Definitions
- Information regarding vehicular travel is currently gathered using a variety of techniques. For example, information relating to vehicular accidents is gathered through eyewitness reports to police or emergency personnel at the scene, or from motorist telephone reports received from emergency phones or cellular phones. Traffic is also observed visually from helicopters, which may utilize video cameras to record such traffic and facilitate the reporting of various travel characteristics. Video cameras are also placed adjacent to certain roadways to allow remote observation of travel conditions in front of the camera. In addition, sensors may be placed on certain roadways in order to count vehicles. Motorists obtain the gathered travel information through a variety of means, including television reports, radio reports, and internet websites.
- Another problem with current methods is that it is difficult for motorists to get travel information for a specific area whenever they want such information.
- Television and radio broadcasts of travel information provide the same report to all listeners and viewers, and thus generally cover only the most commonly used roadways and the most serious travel problems. This forces the motorist to listen or watch a report, which usually contains far more information than he or she desires, and sometimes does not even contain the desired information at all. Additionally, the information is broadcast on the relevant station's schedule, and not necessarily when the motorist needs the information.
- One effect is that information can be stale by the time it is reported to the motorist, either because the travel condition has cleared or because the motorist has passed the point at which he could have selected a different route to his destination.
- Some internet websites offer a more specific report providing only information for the areas of interest to the user, but these typically are not accessible to motorists while they are operating their vehicles.
- Vehicles today may contain equipment that utilize vehicle location information to support theft recovery or operator assistance, e.g., “LoJack” and “OnStar” equipment.
- the equipment communicates wirelessly with remote central systems to provide such support.
- the roadway information system may comprise, for example, a first mobile client system associated with the first roadway vehicle, a second mobile client system associated with the second roadway vehicle, a wireless communication network, and a processing system communicatively coupled to the wireless communication network.
- the first mobile client system may deliver first travel related data to the processing system via the wireless communication network.
- the processing system may deliver second travel related data to the second mobile client system via the wireless communication network, where the second travel related data relates at least in part to the first travel related data.
- the roadway information system may comprise, for example, a wireless communication network, a plurality of mobile client systems communicatively coupled to the wireless communication network, and a processing system communicatively coupled to the wireless communication network.
- Each of the plurality of mobile client systems may deliver travel related information via the wireless communication network.
- the processing system generates and communicates data based on the travel related information delivered by each of the plurality of mobile client systems.
- a method in accordance with the present invention may comprise, for example, one or more of the following: delivering a first travel related data by a first mobile client system to a processing system via a wireless communication network, the first mobile client system associated with a first roadway vehicle; generating a second travel related data by the processing system, the second travel related data related at least in part to the first travel related data; and delivering the second travel related data by the processing system to a second mobile client system via the wireless communication network, the second mobile client system associated with a second roadway vehicle.

- Information regarding vehicular travel is currently gathered using a variety of techniques. For example, information relating to vehicular accidents is gathered through eyewitness reports to police or emergency personnel at the scene, or from motorist telephone reports received from emergency phones or cellular phones. Traffic is also observed visually from helicopters, which may utilize video cameras to record such traffic and facilitate the reporting of various travel characteristics. Video cameras are also placed adjacent to certain roadways to allow remote observation of travel conditions in front of the camera. In addition, sensors may be placed on certain roadways in order to count vehicles. Motorists obtain the gathered travel information through a variety of means, including television reports, radio reports, and internet websites.
- Motorist reports of travel data are manually made on an ad hoc basis, and thus there often is no information regarding travel conditions in an area of interest. Similarly, helicopters, video cameras and sensors currently are only deployed in certain areas. Since the cost of such monitoring devices is very high, and since they require trained personnel to operate them, there are significant cost barriers that prevent such monitoring devices from being used to cover a significant percentage of roadways simultaneously. Additionally, because information gathering from motorist report, video cameras, and helicopters is performed manually, there can be significant latency when delivering the travel information.
- Another problem with current methods is that it is difficult for motorists to get travel information for a specific area whenever they want such information. Television and radio broadcasts of travel information provide the same report to all listeners and viewers, and thus generally cover only the most commonly used roadways and the most serious travel problems. This forces the motorist to listen or watch a report, which usually contains far more information than he or she desires, and sometimes does not even contain the desired information at all. Additionally, the information is broadcast on the relevant station's schedule, and not necessarily when the motorist needs the information. One effect is that information can be stale by the time it is reported to the motorist, either because the travel condition has cleared or because the motorist has passed the point at which he could have selected a different route to his destination. Some internet websites offer a more specific report providing only information for the areas of interest to the user, but these typically are not accessible to motorists while they are operating their vehicles.
- Vehicles today may contain equipment that utilize vehicle location information to support theft recovery or operator assistance, e.g., “LoJack” and “OnStar” equipment. The equipment communicates wirelessly with remote central systems to provide such support.
- Further limitations and disadvantages of conventional and traditional approaches will become apparent to one of ordinary skill in the art through comparison of such systems with the present invention as set forth in the remainder of the present application with reference to the drawings.
- Aspects of the present invention may be found in, for example, systems and methods for exchange of travel data in a roadway information system associated with a first roadway vehicle and a second roadway vehicle. In one embodiment, the roadway information system may comprise, for example, a first mobile client system associated with the first roadway vehicle, a second mobile client system associated with the second roadway vehicle, a wireless communication network, and a processing system communicatively coupled to the wireless communication network. The first mobile client system may deliver first travel related data to the processing system via the wireless communication network. The processing system may deliver second travel related data to the second mobile client system via the wireless communication network, where the second travel related data relates at least in part to the first travel related data.
- In another embodiment, the roadway information system may comprise, for example, a wireless communication network, a plurality of mobile client systems communicatively coupled to the wireless communication network, and a processing system communicatively coupled to the wireless communication network. Each of the plurality of mobile client systems may deliver travel related information via the wireless communication network. In addition, the processing system generates and communicates data based on the travel related information delivered by each of the plurality of mobile client systems.
- In yet another embodiment, a method in accordance with the present invention may comprise, for example, one or more of the following: delivering a first travel related data by a first mobile client system to a processing system via a wireless communication network, the first mobile client system associated with a first roadway vehicle; generating a second travel related data by the processing system, the second travel related data related at least in part to the first travel related data; and delivering the second travel related data by the processing system to a second mobile client system via the wireless communication network, the second mobile client system associated with a second roadway vehicle.

FIG. 1 is a diagram illustrating a roadway traveldata exchange network 100 supporting collection, processing and exchange of travel data, in accordance with various aspects of the present invention. The roadway traveldata exchange network 100 comprises acommunication infrastructure 115, pluralities ofclient systems collection systems 105, and a storage andprocessing system 117. The plurality ofclient systems 103 comprisecollection systems 111 and retrieval/post-processing systems 113. However, the plurality ofclient systems 119 comprise retrieval/post-processing systems 113 and nocollection systems 111. - The plurality of
client systems 103 collect travel data and deliver the collected data to the storage andprocessing system 117 via thecommunication infrastructure 115. The storage andprocessing system 117 also receives collected travel data from the supportingcollection systems 105. These collection processes occur both periodically and in real time. - To support the pluralities of
client systems processing system 117 correlates, combines and otherwise processes the collected travel data to generate processed data and instructions. The processed data and instructions are delivered to the pluralities ofclient systems communication infrastructure 115 for post-processing. Post-processing by the pluralities ofclient systems - Some of the pluralities of
client systems client systems client systems client systems 103, installed or associated with roadway vehicles: (1) collect travel data via thecollection systems 111; (2) exchange collected travel data with the storage andprocessing system 117, theclient systems 119, others of theclient systems 103, and the supportingcollection systems 105; and (3) post-process travel data retrieved from the storage andprocessing system 117, theclient systems 119, others of theclient systems 103, and the supportingcollection systems 105. Although the plurality ofclient systems 119 do not perform collection, they also post-process such retrieved and received travel data via the communication infrastructure from thesystems other client systems 119. - The pluralities of
client systems - Collection of travel data by the plurality of
client systems 103 is accomplished in several ways. Some of the plurality ofclient systems 103 receive instructions from thesystems client systems 103 to deliver, or collect and deliver, certain travel data. Any of the plurality ofclient systems 103 may be pre-configured or instructed to regularly collect and deliver such travel data without awaiting specific requests. Such “pre-arranged” collection and delivery can occur continuously or as travel data becomes available. The collection and delivery process performed by each of the plurality ofclient systems 103 may be activated or deactivated via the communication infrastructure or through direct interaction with theclient systems 103. The retrieval and post-processing of the plurality ofclient systems 103 may be similarly activated or deactivated. - Another way for collecting information is for the plurality of
client systems 103 to automatically initiate collection (and subsequent delivery) of travel data. For example, upon sensing motion, periodic collection and delivery might be automatically initiated by theclient systems 103.Such client system 103 might also periodically collect and deliver the moving vehicle's geographic location, its speed, direction and other travel data. Alternatively, the plurality ofclient systems 103 may be triggered manually to initiate collection and/or delivery of travel data. - After processing travel data delivered by one of the plurality of
client systems 103, the storage andprocessing system 117 may return processed travel data and/or instructions to the delivering one of the plurality ofclient systems 103. In addition, the storage andprocessing system 117 delivers the processed travel data and related instructions to others of the pluralities ofclient systems client systems 103 in response to travel data collected from another of the client systems. Any of the pluralities ofclient systems client systems - The roadway travel
data exchange network 100 is enhanced with capability of receiving additional information that may relate to travel. Such additional travel-related information may be collected by supportingcollection systems 105. For example, various governmental agencies or news organizations will have the capability to contribute travel-related data. Governmental agencies that may contribute travel-related data to the roadway travel data exchange network include, for example, a local city police department, a state police department, a sheriff's department, a highway patrol, and a meteorological agency. The travel-related data may be collected by using aclient system 103, in a similar manner as discussed above. The travel-related data may comprise, for example, information about the number of vehicles that pass through a certain part of a road, vehicle speed, and direction of travel. If the travel-related data is collected by the governmental agency representative using a device similar to aclient system 103, the device may automatically collect and transmit the travel-related data to the storage andprocessing system 117 for further processing. The governmental agency representative may also collect travel-related data by observation and then enter it into the roadway travel data exchange network by transmitting it directly to the storage andprocessing system 117. For example, a police officer may be monitoring a busy road intersection and may observe a traffic accident. As a result of the accident, all lanes of the road may become blocked and traffic flow may quickly deteriorate. The police officer may then transmit to the storage andprocessing system 117 his exact location and the fact that the specific road has been blocked in both directions due to a traffic accident. - The supporting
collection systems 105 may comprise, for example, weather-related data collection systems. The weather-related data may be automatically collected by weather sensors placed at key intersections, highways, or roads. The weather-related data may include, for example, outside temperature, precipitation amount and emergency weather data (such as information for an approaching tornado). Certain weather-related data may be entered into the roadway travel data exchange network and transmitted to the storage andprocessing system 117 via aclient system 103. The supportingcollection systems 105 may also comprise a meteorological data collection system that delivers travel data in the form of weather information to the storage andprocessing system 117. - The supporting
collection systems 105 also deliver travel data directly to theclient systems communication infrastructure 115. Instructions may also be delivered by the supportingcollection systems 105 to the storage andprocessing system 117 or theclient systems communication infrastructure 115. - The pluralities of
client systems post-processing systems 113. For example, some of the plurality ofclient systems 103 transmit geographic location (corresponding to either the location of the client system or any other selected location) to the storage andprocessing system 117, requesting related weather and speed information. In response to such request, the storage andprocessing system 117 uses the geographic location to access stored travel data to produce the related weather and speed information for delivery to the requesting client system. - The
communication infrastructure 115 may comprise a single communication network or a plurality of communication networks. Such networks may comprise wired and wireless portions. More specifically, collection of information and transmission of the collected information via thecommunication infrastructure 115 may be accomplished by using wireless transmission methods, such as General Packet Radio Service (GPRS) or Wideband Code Division Multiple Access (WCDMA). Collection and transmission on thecommunication infrastructure 115 may also be accomplished using radio, 802.11 network, ultrawideband communication, or any other means that allow sufficient freedom of movement. Delivery of information on thecommunication infrastructure 115 can be accomplished by using the same wireless transmission methods that are used for transmission of the collected information. In addition, delivery via thecommunication infrastructure 115 may be accomplished by using a cable infrastructure, a satellite network infrastructure, a digital subscriber line (DSL) infrastructure, an Internet infrastructure, an intranet infrastructure, a wired infrastructure, a closed communication infrastructure, and a local area network. Complimentary technology exists on the roadway traveldata exchange network 100, including the storage andprocessing system 117, and theclient systems - In an embodiment of the present invention, the roadway travel data exchange network may comprise a plurality of storage and processing systems. For example, in order to increase efficiency in the exchange of information, a storage and processing system may be placed near several major roads or intersections so that travel data may be reported to the storage and processing system which is closest to the reporting vehicle. The plurality of storage and processing systems may be connected together, or to a main storage and processing system, via the
communication infrastructure 115. The plurality of processing systems may each be deployed to provide different services or portions of an overall service offering. In such cases, the client systems may employ post-processing that correlates or otherwise combines the services or service information delivered by the plurality of processing systems. - In another embodiment of the present invention, a plurality of
client systems 103 may be utilized, as well as a plurality ofclient systems 119. Travel data that is collected by one or more of thecollection systems 111 on theclient systems 103 may be transmitted to, and processed by, a storage and processing system. Subsequent results may be utilized by thesame client systems 103 which collected the travel data, or byother client systems 103. The same results, however, may also be utilized by one or more of the retrieval/post-processing systems 113 on the plurality ofclient systems 119. -
FIG. 2 is a diagram illustrating a plurality of client systems on the roadway travel data exchange network ofFIG. 1 , for example, in accordance with various aspects of the present invention. The plurality ofclient systems 201 may comprise one or more of themultipurpose client systems 203 and/or one or more of thededicated client systems 205. More specifically, themultipurpose client system 203 may be, for example, one or more of a personal digital assistant (PDA) 207, acellular phone 209, alaptop computer 211, and a global positioning system (GPS)device 213. Themultipurpose client system 203 is enabled to collect, transmit, receive and deliver travel data. However, themultipurpose client system 203 may perform additional functions as well. For example, thePDA 207 may store and recall personal information. Thededicated client system 205 may only perform functions related to the travel data. Thededicated client system 205 may comprise aclient system 215 physically embedded (“hardwired”) in the vehicle. Adedicated client system 205 may also be designed as a portablededicated unit 217. -
FIG. 3 illustrates a more specific embodiment of one of theclient systems 201 in the roadway travel data exchange network ofFIG. 1 , for example, in accordance with various aspects of the present invention. In order to accomplish efficient exchange of travel data, theclient system 201 comprises auser interface 303, aprocessor 311 and acommunication interface 313. - The
client system 201 is adapted to collect, transmit, receive and deliver travel data. Where theclient system 201 is “dedicated” or embedded in a vehicle, avehicle interface 315 supports the collection of travel data related to the vehicle in which it is embedded. Such travel data may comprise, for example, information on the vehicle speed, tire pressure, airbag deployment, etc. - In the present embodiment, geographic location information of a vehicle is determined through location circuitry. If the location circuitry is present in the vehicle in which the client system is located, then the location circuitry will deliver the geographic location information to the
client system 201 via thevehicle interface 315. However, if the vehicle lacks location circuitry, theclient system 201 may comprise location circuitry within alocation interface 316. For example, in one embodiment, thelocation interface 316 comprises GPS (Global Positioning System) circuitry. In other embodiments, geographic location may be determined by any sufficiently reliable mechanisms for determining location, such as mechanisms employing triangulation techniques. The GPS circuitry may also assist in determining speed and direction of a vehicle if such travel data may not be collected directly via thevehicle interface 315. - The
user interface 303 comprises akeyboard 307, which may be used to enter travel data manually or otherwise interact with theclient system 201. For example, the keyboard might be used to request travel data from the storage andprocessing system 117. Of course, any other user input devices such as a touchscreen, mouse, buttons, dials or switches might also or alternatively be used. - Travel data which is delivered to the
client system 201 is displayed on adisplay 305. Theclient system 201 may also provide for audible notification of the received travel data viaspeakers 309. Information which is entered or received via theclient system 201 is processed by theprocessor 311. Acommunication interface 313 communicatively couples theclient system 201 with the communication infrastructure so as to provide access to the storage andprocessing system 117, for example. Through thecommunication interface 313, processed, post-processed and collected travel data is exchanged. For example, the storage andprocessing system 117 delivers processed travel data to theclient system 201 for display and audible output on thedisplay 305 andspeakers 309 respectively. -
FIG. 4 illustrates a diagram of an embodiment of a vehicle interface of the client system ofFIG. 2 , for example, in accordance with various aspects of the present invention. Thevehicle interface 315 provides functionality for collecting travel data that is related to the vehicle in which it is embedded. Travel data that may be collected by a client system may include, for example, a geographic location, a speed, a direction, an airbag status, an engine status, an outside temperature, a deployment status of vehicle brakes, a road precipitation status, a rollover status, a tire pressure status, a deployment status of an acceleration pedal, and a fuel level. -
FIG. 5 is a diagram illustrating an embodiment of post-processing information delivery systems on the roadway travel data exchange network ofFIG. 1 , for example, in accordance with various aspects of the present invention. Various post-processinginformation delivery systems 500 may be utilized in the retrieval/post-processing systems 113 ofFIG. 1 . Travel data communicated from the storage andprocessing system 117 may, for example, be delivered to atelephone 501, acomputer 503, atelevision 505, aradio 507, asatellite 509, or aroad sign display 511. - The
telephone 501 may, for example, be a dedicated telephone line. Users of the roadway travel data exchange network may dial this dedicated phone line and hear a recorded message with specific travel data. The contents of the recorded message may be periodically updated with new travel data. Several post-processing information delivery systems may be utilized at the same time. For example, information about an accident may be displayed on aroad sign display 511, while at the same time aradio 507 may broadcast information on alternate routes that may be utilized around the accident site. -
FIG. 6 is a diagram illustrating an embodiment of a storage and processing system on the roadway travel data exchange network ofFIG. 1 , for example, in accordance with various aspects of the present invention. The storage andprocessing system 117 comprises acommunication interface 605 for communicating with the roadway travel data exchange network via thecommunication infrastructure 115. Travel data received by the storage andprocessing system 117 via thecommunication interface 605 is processed by aprocessor 603, and is subsequently stored instorage 607. Thestorage 607 comprises several databases, which are associated with the type of travel data they contain. For example, thestorage 607 comprises atraffic database 609, aroadways database 611, and aweather database 613. Thetraffic database 609 stores all roadway travel data related to traffic. Theroadways database 611 stores information about the specific geographic location of a roadway network and specific roadway characteristics, such as type of road, length, maximum allowed speed, number of lanes, etc. The weather database stores the weather-related data that is received from an supportingcollection systems 105. The storage andprocessing system 117 may also comprise auser interface 601, which may allow an authorized user to directly input into the storage and processing system traffic-related, roadway-related, or weather-related information, or to edit existing information. -
