Definitions

• the invention relates to a remote query system for providing Information about traffic conditions, especially traffic jams, denser Traffic, fog, slippery, ghost drivers, on expressways.
• a disadvantage of the known traffic jam systems is that they are not can react flexibly to the current traffic situation, as the time of the day Origin until a traffic jam is reported and until the Traffic jam reports are often very long.
• Telephonic remote access systems are known which are used, for example, for Querying account balances or making bookings at Telephone banking or order by telephone in mail order.
• the user is made of predeterminable with an announcement text Announcement text blocks are instructed for use or the Desired information transmitted, the user his commands outputs coded using the keypad of his phone using the multi-frequency method.
• remote telephone inquiry systems are known, their operation and control via pure voice signals, which a Able to evaluate the speech recognition unit of the remote access system is.
• the invention has for its object to provide a traffic jam system To make available which information about the Is able to provide traffic conditions and this to any Makes times available for those interested.
• the task is solved by a remote inquiry system for the provision of Information about traffic conditions on expressways with a Input element, which user information is able to recognize, and an output element, which predeterminable text modules compile and the user as perceivable by this Is able to transmit signal.
• the input element takes the User information received via a reporting channel, information about Location and type of traffic disruption, together with information be stored in a database about the time of the call. Farther it takes from the user information that is received via a query channel, Information about the route of interest, what the Remote query system a database query for the route in question carries out, and the determined information about the Traffic conditions communicated to the user through the output element will.
• the remote query system according to the invention works mainly on a telephone basis, with callers using the reporting channel the database provide with information and this again via a query channel can retrieve. In addition, there is also an online query option provided on the Internet.

• traffic information Currently many drivers have a mobile phone with which they can easily Remote query system can report malfunctions. Such a call goes thereby via a reporting channel with the remote access system.
• Corresponding can provide information about the traffic situation via a query channel can be called up by telephone. Message and query channel can either by two different phone numbers or by an input query be distinguished. Furthermore, access to the query channel is via the internet provided.
• the caller When a call arrives via the reporting channel, the caller is first asked to indicate the street name, direction of travel, location and type of traffic disruption, preferably by specifying the relevant junctions or motorway junctions.
• the speech recognition unit converts this information into computer-usable information about the disrupted route.
• the computer determines on the basis of the direction of travel and the name of the motorway or on the basis of the respective connection points or intersection points in which route segment the fault is located.
• the corresponding route segment is then named in the database Traffic jam "or the respective fault.
• the time of the call is also saved.
• the remote query system preferably plays that of the Speech recognition unit recognized and converted information, composed of saved text modules, the caller with the help the starting element again and takes it only after it Confirmation in the database. This confirmation that the speech signals recognized correctly, for example by pressing a button multi-frequency coded or also by voice input.
• An over Incoming calls to the reporting channel are preferably free of charge.
• the user can inquire about the road conditions on certain routes with a call coming in via the query channel or via the Internet.
• the remote query system uses the output element to request street names and directions and, if applicable, the planned route section.
• the speech recognition unit determines the keywords from the user's speech signal and converts them into information that can be used by the computer. With this information, the assignment to a route section stored in the database is made, which can consist of one or more route segments. These route segments are each with the characteristic Disorder "or no disturbance ".
• the remote query system preferably offers that User to determine an undisturbed evasion route and notify him these on request.
• the message transmitted to the caller is composed of several announcement text modules, for example a basic module such as On the ... between ... and ... is reported.

If there is no disturbance on the queried route, this is communicated in a standard message. If the planned route could not be identified by the speech recognition unit, the caller is preferably requested to enter it again.
