A route is selected on the basis of received information.

Description

Intelligent traffic reporting system

Extensive disclosed telecommunications and intelligent common signal channel field, particularly the electronic communication reporting system field of the present invention relates to.

For example can frequent variations along any traffic congestion of giving fixed line or these driving situations of accident, particularly in the city, when the driver drive by its different when regional especially like this.In addition, maximum traffic delay occurs in travelling when on and off duty.Such delay is generally all by traffic hazard, road structure, and speed of a motor vehicle monitoring station, or driver overcurious causes.Many drivers rely on radio broadcasting, yet have too many situation, wherein, just hear broadcasting after the selected rough sledding of this driver is with the road that takes place, and make the road that arrives the destination crowded thus.Also possible is traffic conditions rather than a kind of selection that traffic returns provides road.Therefore, need a kind of fast easily method and system be used to receive given city, the traffic returns of road and direction is to avoid the traffic delay of every day.

A kind of traffic returns system comprises that at least one is linked to the server of a plurality of sensors, is used for detecting the traffic conditions at least one area.This server comprises: a receiver is used to receive traffic conditions information; A receiver is used to receive the signal of asking traffic returns; A storage arrangement is connected to receiver, is used to store this traffic conditions information; And a transmitter, be used to send traffic returns.

Fig. 1 explanation is by a kind of intelligent traffic reporting system of the present invention.

Fig. 2 represents a kind of environment, wherein can advantageously use by a kind of system of the present invention.

With reference to Fig. 1, expression is by a kind of intelligent traffic reporting system 10 of one aspect of the invention, and this traffic returns system comprises at least one server 12, is linked to a plurality of sensors 14, be used to detect the traffic conditions at least one provincialism zone, and at least one subscriber unit 16.This subscriber unit 16 preferably can with the vehicles for example the cellular telephone or any other the frequency taken that carry of truck penetrate communicator.Server comprises a receiver 18, is used for the traffic conditions information that receiving sensor 14 produces.

Receiver 18 can be connected to a telephone line, and this telephone line is connected to a communication network 20 successively, for example public telephone network or other suitable networks.Receiver 22 can be suitable for receiving the signal that comprises the voice request that is used for traffic returns, perhaps is suitable for receiving non-voice (for example text or the data) signal that comprises the request that is used for (comprising but non-being confined to) traffic returns in addition.In other words, receiver 22 can comprise the voice recognition capability that is used to explain the voice request that is received, and perhaps this server can comprise an independently composition with voice recognition capability.Also may comprise speech recognition in subscriber unit, this subscriber unit can transmit specifies the data-signal that is used for this server 12.

System 10 also comprises a receiver 22, is used to receive the signal of the traffic letter information that is included in sensor 14 receptions.This receiver 22 comprises the circuit that is used to handle and store the transport information that is received.Server 12 also comprises an accumulator apparatus 24, is connected to receiver 22, is used to store traffic conditions information.This accumulator apparatus 24 comprises the database of this transport information.It is upgraded continually, so that make data useful.This accumulator apparatus can be a hard disk drive, has enough capacity, stores the data of the traffic conditions in a plurality of geographic areas or the road.Server also comprises a cpu system 26 and is usually included in known subsystem (for example the I/0 subsystem 27) in the server in addition.The component that has omitted other for simplicity is connected with it.Server 12 comprises a transmitter 28, is used to send traffic returns.This transmitter 28 can be suitable for launching the data-signal that comprises requested traffic returns, and perhaps it can be suitable for launching the voice signal of being convenient to by the cell phone reception that forms request.In this server, might comprise a text-voice conversion device, so that the such signal that is suitable for by the cell phone reception to be provided.

Traffic sensor 14 may be embodied to a plurality of gamma cameras that are configured in diverse location, can determine traffic conditions from their theres.Proximity sense can use the fuzzy logic circuit in addition, to obtain and to transmit the data of the traffic conditions that is illustrated in any given road or position.Sensor can for example wire circuit or the so any suitable device of radio-frequency unit be connected to communication network by some.At sensor is under the situation of gamma camera, and image can arrive the transport information processing enter by the circuit of regulation, and staff or suitable equipment can produce transport information in the database that is stored in server 12 with picture there.

Server 12 can comprise the hardware that is suitable for according to above explanation work, and perhaps a common server can be programmed, so that carry out work according to the common hardware that comprises a digital signal processor.

With reference to Fig. 2, point out the performance of a kind of environment, wherein using system 10 advantageously.Client unit 16 is one and moves (honeycomb) phone that it is connected to the network 20 that is connected to server 12 by PSTN by radio frequency.In this environment, from the original position (family) there are some alternative paths in (office) to the destination.The driver makes a phone call to ask to determine the traffic returns of starting point and destination.This request is preferably undertaken by calling out a number with appointment of interactivity responding ability.This system receives voice request, and it is transformed into can be by the data-signal of server 12 processing, and retrieval is used for database for information about, it is transformed into telephone voice signal, and it is transmitted into driver's telephone set 16.The driver is according to the Information Selection path that receives.In the case, the driver leaves drive southwards 30 miles office (Fort Lauderdale) of its family (Florida, US (state) boynton beach).Suppose that the volume of traffic that travels southwards is bigger than the volume of traffic in the standby path of US1 and national highway 628 on the 1-95 road.This selection can be saved a large amount of time of driver.

Therefore, when what having described at this being the most preferred embodiment of considering at present, those professional and technical personnel should be understood that in spiritual scope of the present invention can carry out other modification.
