PORTABLE PROCESSING DEVICES
First Claim
1. A portable processing device comprising means for receiving positioning data indicative of a position of the processing device, an output device, a processor and memory having stored thereon map data, wherein the processor is arranged to determine a position on the map data based on the positioning data, determine a speed to travel to arrive at a traffic control signal, which switches between two or more conditions to indicate a right of way, when the traffic control signal has a particular condition and cause the output device to output at least one of an audio and visual instruction to indicate the determined speed to travel.

Abstract
This invention concerns a portable processing device 200, such as a navigation device, comprising a positioning device 250,251 for determining a position of the processing device 200, an audio and/or visual output device 240/261, a processor 210 and memory 230 having stored thereon map data. The processor is arranged to determine a position on the map data based on an output from the positioning device 250/251, determine a speed to travel to arrive at a traffic control signal, which switches between two or more conditions to indicate a right of way, when the traffic control signal has a particular condition and cause the audio and/or visual output 240/261 to output an instruction to indicate the determined speed to travel. The invention also concerns a server 302 for interacting with the portable processing device 200.

11. A server comprising a processor, a data link for communicating with portable processing devices and a data link for receiving information indicative of the condition of traffic control signals, the processor arranged to process the information to determine the condition of the traffic control signals and communicate the condition of the traffic control signals to at least one of a remote processing device and one or more of the portable processing devices.

12. A server comprising memory having stored thereon map data and data concerning the cyclic condition of traffic control signals, which switch between two or more conditions to indicate a right of way, a processor and a data link for communicating with portable processing devices, the processor arranged to, in response to receiving a position fix from a portable processing device, determine a speed to travel to arrive at at least one of the traffic control signals along the route when the at least one traffic control signal has a particular condition and communicate the speed to travel to the portable processing device.

14. A method of providing driving suggestions comprising:
-
determining a position on map data based on an output from a positioning device, identifying a traffic control signal, which switches between two or more conditions to indicate a right of way, on a route, determining a speed to travel to arrive at the traffic control signal when the traffic control signal has a particular condition, and causing at least one of an audio and visual output of an instruction to a user of a vehicle indicating the determined speed to travel.
