be determined, for example, based on the difference between the velocity of each mobile unit and the speed limit corresponding to their location. Furthermore, the fastest routes between two locations may be determined and provided based on historical and / or current conditions and provided to a mobile unit. In accordance with another embodiment of the present invention, route information may be utilized to determine whether a mobile unit (e.g., associated with a vehicle) is allowed or prohibited from traveling along a certain route.

A system for automated inventory management and material handling removes the requirement to operate fully automatically or all-manual using conventional vertical storage and retrieval (S&R) machines. Inventory requests to place palletized material into storage at a specified lot location or retrieve palletized material from a specified lot are resolved into missions for autonomous fork trucks, equivalent mobile platforms, or manual fork truck drivers (and their equipment) that are autonomously or manually executed to effect the request. Automated trucks plan their own movements to execute the mission over the warehouse aisles or roadways sharing this space with manually driven trucks. Automated units drive to planned speed limits, manage their loads (stability control), stop, go, and merge at intersections according human driving rules, use on-board sensors to identify static and dynamic obstacles, and human traffic, and either avoid them or stop until potential collision risk is removed.

System and method for identifying speeding violations, comprising determining a current speed and a current location of a vehicle, determining a posted speed limit for the current location from a speed-by-street database, comparing the current speed of the vehicle to the posted speed limit, and evaluating whether the current speed exceeds the posted speed limit. Errors are identified in the speed-by-street database by storing a plurality of speeding violation records, wherein the speeding violation records each include a speeding event location; analyzing the speeding violation records to identify one or more speeding event locations having multiple speeding violations; comparing a posted speed limit at the one or more speeding event locations having multiple speeding violations to corresponding speed limit data in the speed-by-street database; and identifying one or more speed limit entries in the speed-by-street database that do not match the posted speed limit.

The alert includes one or more caution attributes when the current speed range of the vehicle is within the caution range. The alert includes one or more warning attributes when the current speed range of the vehicle is within the warning range. The alert includes one or more at speed attributes when the current speed range of the vehicle is not within the caution range or the warning range.

The present invention combines the geographical coverage possible with fixed, pre-defined route segment costs (e.g. the legal speed limit) with, wherever possible, richer time dependent costs. A user of, for example, a portable navigation device, can therefore continue route planning as before to virtually any destination in a country covered by the stored map database, but wherever possible, can also use traffic data with time-dependent costs, so that the effect of congestion with any time predictability can be accurately taken into account as an automatic, background process. It leaves the user to simply carry on driving, following the guidance offered by the navigation device, without needing to be concerned about congestion that exists now, and whether it will impact his journey.

A vehicle warning system is responsive to vehicle speed and position as determined by GPS or other location based system information to alert a vehicle operator of potentially unsafe conditions when either exceeding the speed limit on a given road segment or when approaching coordinates of a designated location alert point.

A telemetry system coupled to a vehicle can communicate with a remote site using the overhead control channels of a wireless network, such as a cellular mobile radiotelephone network. The telemetry system can monitor or control aspects of the vehicle's operations based on remote user input. The telemetry system can take steps to reduce its consumption of electricity. When conditions warrant, the telemetry system can disable a driver's attempt to start the vehicle. A relay can consume minimal electricity until an unauthorized driver attempts to start the vehicle, at which time the telemetry system can energize the relay to interrupt the starting sequence. The telemetry system can monitor a driver's driving practices and report incidences that meet preset criteria, such as violating a speed limit for a selected amount of time or a crossing of a geographical boundary.

Autonomous and manually operated vehicles are integrated into a cohesive, interactive environment, with communications to each other and to their surroundings, to improve traffic flow while reducing accidents and other incidents. All vehicles send / receive messages to / from each other, and from infrastructure devices, enabling the vehicles to determine their status, traffic conditions and infrastructure. The vehicles store and operate in accordance with a common set of rules based upon the messages received and other inputs from sensors, databases, and so forth, to avoid obstacles and collisions based upon current and, in some cases, future or predicted behavior. Shared vehicle control interfaces enable the AVs to conform to driving activities that are legal, safe, and allowable on roadways. Such activities enable each AV to drive within safety margins, speed limits, on allowed or legal driving lanes and through allowed turns, intersections, mergers, lane changes, stops / starts, and so forth.
